Selecting The Armstrong Air/Gas Vent
With the desired CFM capacity known, find the orifice size
required from the table on this page. Then find the vent or
vents with the correct orifice size on pages 457, 459, 461 or
469 that will operate at the required pressure with a liquid of
the specific gravity being handled.
Example—Find a model number that will vent 52 cfm of
air (including safety factor of 1.5 - 2.0) from a liquid with a
specific gravity of 0.93 at 250 psi. Using the table below,
follow the 250 psi line across to the number 60.9. Orifice
size is 5/32". Now go to pages 457, 459, 461 or 469
checking the 5/32" orifice lines to locate a vent for 250 psi or
higher with 0.90 gravity liquid.
NOTE: Since specific gravity falls between 0.95 and 0.90,
use 0.90 gravity data. The model 3-AV on page 456 is the
one to use.

For Venting During Filling Only
If a vent is required only for getting rid of air when a system
is started up, such as when starting up a deep well pump
or filling an empty pipe, tank or other vessel, ability of the
vent to open at operating pressure can be ignored. In these
cases, a model number with a large orifice for fast venting
may be selected, but the vent will not open after air is
expelled and the system reaches operating pressure.

1-AVC See-Thru Air Vent
For Pressures to 150 psig (7 bar) or Specific Gravity Down to 0.80
A See-Thru Body—So You’ll Know When It’s Working
Now, you can literally see what you’ve been missing—the
early warning signs of a system problem. Since you’ll know
the operating condition of the air vent, you won’t have
to waste time and money scheduling maintenance that
isn’t needed. In other words, you will be able to react to a
condition before it becomes a problem.
A simple ball float mechanism requiring no electricity to
operate, the new Armstrong 1-AVC discharges automatically
only when air/gas are present. That means no liquid loss as
with manual venting.
An Inside Look
See-thru body means you can observe changing conditions
as they occur. See a problem in the making—instead of
having to deal with it after the fact.
A
Efficient Operation
Simple ball float mechanism discharges only when air is
present so it doesn’t waste liquid.

Positive Seating
Free-floating valve mechanism assures positive seating so
it prevents liquid loss. There are no fixed pivots to wear or
create friction, and wear points are heavily reinforced for
long life.
Reduced Maintenance
Stainless steel internals mean corrosion resistance and
reduced maintenance.
Air Vents
Corrosion Resistance
Long-lasting polysulfone body and reinforced nylon cap
resist corrosion and provide long, trouble-free service life.

1-AVCW See-Thru Air Vent for Ozone Applications
For Pressures to 150 psig (10 bar) or Specific Gravity Down to 0.80
What Is Ozone?
Ozone is a gas that forms naturally during thunderstorms
when lightning converts normal oxygen molecules (O2) into
ozone (O3). The fresh, sweet smell in the air after a storm
is the smell of ozone. The unstable ozone molecule reacts
rapidly with most substances and is an extremely strong
natural oxidant.
A
How Is Commercial Ozone Produced?
Ozone can be formed by exposing air to ultraviolet light;
however, the most common method of generating ozone
is by passing air through an electrical discharge. Because
ozone has strong oxidizing properties, its production
requires corrosion-resistant equipment.
How Is Ozone Used in Water Filtration and Purification?
Because ozone is such an effective oxidant, it kills viruses,
bacteria, mold, mildew, fungus and germs. Passing ozone
through water achieves high purification rates without any
chemical residue. Oxygen is the only by-product.
Typical Customer Applications:
•Purifying standing ground water in Third World countries.
•Conditioning water for poultry and livestock.
•Purifying water in the bottled water industry.
•Filtering and purifying water for process applications.
A See-Thru Body Shows You It’s Working
Now, you can literally see what you’ve been missing. The
Armstrong 1-AVCW See-Thru Air Vent lets you easily check
its operating condition. You won’t have to waste time and
money scheduling maintenance that isn’t needed, and
you can quickly react to a condition before it becomes a
problem.
Positive Seating
Free-floating valve mechanism ensures positive seating and
prevents liquid loss. There are no fixed pivots to wear or
create friction. Wear points are heavily reinforced for long
life.
Corrosion Resistance
Long-lasting PBT (polybutylene terephthalate) cap provides
trouble-free operation. Stainless steel internal parts resist
corrosion and reduce maintenance.
Compare–and Save the Difference
Seeing really is believing–especially when you compare the
Armstrong 1-AVCW See-Thru Air Vent with manual venting.
Measure the time and money you can save with a more
efficient, easier-to-maintain system. For more information
or technical assistance, contact your local Armstrong
Representative.
NOTE: The Armstrong 1-AVCW should not be used in
an environment where there are high levels of ketones
or chlorinated or aromatic hydrocarbons.

Model 2-AV, 3-AV and 6-AV
Model 1-AV
Armstrong free floating lever Air/Gas Vents use the same
bodies, caps, lever mechanisms, valves and seats of
Armstrong inverted bucket steam traps that have been
proven in years of service.
1-AV—A cast iron air vent that uses a positive-closing
free floating lever to ensure leaktight closing under all
conditions. This vent is good for low capacity air/gas
venting up to 300 psi.
Elliptical floats and high leverage make it possible to open
large orifices to provide adequate capacity for vent size and
weight. The hemispherical valve, seat and leverage are
identical in design, materials and workmanship to those for
saturated steam service up to 1,000 psig, with the exception
of the addition of a guidepost to assure a positive, leaktight
valve closing under all conditions.
For a fully detailed certified drawing, refer to CD #1070.
2-AV, 3-AV and 6-AV—Cast iron vents using the same
proven free floating lever mechanisms used in Armstrong
steam traps. For applications where high air/gas venting
capacity is required up to 250 psi.
For a fully detailed certified drawing, refer to CD #1034.

Free Floating Lever Air/Gas Vents—Forged Steel
For Pressures to 1,000 psig (69 bar) or Specific Gravity Down to 0.40
High-Temperature Service
Maximum allowable working pressures of floats decrease at
temperatures above 100°F. Allow for approximately:
• 10% decrease at 200°F
• 15% decrease at 300°F
• 20% decrease at 400°F
The float is not always the limiting factor, however. Consult
with Armstrong Application Engineering if you have a
high-temperature application that also requires maximum
operating pressures.
Sour Gas Service
Forged steel and stainless steel traps can be modified to
resist hydrogen sulfide stress corrosion. These modifications
involve annealing the float, which will reduce the maximum
working pressure of the float to about half of its normal
value. Consult Armstrong Application Engineering for
allowable working pressures.

Free Floating Lever Air/Gas Vents—All Stainless Steel
For Pressures to 600 psig (41 bar) or Specific Gravity Down to 0.50
A
K
B
The Armstrong stainless steel free floating lever air vents
have been developed to provide positive venting of air/
gases under pressure.
Model 11-AV
A
The body and cap and all working parts of the No. 11-AV,
22-AV and 13-AV are made of high strength, corrosion
resistant stainless steel. Body and caps are welded together
to form a permanently sealed, tamperproof unit with no
gaskets. Elliptical floats and high leverage provide up to
115 SCFM capacity for these compact air/gas vents. Lever
action is guided to assure proper seating of the valve under
all operating conditions.
K
B
11-AV, 22-AV and 13-AV—All stainless steel construction
where exposure to either internal or external corrosion is a
problem. These air/gas vents have the same proven free
floating mechanisms used in other Armstrong steam traps.
Pressures to 600 psi @ 100°F (41 bar @ 38°C).

High Leverage Ball Float Type Air Relief Traps
For Low Flows at Pressures to 2,700 (186 bar) or Specific Gravity Down to 0.49
The Armstrong High Leverage Series of Air Relief traps
were developed especially for venting gases from low
specific gravity fluids at high pressures. They use standard
Armstrong forged steel bodies with very high leverage air
relief mechanisms. Available with screwed, socketweld or
flanged connections.

NOTE: Models 2313-HLAR, 2316-HLAR, 2413-HLAR and
2415-HLAR are also available with cast T-316 stainless
steel body and all-stainless steel internals. Consult factory.

Forged steel and stainless steel traps can be modified
to resist hydrogen sulfide stress corrosion. These
modifications involve annealing the float, which will reduce
the maximum working pressure of the float to about half its
normal value. Consult Armstrong Application Engineering
for allowable working pressures.

Armstrong offers Thermostatic Air Vents for positive venting
of air and other non-condensable gases from steam in
chamber type heat transfer equipment. Typical applications
include jacketed kettles, retorts, vulcanizers, jacketed
sterilizers or other contained equipment where air could
accumulate in remote areas of the steam chamber and
reduce heat transfer capacity. These vents are balanced
pressure air vents that respond to the pressure-temperature
curve of steam. Air is automatically vented at slightly below
steam temperature throughout the entire operating pressure
range.
Features
• Suitable for pressures from 0 - 300 psig
• All 304-L stainless steel bodies—sealed, tamper-proof
• Balanced pressure thermostatic element vents air
at slightly below steam temperature over the entire
pressure range—no adjustments required
• Dependable, proven phosphor-bronze bellows caged in
stainless steel with bronze valve and stainless steel seat
• Available in straight-thru or right-angle connections
Armstrong thermostatic air vents should be installed at the
highest point on a steam chamber, with the air vent located
above the chamber. This will minimize the possibility of
any liquid carryover, and air can be vented at atmosphere
without a drain line.
For a fully detailed certified drawing, refer to CD #1018.

TV-2 Thermostatic Air Vent
For Pressures to 125 psig (9 bar)…Capacities to 46 scfm
A
B
TV-2
Thermostatic Air Vent
Armstrong offers the Model TV-2 Balanced Pressure
Thermostatic Air Vent for positive venting of air from
chamber type heat transfer equipment with no loss of
steam. Typical applications include jacketed kettles,
retorts, vulcanizers, jacketed sterilizers or other contained
equipment where air could accumulate at the top of the
steam chamber and reduce heat transfer capacity.
The Model TV-2 is a balanced-pressure thermostatic air
vent that responds to the pressure-temperature curve of
steam at any pressure from light vacuum to maximum
operating pressure. Air is automatically vented at slightly
below steam temperature throughout the entire operating
pressure range.
The thermostatic element is a charged multi-convolution
phosphor bronze bellows caged in stainless steel. Valve and
seat are also stainless steel designed to meet the most rigid
cycling specifications known for this type of service.
Features
• Stainless steel hemispherical valve and seat
• Thermostatic element comprises a multi-convolution
phosphor bronze bellows caged in stainless steel
• Thermostatic element is charged with water to provide
positive opening of the valve at slightly below steam
temperature and positive closing in the presence of
steam throughout the operating pressure range
• ASTM B62 cast bronze body
Armstrong Model TV-2 Thermostatic Air Vents should be
installed at the highest points of steam chambers with inlet
connections to the vents higher than the highest points of
the chambers. Thus installed there is a minimum hazard of
any liquid carryover and air can be vented to atmosphere
with no drain line necessary.
For a fully detailed certified drawing, refer to CD #1032.

Bringing Energy Down to Earth
Say energy. Think environment. And vice versa.
Any company that is energy conscious is also
environmentally conscious. Less energy consumed means
less waste, fewer emissions and a healthier environment.
In short, bringing energy and environment together lowers
the cost industry must pay for both. By helping companies
manage energy, Armstrong products and services are also
helping to protect the environment.
Armstrong has been sharing know-how since we invented
the energy-efficient inverted bucket steam trap in 1911.
In the years since, customers’ savings have proven again
and again that knowledge not shared is energy wasted.
Armstrong’s developments and improvements in drain trap
design and function have led to countless savings in energy,
time and money. This section has grown out of our decades
of sharing and expanding what we’ve learned. It deals
with the operating principles of drain traps and outlines
their specific applications to a wide variety of products and
industries.
This section also includes Recommendation Charts that
summarize our findings on which type of drain trap will give
optimum performance in a given situation and why.
Terminology
Drain traps, as described in this section, have many
other names in industry. A drain trap is an automatic loss
prevention valve that opens to discharge liquids and closes
to prevent air or gas loss. In industry, drain traps are also
known as:
Liquid Drainers
n Compressed air drains
n Condensate drainers
n Air traps
n Water traps
476
LD-5
n Dump valves
n Float traps
n Liquid drainers
n Compressed air traps
This section should be utilized as a guide for the
installation and operation of drain trapping equipment
by experienced personnel. Selection or installation
should always be accompanied by competent technical
assistance or advice. We encourage you to contact
Armstrong or its local representative for complete details.

Instructions for Using the Recommendation Charts
Quick reference Recommendation Charts appear throughout
the “HOW TO DRAIN” pages of this section, pages LD-17 to
LD-28.
A feature code system (ranging from A to N) supplies you
with “at-a-glance” information.
The chart covers the type of drain traps and the major
advantages that Armstrong feels are superior for each
particular application.
For example, assume you are looking for information
concerning the proper trap to use on an aftercooler. You
would:
1.Turn to the “How to Drain Aftercoolers” section, pages
LD-21 and LD-22, and look in the lower left-hand corner
of page LD-21. (Each application has a Recommendation
Chart.) The Recommendation Chart LD-7 from page
LD-21 is reprinted below as Chart LD-1 for your
convenience.
2.Find “Aftercooler” in the first column under “Equipment
Being Drained” and read to the right for Armstrong’s
“1st Choice and Feature Code”. In this case, the first
choice is an IB and the feature code letters F, G, J, K, M
are listed.
3.Now refer to the chart below, titled “How Various Types
of Drain Traps Meet Specific Operating Requirements”
and read down the extreme left-hand column to each of
the letters F, G, J, K, M. The letter “F,” for example, refers
to the trap’s ability to handle oil/water mix.
4.Follow the line for “F” to the right until you reach the
column that corresponds to our first choice, in this case
the inverted bucket. Based on tests, actual operating
conditions, and the fact that the discharge is at the
top, the inverted bucket trap handles oil/water mixtures
extremely well. Follow this same procedure for the
remaining letters.

Compressed Air/Gases—Basic Concepts
Moisture is always present in compressed air, and oil can
be present at some points in a compressed air system. For
the efficient operation and long life of gaskets, hoses and
air tools, this excess moisture and the oil must be removed
from the system.
The removal of moisture and oil from a system involves
more than just traps. To maintain high efficiency and avoid
costly problems, a compressed air system also requires:
1. Aftercoolers to bring the compressed air down to
ambient or room temperature.
2. Separators to knock down suspended droplets of
water or fog. Separators are installed downstream from
aftercoolers or in air lines near point of use, or both.
3. Drain traps to discharge the liquid from the system with
a minimum loss of air.

Compressed Air/Gases—Basic Concepts
Water carried with air into tools or machines where air
is being used will wash away lubricating oil. This causes
excess wear to motors and bearings and results in high
maintenance expense. Without adequate lubrication, the
tools and machines run sluggishly and their efficiency is
lowered. This effect is particularly pronounced in the case of
pneumatic hammers, drills, hoists and sand rammers, where
the wearing surfaces are limited in size and the excessive
wear creates air leakage.
Where air is used for paint spraying, enameling, food
agitation and similar processes, the presence of water and/or
oil cannot be tolerated, nor can particles of grit or scale.
Air’s Capacity to Hold Moisture
At atmospheric pressure (14.7 psia), 8 cu ft of air with an
RH of 50% and a temperature of 70°F will contain 32 grains
of moisture vapor.
In instrument air systems, water will tend to cling to small
orifices and collect dirt, causing erratic operation or failure of
sensitive devices.
Pipeline Troubles
When water accumulates at low points in the pipeline, the
air-carrying capacity of the line is reduced. Eventually,
airflow over the pool of water will begin to carry the water
along at high velocity. This produces “water hammer” along
the line, and may even carry over a slug of water into a tool.
In cold weather, accumulations of water may freeze and
burst pipelines.
Increasing the pressure to 100 psig (114.7 psia), the volume
of air is further reduced to approximately 1 cu ft. This 1 cu
ft of compressed air still at 70°F can hold a maximum eight
grains of moisture.
When the pressure is doubled (without increasing the
temperature) the volume is cut in half (4 cu ft), but there are
still 32 grains of moisture. This means the relative humidity
is now 100%—all the moisture in vapor form that it can
handle.

Compressed Air/Gases—Basic Concepts
Drainage Problems and How to Avoid Them
Oil. A critical drainage problem exists at points where
oil may be present in the compressed air (principally at
intercoolers, aftercoolers and receivers).
Two facts create this problem:
1. Oil is lighter than water and will float on top of water.
2. Compressor oil when cooled tends to become thick and
viscous.
The beaker simulates any drain trap that has its discharge
valve at the bottom, Fig. LD-4. Like the beaker, the trap will
fill with heavy oil that may be thick and viscous.
Compare with Fig. LD-5, which shows an identical beaker
except that the discharge valve is at the same level as the
oil. Oil will escape until the oil level is so thin that for every
19 drops of water and one of oil that enter the beaker,
exactly 19 drops of water and one drop of oil will leave. The
beaker always will be filled with water.
The conclusion is obvious. When there is an oil-water mixture
to be drained from an air separator or receiver, use a trap
with the discharge valve at the top.
Air Loss. Often in compressed air systems, the solution
to one problem may also cause another problem. For
example, a common method of draining unwanted moisture
is to crack open a valve; however, this also creates a leak.
The immediate problem is solved, but the “solution” has an
obvious, and usually underestimated, cost of continual air
loss.
How much air is lost depends on orifice size and line pressure
(see Table LD-2). The overall result is a decrease in line
pressure, the loss of up to a third of the system’s compressed
air, and the cost of compressing it.
Leak control involves:
n Looking for leaks during shut-down with an ultrasonic
leak detector
n Determining total leakage by observing how fast
pressure drops with the compressor off, both before and
after a leak survey
n Fixing leaks at joints, valves and similar points
n Replacing cracked-open valves with drain traps
n Checking the system regularly
Dirt and Grit. While scale and sediment is seldom a problem
between the compressor and receiver, it is encountered
in the air distribution system, particularly when the piping
is old. In this situation, scale will be carried to a drain trap
along with the water. If the drain trap is not designed to
handle dirt and grit, the trap may fail to drain water and oil,
or the trap valve may not close.
Figure LD-6. Drain Trap Locations in a Compressed Air System
The use of drain traps is an effective way to remove water
that collects in many places in a compressed air system.
Each trap location must be considered individually.

Compressed Air/Gases—Basic Concepts
Drainage Methods
Manual. Liquid may be discharged continuously through
cracked-open valves, or periodically by opening manually
operated drain valves.
Open drains are a continuous waste of air or gas—and
the energy to produce it. A valve manually opened will be
left open until air blows freely. Frequently, however, the
operator will delay or forget to close the valve, and precious
air or gas is lost.
Automatic. Automatic drainage equipment that is adequate
for the system is seldom included in the original system.
However, subsequent installation of automatic drain traps
will significantly reduce energy and maintenance costs.
The job of the drain trap is to get liquid and oil out of the
compressed air/gas system. In addition, for overall efficiency
and economy, the trap must provide:
n Operation that is relatively trouble-free with minimal need
for adjustment or maintenance
n Reliable operation even though dirt, grit and oil are present
in the line
n Long operating life
n Minimal air loss
n Ease of repair

Drain Traps. Water collected in separators and drip legs
must be removed continuously without wasting costly air or
gas. In instances where drain traps are not part of the system
design, manual drain valves are usually opened periodically
or left cracked open to drain constantly. In either case, the
valves are opened far enough that some air and gas are lost
along with the liquid. To eliminate this problem, a drain trap
should be installed at appropriate points to remove liquid
continuously and automatically without wasting air or gas.

Inverted Bucket Drain Traps
For Heavy Oil/Water Service
BVSW inverted bucket drain traps are designed for systems
with heavy oil or water services.
An inverted bucket is used because the discharge valve
is at the top, so oil is discharged first and the trap body is
almost completely filled with water at all times.
BVSW stands for Bucket Vent Scrubbing Wire. This 1/16'' dia.
wire swings freely from the trap cap and extends through
the bucket vent. Its function is to prevent reduction of vent
size by buildup of solids or heavy oil in the vent itself. The
up-and-down motion of the bucket relative to the vent scrubbing
wire keeps the vent clean and full size.
Operation of Inverted Bucket Drain Traps
1. Since there is seldom sufficient accumulation of water
to float the bucket and close the valve, the trap must be
primed on initial start-up or after draining for cleaning.
Step 1 shows “after operating” primed condition with oil
in the top of bucket and a very thin layer of oil on top of
water in the trap body.
2. When valve in line to trap is opened, air enters bucket,
displacing liquid. When bucket is two-thirds full of air, it
becomes buoyant and floats. This closes the discharge
valve. As bucket rises, the vent scrubbing wire removes
oil and any dirt from bucket vent.
Both liquid and air in trap are at full line pressure, so no
more liquid or air can enter trap until some liquid or air
escapes through the discharge valve. Static head forces
air through bucket vent. The air rises to top of trap and
displaces water that enters bucket at bottom to replace
air that passes through vent. Just as soon as bucket
is less than two-thirds full of air, it loses buoyancy and
starts to pull on valve lever as shown in Step 3.

Inverted Bucket Drain Traps
3. Note that liquid level at top of trap has dropped and the
liquid level in the bucket has risen. The volume of water
displaced by air exactly equals the volume of water
that entered the bucket. During this valve-closed part of
the operating cycle—Steps 2 and 3—water and oil are
collecting in the horizontal line ahead of the trap. When
the bucket is about two-thirds full of liquid, it exerts
enough pull on lever to crack open the discharge valve.
4. Two things happen simultaneously. a) The accumulated
air at top of trap is discharged immediately, followed by
oil and any water that enters the trap while the valve
is cracked. b) Pressure in trap body is lowered slightly,
allowing accumulated liquid in horizontal line to enter
the trap. Air displaces liquid from the bucket until it floats
and closes the discharge valve, restoring the condition
shown in Step 2.
5. When full buoyancy is restored, the trap bucket is twothirds full of air. Oil that has entered while trap was open
flows under bottom of bucket and rises to top of water in
trap body. The trap normally discharges small quantities
of air several times per minute.

Float Type Drain Traps
Closed Float
Hollow, thin-wall metal floats are attached through linkages
to valves at the trap bottom, and a seat with an appropriately
sized orifice is inserted at the trap outlet. Floats are selected
to provide adequate buoyancy to open the valve against the
pressure difference. Discharge usually is to atmosphere, so
the pressure drop is equal to the system air pressure. The
float and linkage are made of stainless steel, and the valve
and seat are hardened stainless steel for wear resistance
and long life. The body is cast iron, stainless steel, or cast
or forged steel depending on gas pressure. Bodies may be
made of stainless steel to resist corrosive gas mixtures.
lowers water level further opening or throttling the valve.
Thus discharge is proportionally modulated to drain liquid
completely and continuously. However, gas flow may be
constant or it may abruptly change depending on system
demand characteristics. Liquid formation may be sporadic, or
the nature of flow generation may cause surges. At times,
flow will be very low, requiring operation to throttle the flow
or even tight shut-off. Tightness of closure, gas leakage and
trap cost will depend on the design of linkage and valve.
Entering liquid drops to the bottom of the body. As liquid
level rises, the ball is floated upward, thereby causing
the valve to open sufficiently that outlet flow balances
inlet flow. Subsequent change of incoming flow raises or
The discharge from the No. 1-LD is continuous. The
opening of the valve is just wide enough to remove the
liquid as fast as it comes to the trap. Thus, at times, the
valve is barely cracked from its seat.

Free Floating Linkage Valve
A hemispherical ball-shaped valve is attached to linkage
which is suspended freely on two guide pins. There is no
fixed pivot or rigid guides; therefore, the attachment is loose.
There are no critical alignments, and the lever and valve
may move in all directions. Consequently, the lever may
move the valve to the seat in any alignment. As the valve
approaches the seat, the pressure pushes the round valve
into the square edge orifice of the seat, effecting a line seal
to attain bubble-tight closure.

Figure LD-10. Operation of No. 21 Fixed Pivot Drain Trap
As the water level rises, the ball float cracks the valve to drain liquid at
the same rate that it reaches the trap. Changes in the rate of flow to
the trap adjust the float level and the degree of opening of the valve.
Snap Action Valve
Because of the sporadic liquid flow, much of the time
the valve in a standard float-type drainer is only slightly
opened. If there is fine dirt or grit in the liquid, particles may
accumulate and clog the partially open valve, or they may
lodge between the valve and seat, preventing closure. To
overcome this, a special toggle-spring operated valve is
used.
A flat spring attached to the leverage system holds the valve
closed until liquid level is high enough for the buoyancy to
exceed the spring force. Then the valve is snapped open,
and the accumulated dirt and grit can be flushed through the
wide open valve. When the body is nearly empty, buoyancy
is reduced enough to permit the spring to snap the valve
closed.

Drain Trap Selection
To obtain the full benefits from the traps described in the
preceding section, it is necessary that the correct size and
pressure of drain trap be selected for each job, and that it
be properly installed and maintained.
Rely on Experience. Most drain traps are selected on the
basis of experience. This may be:
n Your personal experience
n The experience of your Armstrong Representative or
distributor
2. Pressure Differential. Maximum differential is the
difference between main pressure, or the downstream
pressure of a PRV, and return line pressure. See Fig.
LD-12. The drain trap must be able to open against this
pressure differential.
Operating differential. When the plant is operating at
capacity, the pressure at the trap inlet may be lower than
main pressure. And the pressure in the return header may
go above atmospheric.
n The experience of thousands of others in draining
If the operating differential is at least 80% of the maximum
differential, it is safe to use maximum differential in selecting
traps.
Do-It-Yourself Sizing is required at times. Fortunately,
drain trap sizing is simple when you know or can figure:
1. Liquid loads in lbs/hr.
2. Pressure differential.
3. Maximum allowable pressure.
IMPORTANT: Be sure to read the discussion on page LD-16,
which deals with less common, but important, reductions in
pressure differential.
identical equipment
1. Liquid Load. Each “How To” section of this handbook
contains formulas and useful information on proper sizing
procedures and safety factors.
3. Maximum Allowable Pressure. The trap must be
able to withstand the maximum allowable pressure of the
system, or design pressure. It may not have to operate at this
pressure, but it must be able to contain it. As an example,
the maximum inlet pressure is 150 psig and the return line
pressure is 15 psig. This results in a differential pressure of
135 psi; however, the trap must be able to withstand 150 psig
maximum allowable pressure. See Fig. LD-12.

Drain Trap Selection
Factors Affecting Pressure Differential
Pressure Differential in Detail
Inlet pressure can be:
1. Air main pressure.
2. Reduced pressure controlled by a pressure reducing
valve station.
Discharge can be:
1.Atmospheric.
2. Below atmospheric—under vacuum. Add vacuum
to inlet pressure to get pressure differential.
2" Hg vacuum = approximately 1 psi of pressure
below atmospheric.
3. Above atmospheric due to:
a.Pipe friction
b.Elevating liquid
Every 2' lift reduces pressure differential by approximately
1 psi, when the discharge is only liquid.
Special Considerations
Drain traps are available for services other than those found
on standard compressed air systems.
High Pressure
Spring-loaded mechanisms allow float type drain traps to
operate on pressures above 3,000 psi.
Fluids Other Than Water
Different fluids, such as oils and liquid, can be compensated
for with specially weighted floats or lower operating pressure
ratings. Fluids with specific gravities down to 0.4 will work
with float type drain traps.
Materials of Construction
Service requirements for stainless steel or other corrosionresistant materials can be met by float and inverted bucket
type drain traps.
NACE Sour Gas Service
Special materials and construction are required for hydrogen
sulfide service.
High Capacity for Large Flow Rates
Ultra-capacity type drain traps allow float type drain traps to
be used on service requiring capacities up to 700,000 lbs/hr.
Dual Gravity
Float type drain traps can be modified to drain a heavier
fluid from a lighter fluid.

How to Drain Air Distribution Systems
Air distribution systems make up the vital link between
compressors and the vast amount of air-utilizing equipment.
They represent the method by which air is actually
transported to all parts of the plant to perform specific
functions.
The three primary components of air distribution systems
are air mains, air branch lines, and air distribution manifolds.
They each fill certain requirements of the system, and together
with separators and traps, contribute to efficient air utilization.
Common to all air distribution systems is the need for drip
legs at various intervals. These drip legs are provided to:
Air mains are one of the most common applications for
drain traps. These lines need to be kept free of liquid to
keep the supplied equipment operating properly. Inadequately
trapped air mains often result in water hammer and slugs of
liquid, which can damage control valves and other equipment.
There is also a freeze potential wherever water is allowed
to accumulate. In areas where air is moving slowly, the
accumulation of water can effectively reduce the pipe size,
thereby increasing the pressure drop and wasting energy.
1. Let liquid escape by gravity from the fast-moving air.
2. Store the liquid until the pressure differential can
discharge it through the drain trap.
3. Serve as dirt pockets for the inevitable dirt and grit that
will accumulate in the distribution system.

How to Drain Air Distribution Systems
Selection of Drain Traps and
Safety Factor for Air Mains
Traps should be selected to discharge a volume of liquid
normally produced when the system is up and running.
Liquid loads can be estimated if actual CFM or air volume
flow is not known. If cold temperatures are possible, the
dew point at supply pressure must be known. Once this
maximum is determined, the safety factor used to size the
trap will be only 10% of the total potential liquid load. Ten
percent of the total is used because most of the liquid has
been removed in the aftercooler and receiver. The drain trap
must handle only the small remaining amount of 10% of the
total possible load.
Rule of Thumb for Calculating
Compressor Liquid Loads
CFM x 20 gr/cu ft x 60 min/hr
= #/hr
7,000 gr/#
1. Assuming worst condition:
100°F @ 100% RH
For other conditions, see page LD-7
2. Using air main safety factor of: Load x 10%
If actual airflow rate is not known, it can be estimated using
Chart LD-4, titled “Pressure Drop in Compressed Air Pipe.”
Using an assumed pressure drop of 1/4 (.25) psi per 100 ft,
and 100 psi gauge pressure of air through a 4" line, it can
be seen that approximately 1,000 cu ft of free air per minute
are flowing through the line. Taking this figure to the chart
titled “Water Condensed From Compressed Air,” Chart LD-6
on page LD-20, it can be seen that if 80°F, 90% RH air is
delivered at 100 psi, then 1.2 lbs of water will be condensed
per minute at 1,000 CFM. This number will be multiplied by
60 to convert from minutes to hours, which equals 72 lbs/hr.
For this air main then, take 10% of this figure, or 7.2 lbs/hr,
to be the flow rate to the drainer.
Installation of Drain Traps on Air Mains
Drip Legs. All air mains should utilize drip legs and traps
at all low spots or natural drainage points, such as ahead
of risers, end of mains, ahead of expansion joints or bends,
and ahead of valves and regulators (see installation Fig.
LD-17).
Where there are no natural drainage points, drip legs and
drain traps should still be provided. These should normally
be installed at intervals of about 500 ft.

How to Drain Air Distribution Systems
Branch Lines
Branch lines are takeoffs of the air main supplying specific
areas of air-utilizing equipment. Branch lines must always
be taken from the top of the air main. The entire system
must be designed and hooked up to prevent accumulation
of liquid at any point. If a specific process area requires it,
an air dryer will be installed on the branch line.
Trap Selection and Safety Factor for Branches
The formula for computing liquid load in branch lines is the
same as that used for air mains. Branch lines also have a
recommended safety factor of 10% of total air load. Drip legs
must be installed ahead of risers and at the end of branch
lines, especially when branch line runouts exceed 50 ft.
There are usually several branches off the air main, and in
many cases they experience a high liquid load when they
run against cold outside walls. This cooling causes more
moisture to condense in the branch line than would be seen
in the air main.
Distribution Manifolds
A distribution manifold is a terminal for a branch line from
which several air users are taken off. They are particularly
common in manufacturing facilities for pneumatic tool
hookups or takeoffs to cylinder actuators. Like branch lines,
it is common for distribution manifolds to be installed against
cool walls where low temperatures cause condensation and
the accumulation of liquid.
Since the air distribution manifold is usually one pipe size
larger than the branch line, it is common for air velocity to
drop when coming from the branch line. With this decrease in
velocity, often combined with lower ambient temperatures,
it is common for a liquid to accumulate in the distribution
manifold. For this reason, the use of filter-drainer combinations
or separate drain traps is recommended. Trapping the liquid
in the distribution manifold is important to protect the regulators
on air-using equipment and orifices in air-using instruments.
This is a location where manual valves are commonly
misused due to their accessibility. To drain the liquid and
keep it from fouling an instrument or pneumatic tool, manual
valves will often be cracked to atmosphere. When they
are left this way, the result is a large air loss due to the
unrestricted free blow of air to atmosphere.
Trap Selection and Safety Factor for Distribution Manifolds
Normally the smallest drain trap is practical for distribution
manifolds up to manifold diameters of 2''. Above 2'', the
distribution manifold should be considered a branch, and
then the sizing procedure from the Air Main section would
apply.
Liquid Drainers
Distribution manifolds are often equipped with filters and
regulators. Regulators may also be found at the termination
before the air-using device.

Installation
The ABCs of trap installation must be followed: “A” for
accessible, “B” for below the point being drained, and “C”
for close to the point being drained. If the discharge point for
this drain trap is some distance away from the drain point,
the discharge line from the trap should be run out—not the
inlet to the trap.
When installing traps on the drain connection of filters,
particular care should be taken to the connection size.
Normally outlet connections on filters are 1/4'' in size or less.
This connection size is normally not large enough to allow
anything but slugs of liquid to flow into the trap housing. If
a float trap is utilized, it should be either back vented or the
connection size must be increased to 3/4'' minimum. For
additional installation recommendations, see pages LD-51
and LD-52.

removal on industrial air systems. It increases the efficiency
of air distribution by reducing pressure drop created when
air flows through the system. It does this by using cooling
water to reduce the specific volume of the air which, in turn,
allows the air to flow through the system with less pressure
drop. Aftercoolers are found on most industrial compressors
over 10 hp in size. In addition to removing the heat of
compression, aftercoolers also remove approximately twothirds of the liquid found in the air, and help in the removal
and knock-down of oil carryover from the compressor.
Intercooler
Compressor intercoolers are designed to increase the
efficiency of compression by reducing the temperature
and specific volume of air between stages of compression.
This allows the compressor to do more work at a lower
temperature than would normally occur. Because some
condensing will occur in the intercooler, a drain trap is
required to protect compressor parts.
If liquid were to carry over from the intercooler, it could
also carry dirt or scale into the compressor and/or also
cause corrosion within the compressor, both of which are
undesirable for efficient compressor operation. If slugs of
liquid were to pass from the intercooler into the compressor,
it would make the compressor operation erratic. Efficient
trapping is required at this point to deliver dry air to the next
stage of the compressor.
Liquid Drainers
An intercooler is typically a shell and tube heat exchanger.
Liquid condensate flow out of the heat exchanger is usually
irregular, causing slugs to accumulate and pass into the
drain trap. Because of this, a drip leg is required on the
intercooler, and full size outlet piping from the intercooler
must be used into a dirt pocket. The drip leg allows the slug
of condensate to be handled by the drain trap and handles
some small backup while the drain trap is discharging the
liquid.
The intercooler may also experience oil carryover if the
compressor is not of the oil-less or sealed type. As air enters
the intercooler, it carries a mist or tiny droplets of oil along
with it. Because the air is at a relatively high temperature,
this oil is fairly thin. Then, as the intercooler cools the air
and oil, the oil may thicken. The drain trap must be able to
discharge this oil before it thickens and negatively affects
the drain trap and intercooler operation. Trap selection is
very important in this type of application where a water and
oil mix must be handled by the trap and the oil must be
discharged first.
Since the aftercooler removes approximately two-thirds of
the total moisture load, traps here will normally be much
larger than those found on the rest of the system.
Trap Selection and Safety Factor
Intercooler
Select the proper trap for:
1. Entering water temperature into the intercooler.
2. Airflow rate through the intercooler.
3. Intermediate pressure at which the intercooler
is operated.
Use Chart LD-6 on page LD-20, “Water Condensed
From Compressed Air,” to determine the pounds of water
condensed per minute in 1,000 CFM. Then multiply by 60
to convert minutes to hours and use a safety factor of 2:1.

How to Drain Intercoolers, Aftercoolers,
and Aftercooler Separator Combinations
When selecting the type of trap, consider the failure mode
and the ability of the trap to respond to slugs of liquid. In
most cases, an “open” failure mode will be desirable as it is
vital to protect the compressor from slugs of liquid. A quick
response to slugs is important so there is no delay between
the time the liquid accumulates and the trap discharges the
liquid.
Aftercooler
When the aftercooler condensing rate is not known, there
are two typical methods for calculating condensate load.
The first method is to calculate total airflow through the
system. Then using Chart LD-6 on page LD-20, titled “Water
Condensed From Compressed Air,” determine pounds of
water condensed per minute in 1,000 CFM. Multiply this by
60 to convert minutes to hours for required trap capacity
in pounds per hour (the entering maximum incoming
summertime temperature and relative humidity must be
known to use this chart). This load is then multiplied by 2 to
determine required trap capacity.
The second method of calculating trap capacity is to look
at maximum allowable flow rate through the aftercooler.
Use the “Water Condensed From Compressed Air” chart on
page LD-20 in the same manner as described in Method 1.
Although this method will normally yield a larger trap size,
it allows for the addition of another compressor or the
interconnection of several compressors to the system in the
event of unplanned by-passes.
In the second method, it’s important to estimate the average
water temperature within the aftercooler as closely as
possible. Not all air actually comes in contact with the water
tubes; therefore, the air is not uniformly cooled to the water
temperature. If actual leaving air temperature is known, this
is by far the most accurate figure to use. A properly sized
aftercooler will normally cool compressed air down to within
15°F of entering air temperature.
Installation
When installing drain traps on aftercoolers or aftercooler
separator combinations, the “ABCs” of trap installation
should be followed:
Accessible for maintenance and repair.
Below the point being drained.
Close to the drip point as possible.
Be sure to follow manufacturer’s instructions on trap
installation. Most aftercoolers are equipped with a separate
separator. However, if a separator is not furnished, the
aftercooler must be trapped individually. In the case of
the aftercooler/separator combination, only the separator
normally requires a trap. See Fig. LD-18 or LD-19. But
again, it is important to follow manufacturer’s instructions.
For additional installation recommendations, see pages
LD-51 and LD-52.

How to Drain Separators, Separator Filter Combinations
Separators serve an important function within the compressed
air system. Separators may also be known as knockout
pots, knockout drums or demisters. Their function is to
remove liquid that may be moving at a high speed from the
flowing air, and they normally perform this function in a twostep process.
1. Separators increase the flow area and volume of the
gas, thereby reducing its velocity. Air within the system
may flow at velocities exceeding 100 mph. At this
velocity any liquid will be entrained as droplets and will
not be flowing along the bottom of the pipe. To remove
these liquid droplets, it is necessary to reduce the
velocity of the gas; otherwise, the droplets accumulate
and again become entrained with the flowing gas.
2. The second step is to change direction and impinge the
liquid. As the velocity of the gas is reduced, the velocity
of the fast-moving droplets can be reduced even further
by causing the air to take either 90-degree turns or to
centrifugally flow within a chamber. Both of these methods
serve to “sling” the droplets up against baffles, plates or
the wall of the separator.
Locations
Separators are normally located on the leaving side of
aftercoolers and before the compressed air receiver. They
are often integral with filters located before sensitive airusing equipment or as part of the filter on a distribution
manifold. In this case there may be a combination filter,
oiler, regulator and separator drainage point for liquids to
accumulate.
Trap Selection and Safety Factor
If the separator is part of an aftercooler combination
installed between the compressor and the receiver, you
should refer to the section on Aftercoolers and Aftercooler
Separators for trap selection.
Trap selection is fairly critical, especially on equipment
with larger than 1" air lines feeding it, since slug formation
can wash scale into the air-using equipment and become
a serious dirt problem. Therefore, on larger than 1"
separators, the flow should be calculated by totaling the air
consumption of the devices downstream and using Chart
LD-6, “Water Condensed From Compressed Air,” on page
LD-20. Use the full water load expected and the safety
factor of 3:1 to figure trap capacity.
Liquid Drainers
Because the droplets have a relatively high mass and are
incompressible, their velocity will drop dramatically. At this
point, gravity will take over, causing the drops to accumulate
and flow into the bottom of the separator. Liquid will often
fall in sheets down the wall of the separator and collect at
the outlet piping in slugs. The immediate drainage of the
slugs is important since the separator is normally a final
opportunity to protect an air-using device downstream.
If liquid is allowed to accumulate for any amount of time,
it may undermine the entire purpose and function of the
separator. Therefore, if the separator does not do its job
efficiently, it can actually become a reservoir that accumulates
condensate and forms slugs to be transmitted down the air
line and into the device being protected. In this case, the
use of a separator may be worse than no protection at all.

How to Drain Separators, Separator Filter Combinations
To determine proper trap capacity for separators with a pipe
size of less than 1", the flow can be estimated by using
Chart LD-6, “Water Condensed From Compressed Air,” on
page LD-20, and then calculating 20% of full load.
The safety factor for both selection procedures is 3:1 since
separators must respond to surges of liquid from the inlet.
In this case, the trap must handle far more liquid than would
be experienced under normal operation.
Installation
When installing ball float type traps on separators 1" and
above, it’s important to back vent the trap (refer to the section
on how to hook up ball floats for the purpose and function
of back vent lines, page LD-51). All other types of drainers
should be coupled as closely as possible to the drain leg.
The drain leg should be the same size as the drain connection
on the separator and extend 6" below the separator with
another 6" allowed for a dirt pocket. The trap is then tee’d
off this line (see Figs. LD-20 and LD-21). This piping is
crucial because, as noted above, if the separator does not
receive full drainage, it can be worse than no separator at
all. For this reason, the “ABCs” are critical:
Accessible for inspection and maintenance.
Below the equipment being drained.
Close to the drain point.
The line size leading from the drip leg to the inlet of the
unit should be kept the same size as the trap inlet for good
drainage into the trap. Again, when slugs are being handled
it’s important that the trap begin draining immediately. Back
vents on float type traps should be a minimum of 1/2" in pipe
size with 3/4" preferred. Any valves used in this back-vent
piping should be full ported to allow free gas flow out of
and liquid flow into the drain trap. For additional installation
recommendations, see pages LD-50 to LD-52.

How to Drain Receivers
Receivers perform the vital function of storing air for the
system. The receiver dampens pressure fluctuations in the
system and provides a very short storage time in the event
of compressor failure. It also functions as a liquid knockout
drum to prevent entrained liquid (which may carry over)
from entering the compressed air dryer or the air mains.
The receiver should be sized to provide enough storage
time for an orderly shutdown, particularly in the case of
instrumentation air systems. Receiver volume is what
provides the amount of air required for storage periods.
The receiver should be located close to the compressor.
Fallout of liquid is normal due to low velocity within the
receiver. Velocity is at the lowest point it will reach in any
other part of the operating system. The air has a high dwell
time within the receiver and is more likely to cool to ambient.
This cooling of the air is what causes moisture to condense.
The receiver is equipped with a drain port at the bottom to
allow liquids to flow to drain traps. In many cases, because
receivers are so large and located adjacent to the compressor,
they are installed close to the floor. When this happens, the
drain point is relatively inaccessible, making trap piping difficult
and gravity flow into the trap often impossible. To avoid this,
the receiver should be located on a small concrete pad, which
will facilitate efficient drain trap installation and operation.
Trap Selection and Safety Factor
To select the proper trap for the receiver, it is necessary
to calculate total system load using Chart LD-6, “Water
Condensed From Compressed Air,” on page LD-20. Once
this total potential load is known, it will be multiplied by the
following factors: With an aftercooler, multiply the load by
50%, with an aftercooler separator combination, multiply the
total load by 40%, and if no aftercooler is present, multiply
the total load by 70%. Once this load is known, a safety
factor of 2:1 is applied.

System Load with
Aftercooler

Liquid Drainers
For several reasons, it’s good to keep the receiver drained.
When receiver volume is lost, the dampening of the
compressed air pressure is reduced and the storage time
between compressor failure and system shutdown is greatly
reduced. Corrosion within the receiver can also take place
when liquid is allowed to accumulate.
Manual valves are commonly used to drain receivers since
they are typically installed close to the floor. The resulting
loss of receiver volume is seldom noticed in the day-to-day
operation of the system. However, with any manual system,
the valve can be forgotten and not opened. Then, when
the weather changes from a relatively dry, low moisture
load to a warm, high moisture load, the receiver will lose
volume and the dampening effect and accumulator effect
are decreased. The compressor can short cycle under these
conditions, increasing the wear and tear on the compressor.
In addition, the only reminder to open the manual valve is
when carryover occurs. In this case, an air dryer can be
damaged, liquid can be introduced into the air mains and
surge through the system, causing scale to be washed into
the system, water hammer and/or freeze damage.

How to Drain Receivers
Installation
When a float type drain trap is used with a receiver, the
level will run at about the inlet connection on the trap.
Therefore, it is important to locate the trap as close to the
floor as feasible and with no dips in the piping. See Figs.
LD-22 thru LD-25. If there is a piping dip with a float type
unit and the vent connection is not back vented, the unit will
fail to operate. In the case of a back-vented unit, the dip in
the piping will be flooded at all times. An inverted bucket
trap can be installed above floor level since it will operate
above the drain point. An internal check valve, tube and coupling should be installed to prevent the liquid seal from flowing backward on system shutdown. A snap action type float
unit should be used when any amount of grit is expected
in the system. In this case, the spring life can be extended
by moving the drain trap slightly upward to allow liquid to
accumulate both within the receiver and within the trap body
between trap cycles. For additional installation recommendations, see pages LD-50 to LD-52.

How to Drain Dryers
The function of dryers is to eliminate liquid in applications
where freezing or any moisture accumulation can cause
serious problems with the air-consuming equipment. Dryers
should always be installed on instrument quality air systems.
Two basic dryer types are dessicant and refrigerated. In the
dessicant type, the dessicant chemical absorbs the liquid
by chemically bonding with the water molecules. Dessicant
dryers can achieve very low dew points and are often
installed with a pre-dryer of the refrigerant type. Refrigerant
dryers work the same as aftercoolers by circulating cold fluid,
causing the moisture to condense. However, their ability to
reach low dew points is limited by the temperature at which
frost will form on the heat exchanger tubing (greatly reducing
heat transfer).
This leads to a discussion of air dew point. Dew point is the
temperature at which moisture will condense out from the
air due to its relative humidity increasing above 100%; see
Chart LD-11. When this happens, the moisture condenses
out and can be drained to a drain trap. Dew point is also
important when considering air that has left the dryer, because
if the air is ever exposed to temperatures below its dew
point, moisture will form. Therefore, when applying air dryers,
it is important to consider two features of compressed air
usage that will impact dryer selection.
1. When air is compressed, the dew point is increased.
Also, the dew point under pressurized conditions must
be known. For example, even though a -40°F dew point
is achieved at atmospheric conditions, this becomes
a dew point of about 10°F once the air has been
compressed to 100 psi. In outdoor systems, when the
temperature drops below 10°F, condensing and freezing
of that moisture will result.
2. When compressed air is expanded through instruments
or air tools, its volume increases, pressure decreases
and a temperature drop is usually experienced. If the
temperature drops below the dew point of the air,
undesirable moisture forms in the equipment. The air
would never be subjected to that temperature under any
conditions other than when expanding.

How to Drain Dryers
Drain traps are usually required on refrigerated type dryers
only. Here the refrigerant chills air and creates moisture that
the drain trap can discharge. In the case of the dessicant
type air dryer, the chemical grabs the moisture and
bonds chemically with the water molecules, and no liquid
accumulates. These bonded water molecules are then
usually driven off in a regeneration cycle the dryer must
periodically undergo.
Trap Selection and Safety Factor
In most cases, the dryer manufacturer will rate the dryer
for a given moisture removal rate. The safety factor should
still be applied to this load, however. If the manufacturer’s
ratings are not known, then it’s necessary to calculate the
moisture content of the air at aftercooler conditions and the
moisture content at ambient conditions. Using the lower
moisture content between these two, compare that figure
to the moisture content at the dew point of the air leaving
the dryer. The difference in these moisture contents is then
multiplied by the airflow through the dryer to determine the
moisture load. The safety factor applied to the load is 2:1
since liquid should be drained immediately from the dryer
and the liquid tends to flow into the drain trap in slugs.
Installation
The dryer should come with a drain port of a given pipe size
sufficient to handle the liquid coming out of the dryer. In this
pipe size, a drain leg should be piped up 6" below the dryer
with another 6" below that as a dirt pocket. Teeing off this
line and into the trap with the same inlet size as the trap will
allow for gravity drainage into the trap. Again, the ABCs of
trap installation should be followed:
Accessible.
Below the point being drained.
Close to the drain leg as possible.
If the trap is too close to the floor to allow the use of a ball
float trap, an inverted bucket trap should be considered. For
additional installation recommendations, see pages LD-50 to
LD-52.

How to Select and Size Armstrong Drain Traps
For Draining Liquids From Gases Under Pressure
Armstrong liquid drain traps are offered in a wide variety of
sizes and types to meet the most specific requirements. The
most widely used models and sizes utilize bodies, caps and
some operating parts that are mass produced for Armstrong
steam traps. The proven capabilities of these components,
along with volume production economies, enable us to offer
you exceptionally high quality at attractive prices. You can
choose the smallest and least costly model that will meet
your requirements with confidence.
Selection Procedure for Draining Liquid From Gas
1. Multiply the actual peak liquid load (lbs/hr) by a safety
factor of at least 1-1/2 or 2. See paragraph headed
“Safety Factors.”
2. From Orifice Capacity Chart LD-12, find the orifice size
that will deliver the required cold water capacity at the
maximum operating pressure. If a light liquid is to be
drained, convert light liquid capacity in lbs per hour to
water capacity using factors in Table LD-5. Then find
orifice size from Chart LD-12.
3. From the Orifice Size Operating Pressure tables on the
product model pages, find the drain trap(s) capable of
opening the required orifice size at a specific pressure
(and specific gravity if other than cold water–specific
gravity 1.0).
NOTE: If specific gravity falls between those shown in the
tables, use next lower. Example: If specific gravity is 0.73,
use 0.70 gravity data.
Liquid Drainers
Safety Factors
Safety factor is the ratio between actual continuous discharge
capacity of the drain trap and the amount of liquid to be
discharged during any given period. Chart LD-12 shows
the maximum continuous rate of cold water discharge of
the drain trap. However, you must provide capacity for
peak loads and, possibly, lower-than-normal pressures. A
safety factor of 1-1/2 or 2 is generally adequate if applied
to the peak load and the minimum pressure at which it
occurs. If the load discharge to the trap is sporadic, a higher
safety factor may be required. Contact your Armstrong
Representative for details.

Selection Examples
EXAMPLE No. 1: Find a drain trap to drain 1,000 lbs of
water per hour from air at 500 psi pressure differential.
Table LD-14, page LD-37, shows the No. 32-LD drain trap
with #38 orifice will operate at pressures up to 489 psi and,
therefore, is suitable for the job. Further checking shows
the No. 2313 HLS drain trap with a 7/64" orifice could also
handle the job, but it is designed particularly for low gravity
liquids and is more costly than the No. 32-LD, so the No.
32-LD is a better choice.
EXAMPLE No. 2: Find a drain trap to drain 6,400 lbs/hr
(safety factor included) of .80 specific gravity liquid from gas
at 400 psi pressure differential.
Since Capacity Chart LD-12 is based on water capacity, the
known light liquid capacity requirement must be converted
to its equivalent water capacity with the factor given in Table
LD-5: 6,400 x 1.12 = 7,168 = water capacity required for
using Chart LD-12.
Chart LD-12 shows that 7,168 lbs/hr and 400 psig calls for
a 7/32" orifice. Entering the .80 specific gravity column of
Table LD-14, page LD-37, shows that a No. 36-LD forged
steel drain trap will open a 7/32" orifice at pressures up to
707 psi. As a matter of fact, this drain trap will open a 1/4"
orifice at 501 psi and would be the one to use.
NOTE: While drain traps are sized on the basis of pressure
differential, steel must be used whenever gauge pressure in
the drain trap exceeds 250 psig.
Where Not to Use
Float type drain traps are not recommended where heavy
oil, sludge or considerable dirt are encountered in lines. Dirt
can prevent the valve from seating tightly, and cold oil can
prevent float traps from opening. Where these conditions
exist, Armstrong inverted bucket BVSW traps should be used.
How to Order Drain Traps
Specify:
•Drain trap size by number
•Orifice size
•Pipe connections—size and type
•Maximum operating pressure
If the correct drain trap cannot be determined, tell us
capacity required, maximum pressure, and SPECIFIC
GRAVITY of liquid.

Multiply 1,000 lbs/hr by 2 (if not already done) to provide
a safety factor; thus, a 2,000 lbs/hr continuous discharge
capacity is required. In Capacity Chart LD-12, the 2,000 lb
capacity line intersects the 500 psi pressure line directly
below the No. 38 drill orifice curve. This orifice is available
in the No. 1-LD or No. 11-LD drain trap, but for much lower
pressures. Moving to the 32-LD, a #38 orifice is good to
489 psi. This is the trap/orifice combination to use.

3. Inspect the tables on pages LD-47
and LD-48 to find the smallest trap
that can open the predetermined
orifice size at the maximum operating
pressure differential. Do not
oversize dual gravity drain traps.
Oversizing will cause excessive
fluctuation of the interface between
the two liquids.

CAPACITY, LBS / HR
2. From Capacity Chart LD-12,
find the intersection of actual
load times safety factor and the
minimum operating pressure
differential. Follow the pressure
line immediately above this point
to intersect the next higher orifice
capacity curve. Then follow this
curve downward and to the left to
get the orifice size.

1-LDC—A See-Thru Body So You’ll Know When It’s Working
Benefits You Can See
Reduced maintenance
Efficient operation
Stainless steel internals mean
corrosion resistance and reduced
maintenance.
Simple ball float mechanism
discharges only when liquid is
present so it doesn’t waste air.
Positive seating
An inside look
Free-floating valve mechanism
assures positive seating so it
prevents air loss. There are no
fixed pivots to wear or create
friction, and wear points are
heavily reinforced for long life.
See-thru body means you can
observe changing conditions
as they occur. See a problem
in the making—instead of
having to deal with it after
the fact.
In-line repairability
Corrosion resistance
Liquid Drainers
In-line connections and
an O-ring seal make for
quick, easy repairs without
dismantling piping. Just
unscrew and remove the body
for maintenance.
502
LD-31
Long-lasting polysulfone
body and reinforced nylon cap
weigh less than 20% of cast
iron liquid drain traps. Rugged
polysulfone resists corrosion
and provides long, trouble-free
service life.
Reduced need for
cleaning
Recessed dirt pocket gives dirt
a place to accumulate away
from the valve seat. Valve seat
is 1-1/4" above the dirt pocket.
Compared to other ball float
drain traps, the Armstrong 1-LDC
reduces dirt fouling and needs
less frequent cleaning.
Simplified installation
Optional horizontal or vertical inlet
with horizontal outlet eliminates
the need for extra fittings. Makes
installation in existing systems easier.
Vertical inlet is 3/4" to accommodate
air venting. Requires no electricity.
NOTE: The Armstrong 1-LDC is not recommended for extremely dirty systems or those with heavy
oil carryover. The drain trap should not be used in an environment where there are high levels of
ketones or chlorinated or aromatic hydrocarbons.

1-LDC—A See-Thru Body So You’ll Know When It’s Working
Now, you can literally see what you’ve been missing—the early warning
signs of a drain trap or system problem. Since you’ll know the operating
condition of a drain trap, you won’t waste time and money scheduling
maintenance that isn’t needed. In other words, you will be able to react to a
condition before it becomes a problem.
Moisture in a compressed air system causes a variety of problems—
everything from dirt fouling and potential corrosion to water hammer. Getting
the water out—automatically, reliably—builds greater efficiency into
your system. In short, pay attention to your compressed air system, and
you’ll probably pay less to compress air.
A simple ball float mechanism requiring no electricity to operate, the new
Armstrong 1-LDC discharges automatically only when liquid is present.
That means no air loss as with timed devices, which open even when liquid
is not present.
Compare…and Save the Difference
Seeing really is believing—especially when you compare the Armstrong
see-thru drain trap with cast iron units. Measure the differences in the
time and money you can save with a more efficient, easier-to-maintain
compressed air system. For more information or technical assistance,
contact your local Armstrong Representative.

1-LDCW See-Thru Air Liquid Drainer for Ozone Applications
For Pressures to 150 psig (10 bar) or Specific Gravity 1.0
What Is Ozone?
Ozone is a gas that forms naturally during thunderstorms when
lightning converts normal oxygen molecules (O2) into ozone (O3).
The fresh, sweet smell in the air after a storm is the smell of ozone.
The unstable ozone molecule reacts rapidly with most substances
and is an extremely strong natural oxidant.
How Is Commercial Ozone Produced?
Ozone can be formed by exposing air to ultraviolet light; however,
the most common method of generating ozone is by passing
air through an electrical discharge. Because ozone has strong
oxidizing properties, its production requires corrosion-resistant
equipment.
How Is Ozone Used in Water Filtration and Purification?
Because ozone is such an effective oxidant, it kills viruses, bacteria,
mold, mildew, fungus and germs. Passing ozone through water
achieves high purification rates without any chemical residue.
Oxygen is the only by-product.
1-LDCW
Typical Customer Applications:
•
•
•
•
Purifying standing ground water in Third World countries.
Conditioning water for poultry and livestock.
Purifying water in the bottled water industry.
Filtering and purifying water for process applications.

NOTE: If specific gravity falls between those shown in the chart, use the next lower gravity. For example, if specific gravity is 0.73, use 0.70 gravity data.
High Temperature Service
Maximum allowable working pressures
of floats decrease at temperatures
above 100°F (37.8°C). Allow for approximately:
• 10% decrease at 200°F (93.3°C)
• 15% decrease at 300°F (148.9°C)
• 20% decrease at 400°F (204.4°C)
The float is not always the limiting factor, however.
Consult with Armstrong Application Engineering if you
have a high-temperature application that also requires

Free Floating Lever Drain Traps
For Loads to 49,000 lb/hr (22,226 kg/hr)...Pressures to 300 psig (21 bar)
Armstrong’s cast iron, free floating lever drain traps use the
same bodies, caps, lever mechanisms, valves and seats of
Armstrong inverted bucket steam traps that have been proven
in years of service. Elliptical floats and high leverage make it
possible to open large orifices to provide adequate capacity
for drain trap size and weight.
List of Materials
2-LD, 3-LD and 6-LD cast iron traps are identical in design,
materials and workmanship to those for saturated steam
service up to 300 psig (21 bar) with the exception of the
addition of a guidepost to assure a positive, leaktight valve
closing under all conditions.

Fixed Pivot and Snap Action Drain Traps
For Loads to 3,900 lb/hr (1,769 kg/hr)...Pressures to 1,000 psig (69 bar)
Continuous Flow or On-Off Float Type Drain Traps
No. 71-A—Wide open, tight-shut drain trap for use where
fine dirt and grit may be present or where liquid load is light.
A flat spring in the leverage system holds the valve closed
until the trap body is nearly full of water. Then it snaps
open, washing dirt through. When the trap body is nearly
empty, the spring snaps the valve shut.
Armstrong’s line of fixed lever and snap action drain traps
includes two basic models available in cast iron and forged
steel. The floats are light enough to handle light liquids.
No. 21—A small, high-quality, economical drain trap for use
on drainage jobs where dirt and oil are not encountered. It
employs a single lever with a fixed pivot.
No. 71-315—Forged steel version of No. 71-A.
CAUTION: Ball float drain traps are not recommended
where heavy oil, sludge or considerable dirt are encountered
in lines. Under these circumstances use Armstrong inverted
bucket BVSW traps.
No. 21-312—Forged steel version of the No. 21 with larger
float and higher leverage.

LD-44
High Leverage Spring-Loaded Ball Float Type Drain Traps
For Low Flows at Pressures to 3,700 psi (255 bar) and Specific Gravity Down to 0.40
The Armstrong High Leverage Series of liquid drain traps
was developed especially for draining low specific gravity
fluids from gases at high pressures. They use standard
Armstrong forged steel bodies with very high leverage
systems and spring assist.
Sour Gas Service
Forged steel and stainless steel traps can be modified
to resist hydrogen sulfide stress corrosion. These
modifications involve annealing the float, which will reduce
the maximum working pressure of the float to about half its
normal value. Consult Armstrong Application Engineering
for allowable working pressures.
NOTE: Models 2313-HLS, 2316-HLS, 2413-HLS and
2415-HLS are also available with cast T-316 stainless steel
body and all-stainless steel internals. Consult factory.
Table LD-26. Reference Data
Because of design considerations in this drain trap, it is
essential that a safety factor of at least 2 be applied to the
peak liquid load for sizing purposes.

Free Floating Lever Dual Gravity Drain Traps
For Pressures to 1,000 psig (69 bar)
Armstrong free floating lever dual gravity drain traps are
identical to the units described on pages LD-38 and LD-40
except float weights are modified to make them suitable for
draining water from a light liquid. If you wish to use them
for draining any liquid with specific gravity other than 1.00,
consult the Armstrong Application Engineering Department.
Floats for dual gravity drain traps are weighted with
quenching oil which, in the unlikely possibility of float failure,
may be dispersed through the system. If this is a hazard,
consult the Armstrong Application Engineering Department.
Viscosity Considerations for Dual Gravity Traps
The operation of dual gravity traps depends upon a float
that will sink in the light liquid and float in the heavy
liquid. When the specific gravities of the two liquids are
very close, the available operating forces are, therefore,
also very small. Viscous fluids may impair the ability of
the trap to respond to changing liquid levels.
Consult Armstrong’s Application Engineering Department
if your application involves fluids more viscous than 70 cs,
which is approximately the viscosity of a light machine oil.
NOTE: Armstrong can design dual gravity traps for venting
light liquids from above heavier liquids. Consult the
Armstrong Application Engineering Department.

Installation and Maintenance of Drain Traps
For Draining Liquid From Gas...for Draining Water From Light Liquid
Installation Procedures
Pipe Fitting. Adhere to good piping practice. Clean pipes
carefully after cutting and threading before hooking up traps.
Before connecting traps to system, blow down at full pressure
to clear the pipes of dirt, pipe cuttings and other foreign objects.
Strainers are necessary if there is a chance scale and
sediment can be carried to the trap.
Blowdown Valves may prove useful.
Shutoff Valves & Unions should be provided so the drain
trap can be examined and/or serviced without shutting down
the unit drained.
Drain Traps on gas and other critical applications should be
checked at the same time valves and other line equipment
are inspected. Your own experience will determine the
required testing schedule.
Troubleshooting
A. Drain trap does not discharge.
1.Insufficient liquid coming to drain trap to permit
discharge. Continue operation.
2.Drain trap filled with dirt or sludge. Remove cap and
mechanism; clean thoroughly. Install strainer in inlet
side of drain trap.
3.Differential pressure across drain trap too high. Check
inlet and outlet pressure. If the difference exceeds the
maximum operating pressure stamped on the drain
trap, the valve will remain closed. Reduce differential
pressure if possible, or install properly sized mechanism
in drain trap if possible.
4.Worn valve seat. As the seat becomes worn, the
seating surface area enlarges, lowering the trap’s
maximum operating pressure. Replace with new parts.
5.Inlet or outlet line valves closed. Open valves.
6.Strainer clogged. Clean strainer screen.
7.Float defective or collapsed. Replace float.
Operation. Maximum operating pressure is stamped on the
trap. Do not exceed this pressure.
A. Ball float drain traps must be located below the drain
point.
B. Make inlet piping as short as possible with a minimum of
elbows and other restrictions.
C. Back venting usually required on ball float drain traps.
1.Pressure vessels should be vented back to any
convenient point above the liquid level. Use a fullported valve in the back-vent line. On larger traps (6
and 36-LD and larger) use a minimum of 3/4" (20 mm)
nominal pipe for back venting—1" (25 mm) or larger
preferred for heavy loads. Remember, the pressure in
the unit drained and in the drain trap are the same—
only the difference in liquid levels produces flow.
2.Separators and drip points should be vented to the
downstream side of the unit.
3.On very light loads, venting is not necessary, but use
at least a 3/4" (20 mm) connection between the vessel
and the trap. Make sure inlet line is vertical or pitched
to trap.
4.Float type drain traps do not require priming.
B. Drain trap discharges continuously.
1.If drain trap discharges full stream of liquid continuously
and vessel fills full of liquid—
a.Drain trap too small for job. Replace with correct size.
b.Abnormal amounts of liquid coming to drain trap.
Remedy cause or replace with drain trap that has a
larger capacity and will handle peak loads.
C. Drain trap blows through.
1.Dirt or scale on valve or seat. Remove cap, clean
drain trap, as well as valve and seat.
Drain Trap Testing and Troubleshooting
3.IB trap may lose its prime.
a.Close the inlet valve for a few minutes. Then
gradually open. If the drain trap catches its prime, the
chances are that the trap is all right.
b.Frequent loss of prime may require an internal check
valve or, if trap is old, valve and seat may be worn.
Testing Schedule
A regular schedule should be set up for testing and
preventive maintenance. Size and operating pressure
determine how frequently drain traps should be checked.
Units on normal industrial applications should be checked
as follows:
High Pressure Drain Traps—250 psig (17 bar) and up.
Test daily to weekly.
2.Worn valve, or seat that is wire-drawn. Remove cap,
replace mechanism.
Liquid Drainers
Typical installations of drain traps are shown in drawings in
“Installation and Maintenance of Drain Traps” section.
In the event of any unusual maintenance or operational
difficulty, consult your Armstrong Representative, or the
Armstrong International Application Engineering Department.
Medium Pressure Drain Traps—60 to 250 psig (4 to 17
bar). Test weekly to monthly.
Low Pressure Drain Traps—1 to 60 psig (0.07 to 4 bar).
Test monthly to annually. Large traps on high capacity jobs
can be tested more frequently to good advantage.

Installation and Maintenance of Drain Traps
For Draining Liquid From Gas...for Draining Water From Light Liquid
Installation of Armstrong drain traps for the most satisfactory
operation requires that a few simple rules be observed:
Priming. Prime bodies of inverted bucket drain traps before
turning on the air. Ball float traps do not require priming.
Clean Piping. First install piping and valve ahead of trap,
then blow down at full air pressure to remove loose dirt. Last
of all, screw the trap into position.
Back Venting (Ball Float Traps Only). Ordinarily a drain
trap has little water to handle, and a single line to the top
of the trap is sufficient. However, if a ball float trap must
be installed at some distance from the drip point, or if there
are large quantities of water to be discharged, back venting
is good insurance for positive and fast flow of water to the
drain (See Fig. LD-52). Be sure there are no pockets in the
vent line in which water could collect and prevent venting
(See Fig. LD-54). If high water level is objectionable, raise
the receiver, or dig a pit so top of trap can be at the same
level as the bottom of the drain line (See Fig. LD-53).
Otherwise, use an inverted bucket trap that can be installed
above the drip point (See Fig. LD-49).
Liquid Drainers
Location. Compressed drain traps should be located below
and close to the unit being drained (See Figs. LD-48 and
LD-50), or as directed by the equipment manufacturer.
When headroom is inadequate, inverted bucket drain traps
can be installed above the unit drained, but they must be
equipped with a check valve in the inlet line (See Fig. LD-49).
They should be accessible for maintenance.
Figure LD-48.
Standard hookup for inverted bucket
drain trap BVSW. Be sure to fill trap
body with water before opening the
valve.

LD-51
Figure LD-49.

installation below the receiver. Note trap should either have internal check valve
or a swing check to prevent prime loss when air pressure drops.

Do not install a ball float trap above the drip point or put a
loop or pocket in the line to the trap. The water seal prevents
air from leaving trap body and allowing liquid to enter.

Flo-Rite-Temp Instantaneous Steam/Water Heater has
a unique feed forward design which features a differential
pressure diaphragm actuated mixing unit integral to a shell
and tube heat exchanger.
®
The Flo-Rite-Temp mixing unit manages the water flow
through the heat exchanger based upon downstream
hot water demand and eliminates the requirement for a
modulating steam control valve.
Flo-Rite-Temp Instantaneous Water Heater
Operating on constant low pressure (2-15PSI) steam, the FloRite-Temp mixing unit supplies water to the heat exchanger
where it is overheated and then returned to the mixing unit
for proportional re-mixing with cold water to a pre-set outlet
temperature.
Speed of Response – a differential pressure diaphragm
within the mixing unit rapidly responds to a change in system
demand and significantly reduces the lag times typically
associated with feedback/modulating steam control valve
systems.
®
Failure Safe - Flo-Rite-Temp mixing valve has a diaphragm
actuated design which can be described as "failure safe".
In the event of a diaphragm failure the mixing unit will fail
with a cold bias and will not allow hot water to exit the heat
exchanger.
Flo-Rite-Temp Instantaneous Water Heater
Pre-Piped Packaged Solution with The Brain®
Digital Recirculating Valve
Temperature Control and User Safety - capable of
controlling outlet temperatures +/-4°F, this principal of
operation offers the additional relevant benefit of reducing
the waterborne bacterial content of the water during the
overheating process. In addition, with no water storage
®
requirement, Flo-Rite-Temp water heaters are a sensible
selection as a component of a broader system design
initiative for Legionella risk reduction.
Ease of Installation - no storage tank, small footprint, access
via a standard doorway and pre-piped packaged solutions
reduce installation time, space and expenditure.

Flo-Direct Complete Thermal Exchange Gas Fired
Water Heater
®
CTE Technology
Developed from direct contact water heating science which was
first introduced more than two decades ago, Complete Thermal
Exchange (CTE) technology has revolutionized high efficiency water
heating methods. Today CTE enjoys a proven record and has rapidly
become the new standard in high efficiency water heating and energy
savings.
While traditional direct contact water heating can offer significant
energy savings when compared to a conventional steam boiler
®
system, the Armstrong Flo-Direct CTE gas fired water heater offers
an unparalled, 99.7% high heat value (110% approx. low heat value)
efficiency rating* throughout each phase of its operation cycle.
The sustained operational efficiency of Flo-Direct® CTE gas fired
water heaters creates the most energy efficient method of hot water
production currently available.
No Scale Build-Up
The Flo-Direct® CTE gas fired water heater’s unique design prevents
scale build-up because there are no “hot spots” internally or
externally, and because calcium is prevented from completely falling
out of suspension during operation. As a result, the mineral content of
the influent water and the effluent water will be equal.
®
Armstrong Flo-Direct CTE gas fired water heaters
achieve CTE Standards
The Flo-Direct® CTE direct contact water heaters, meet five
standards not available with the older designs and traditional
methods of direct contact water heater technology:
1. CTE units maintain a minimum of 99.7% high heat value (110%
approx. low heat value) efficiency in all modes of operation, not
just under optimal conditions.
2. CTE units have multiple thermal passes. Water and the
combustion gasses (or heat from the combustion) repeatedly
come in contact. This ensures that the maximum amount of heat or
energy from combustion is transferred to the water.
3. CTE units have a dry combustion chamber. This is vital to
maintaining complete combustion at all times during operation.
4. CTE units maintain complete combustion at all times.
5. CTE units must have an integral water quality integrity system.
Operational procedures must be in place to ensure that effluent
water quality is equal to the influent water quality.
While many traditional-method direct contact water heaters spray
water directly on the flame – sometimes called “flame quenching” –
Flo-Direct®, using CTE technology, avoids this process altogether.
According to the Industrial Heating Equipment Association’s
“Combustion Technology Manual,” flame quenching promotes
incomplete combustion, and produces alcohols, aldehyde, formic
acid, higher order acids, carbon monoxide, as well as carbon
dioxide and water vapor. With CTE technology, Flo-Direct® maintains
99.7% high heat value* (110% approx. low heat value) combustion
efficiency, while maintaining water quality at all times.
Flo-Direct® Complete Thermal Exchange (CTE) Gas Fired Water
Heating Technology significantly limits the effluent water chemical
additives typically attributed to other process water heating
systems.
Our unique CTE water heating process deaerates the water
significantly. Independent third party testing has verified CTE
technology can actually remove some chemical constituents from
the influent water.
NSF test results show that the effluent water from a Flo-Direct
CTE Gas Fired Water Heater meets US, European Union and
PRC bottled drinking water standards* and has been tested and
documented as fully compliant with:
• USFDA - The United States Food and Drug Administration, Code
of Federal Regulations Bottled Water Standard: Chapter I, Title
21, Part 165, Subpart B, Section 165.110.
• EU-TRW - The European Union Directives(s) - Treated Waters:
98/83/EC.
* Peoples Republic of China Standards for Drinking Water:
GB5749-2006
Industrial Hot Water
Complete Combustion = Complete Water Quality
Global Water Quality Standards
*Statement presumes influent water also meets listed standards.
*See page 530 for high heat value (HHV) and low heat value (LHV)
explanation.

Steamix Hose Stations will not pass live steam in the event
of:
•a significant cold water pressure reduction.
•a complete failure of the cold water supply.
•mechanical failure of its primary operating component.
STEAMIX Hose Stations are designed to improve efficiency
and reduce risk when mixing STEAM and WATER for
washdown. When your process demands high washdown
temperatures, adjusting the mix of steam and water becomes
much more difficult and dangerous. With the older style,
dual globe valve Mixing “Y,” it is easy to introduce too much
steam — with dangerous consequences for your personnel Not with STEAMIX!

valves and pipes, and cause other problems.
L
L
Armstrong drain separators separate condensate efficiently
by using the centrifugal force of steam or air created by
introducing it into a specifically shaped path. Because of
the simple structure of the drain separators, pressure loss
is minimized, enabling clean, dry steam or air to be fed to
equipment.
With correct sizing and proper drainage, the separators
are designed to eliminate 98% of all entrained liquids and
particles that are 10 microns and larger in size.

Operating Principle
When steam or air flow enters the drain separator, centrifugal
force is generated in the fluid because of the device’s internal
structural design. The fluid drains along the wall because of
the difference in specific gravity with steam or air, eventually
striking the baffle. The baffle guides the fluid to the drain
outlet and to the trap, which drains it. As a result, both small
dirt particles and condensate are separated and removed
from the system through the bottom drain.

Stainless Steel Sump Ejector
Armstrong Condensate Management Group offers a
stainless steel sump ejector for use in draining unwanted
water from steam pits, steam tunnels or enclosed spaces.
The stainless steel sump ejector uses a snap-acting Inconel
X-750 spring-assisted mechanism, which engages a steam
motive valve, turning the pump on or off as the float rises
and falls. The all stainless steel design will ensure long life
in the rather harsh environment of a steam pit.
The stainless steel sump ejector is designed to eliminate
maintenance headaches and safety issues surrounding
steam pits, tunnels and enclosed spaces.
Features
•All stainless steel construction and design guard against
corrosion
•True steam-on, steam-off operation
•Heavy duty Inconel X-750 springs provide a long, troublefree service life
•The small, compact and unique cast stainless steel design
is unlike anything on the market today

CC Series Condensate Coolers
Drain Tempering Service
Description
$
Armstrong’s Condensate Cooler is a device that mixes hot condensate
or hot water with a cold water supply to reduce the temperature to
acceptable discharge drain temperatures as required by city and
state codes. It is a pre-assembled package that is suitable for any
plumbing system. When hot condensate or hot water is drained into
the condensate cooler body, the tempering valve opens and allows
cold water to enter the chamber and mix with hotter liquid, cooling
it to a preset temperature level of 135°F (57°C) or to a desired field
set temperature.

Where: B = Set point of tempering valve (preset to 135°F)
C = Cold water temperature
H = Hot water temperature or condensate temperature
Example:
(135 - 50)
x 5 (CC-5) = 3.25*
(180 - 50)
3.25 gal x 8.33 lbs per gallon x 60 = 1,624 lbs per hour
*In the example, Model CC-5 (5 gpm) can handle 3.25 gpm of 180°F liquid.
If cold water temperature or discharge temperature changes, the capacity
will change.

Armstrong MS-6 Noiseless Heater
The use of hot water is indispensable in food processing,
cleaning, and plating operations. Although the simplest
and most efficient way to provide the water is by direct
steam sparging, such a format often results in vibration and
noise caused by steam blowing into the water tank. These
problems can be greatly reduced by mounting an MS-6
noiseless heater at the end of the pipe.
Features
•Stainless steel construction for greater durability
•Mounting is simple and economical
•Maintenance free

Armstrong University Energy Seminar
Knowledge Not Shared Is Energy Wasted®
Since Armstrong designed and manufactured its first steam
trap in 1911, we’ve solved virtually every imaginable problem
in steam trapping and steam humidification. In the process
we’ve accumulated a substantial body of information. It’s
practical know-how, not just theory. And for years we’ve
shared this knowledge with anyone interested. We go
to great lengths to share what we know because we’re
convinced that this kind of interaction is the best way
to solve problems, meet individual needs and maximize
the return on your energy investment.
Steam Energy Seminars are held at Armstrong’s manufacturing
headquarters in Three Rivers, Michigan. Armstrong also
operates seminar facilities in Liege, Belgium, Chennai, India,
and Beijing, China.
With the help of sophisticated sound and projection
equipment and an elaborate working model of a steam
system with live steam and glass piping, you’ll see how
different types of steam traps perform under various
conditions.
Starting With the Basics
At an Armstrong University Energy Seminar, you’ll learn
how to cash in on long-term labor, material and energy
savings. Starting with the basics, you’ll review the fundamentals
of steam.
Your Armstrong instructors have both the technical background
and the field experience to make information relevant.
Understandable. With their help, you’ll walk step-by-step
through the installation, operating/energy characteristics
and maintenance of all kinds of steam traps.
In short, you’ll learn about savings. Not as some loosely
defined goal, but as hard, no-nonsense gains you can
measure on a year-end chart.
Topics such as corrosion, water hammer and thermal stress
will be discussed. And because each seminar can be tailored
to your specific interests, special topics of individual concern
may also be covered. Tell us what you want to know, and
we’ll emphasize it for you.
Sessions are informal, with plenty of chances to participate and
ask pointed, specific questions. (If you desire, a presentation
can be tailored to your specific needs.) You’ll also be able to
listen to the questions and problems of others in the industry
and discuss how their solutions may benefit your steam
system.
At Armstrong University, there’s no pressure selling. Basic
information is presented honestly. And the demonstrations
speak for themselves. We are here to build relationships
with our customers.
You will also examine how steam trap selection, sizing and
installation bear on energy consumption, downtime and
maintenance. What’s more, you’ll review the guidelines for
trapping steam distribution systems, tracer lines and various
types of heating, process and heat exchange equipment.

Reference Guide to Armstrong’s Training Aids
Classroom Training Aids
Training for Energy Conservation
In a survey of plant engineers, plant managers and key
maintenance engineers, 89% said that there will be a
greater need for training in the years ahead. One of the
primary areas of training will be in the arena of steam
system maintenance because of the great potential to
save energy and money.
Since building its first steam trap in 1911, Armstrong
has been committed to sharing information and technical
knowledge on steam energy conservation. Armstrong not
only shares this information with its Representatives, but
for years it has conducted seminars for its customers.
Seminars have been conducted in our facilities as well
as in customers’ plants.
To extend its training program further, Armstrong assists
many companies in developing their own in-house training
activities. This guide is published to inform these trainers
of the educational resources available from Armstrong.
Many of the training aids are available at no charge. Other
resource materials are available at a nominal charge. These
items are marked with a dollar sign ($). For prices, contact
Armstrong’s Marketing Department.
Armstrong offers an extensive list of handbooks, catalogs
and bulletins covering a wide range of topics. Some of
these publications provide valuable resource material for
classroom instruction.
Armstrong also provides many other training aids to help
trainers conduct programs on various aspects of steam
system operation and maintenance. Following are some
of the materials for planning and implementing an effective
steam system maintenance program.
Line Card 320 with Catalog CD-ROM: Line Card 320
includes a CD-ROM of Armstrong’s catalog, Solution Source
for Steam, Air and Hot Water Systems. The CD also features “Steam Conservation Guidelines for Condensate
Drainage,” which is recognized as one of the most authoritative discussions on steam, steam traps and steam
energy conservation available today.
•
Let’s Talk Steam Traps/Update is a two-part,
32-minute DVD that discusses the operating principles of mechanical, thermostatic and
thermodynamic steam traps. Designed to be used
in conjunction with the Conservation Guidelines
section of this catalog, the DVD discusses 10 steam
system operating conditions that must be considered in evaluating steam trap performance. $
• Guidelines for Steam System Efficiency is a
15-minute educational program covering basic
considerations in the design, piping and trapping of steam systems. Topics covered in the DVD include correct sizing and installation of steam supply and condensate return lines, steam velocities in the
system, the use of air vents, vacuum breakers and safety drains, and much more. This DVD stresses how low energy, maintenance and
operational costs in your system can be achieved
by proper design, installation and maintenance. $
• Guidelines for the Prevention of Water Hammer
is a 16-minute DVD explaining three types
of conditions that cause water hammer. The damaging
effects of water hammer to steam system components
also are described. Recommendations are made
in the DVD on the proper trapping and piping to
reduce the potential for water hammer. The results
of reducing or eliminating water hammer are a safer
work environment, lower maintenance costs and
reduced system downtime. $
Steam-A-ware™ Sizing and Selection Software: Proper
sizing and specifying of steam traps, pressure reducing
valves and water heaters is critical in order to save energy
and extend equipment life. For users, this has continued to
be a confusing and complex process. Now the easy-to-use
Armstrong Steam-A-ware software program for sizing and
selecting steam traps, pressure reducing valves and water
heaters can be downloaded from Armstrong’s Web site,
armstronginternational.com.
Service, Training
and Warranties
Sectional Models: Being able to see inside steam traps
has been effective in helping people who work with traps to
understand how they operate. Armstrong offers more than a
dozen different sectional models of its steam traps and related
products. Also available are glass traps, which allow students
to view the operation of various steam trap types. $
DVDs: While Armstrong has more than a dozen

speaker for your employees.
Continuing Education Aids
“Knowledge not shared is energy wasted ® ” is a philosophy
of Armstrong, and the company is dedicated to the premise
of sharing knowledge on a continuing basis. Furthermore,
knowledge not applied is knowledge wasted. For example,
a person may learn the techniques of testing steam traps
in a classroom setting, but if it is not applied, the skill is
quickly lost. Following are some training aids involving
hands-on experience that are useful on a day-to-day basis.
Reprints: Sharpen Trap Testing Skills to Save
Maintenance Hours and Conserve Energy is a reprint
from POWER Magazine. It was authored by Armstrong’s
technical staff, including engineers and research staff members. It stresses the importance of individual training and
plenty of practical experience. The article also includes a

What Is Steam?
15:07 Minutes
This is the basics-of-steam primer… the “Steam 101”
short course on the principles of steam that leads to a
thorough understanding of the concepts outlined in the
many Armstrong training DVDs and materials. Both live
action video and clear, simple animation are used to
illustrate steam properties and behavior. Everyday
demonstrations and a straight-forward style help make
this an informative and entertaining DVD, whether used
as an introduction or as a refresher.
Guidelines for Steam System Efficiency
15:17 Minutes
This educational program covers basic considerations in
the design, piping and trapping of steam systems. Topics
include correct sizing and installation of steam supply and
condensate return lines; steam velocities in the system;
proper steam trap installation; trap safety factors; the use
of air vents, vacuum breakers and safety drains; and how
non-condensables affect the performance and service life
of heat exchanger equipment.
Guidelines for the Prevention of Water Hammer
16:15 Minutes
The purpose of this educational tool is to help customers
understand the nature and severity of the water hammer
problem.
Using live action video and computer animation, this program identifies the most likely causes of water hammer and
provides solutions that can be implemented to prevent its
occurrence. With a better understanding of the problem,
more preventive measures and equipment can be designed
into new or existing installations. The results will be safety
for personnel, lower maintenance costs and reduced system
downtime.

Let’s Talk Steam Traps/Update
32:00 Minutes
Part one uses animation techniques to help viewers see
and understand the operating principles of the three types
of traps: mechanical, thermostatic and thermodynamic. In
addition, the DVD helps steam trap users understand the
internal
operation of inverted bucket steam traps, differential condensate controllers, float and thermostatic traps, thermostatic traps, and disc traps.
570
The second part of this 32-minute DVD discusses
10 steam system operating conditions that must be considered in evaluating steam trap performance. The five types of
traps are then rated on how they respond to these 10 different operating conditions.
Guidelines for Steam Trap Troubleshooting and Testing
18:40 Minutes
Just as properly functioning steam traps contribute to
the efficient operation of a steam system, those that are
malfunctioning can result in lost steam, lost heat and,
especially, lost dollars. Guidelines for Steam Trap
Troubleshooting and Testing not only outlines the need
for establishing a preventive maintenance program, but
details what to look and listen for in your testing.
This DVD recommends a step-by-step approach plant energy technicians can take to steam trap testing and problem
solving. It emphasizes use of the faculties of both sight and
hearing in gathering information, then applying training and
experience to properly evaluate the results.
The Anatomy of the I.B.
15:00 Minutes
The Anatomy of the I.B. uses production techniques to look
inside the inverted bucket steam trap. This DVD uses both
cell animation and an operating glass-bodied model of an
inverted bucket steam trap to show its components and
observe its performance.
Guidelines for Unit Heater Efficiency
9:44 Minutes
Every winter industry relies on unit heaters to provide a
comfortable environment for workers. The heating season
is no time for the nuisance and discomfort of unit heater
repair or replacement.
This video program discusses how correct selection,
installation, and maintenance of steam supplied unit
heaters ensures longer service life and reduces
unnecessary repair and replacement costs.
Guidelines for Freeze Prevention
10:52 Minutes
Freezing in outdoor steam systems is a costly maintenance
and production problem. Certain guidelines can be followed
to minimize damage and process interruptions due to freezing. In addition to highlighting these piping and trapping
guidelines, the DVD covers an often overlooked problem
that can prevent total drainage of the system.
Graphics and glass piping illustrate why condensate
remains in or upstream of various types of traps after
steam systems are shut down. The DVD discusses what
can be done to get rid of remaining condensate by the
use of temperature and pressure actuated safety drains.

Armstrong DVDs
It’s the Humidity
Part 1—24:58 Minutes
Part 2—20:57 Minutes
Part one is a video documentary covering the essentials
of humidity and outlining the primary reasons for humidity
control. What is humidity? Relative humidity? What is dew
point? Enthalpy? How does evaporation affect comfort?
How does humidity conserve energy? All of these questions
are answered in practical and entertaining demonstrations.
Part two is a look at the four basic methods of large scale
humidification. Through animation, the DVD discusses
the operation of evaporative pan, wetted element, water
spray and steam humidifiers, and rates their ability to meet
efficiency, maintenance, controllability, sanitation and cost
requirements.
Guidelines for Steam Trap Repair
20:41 Minutes
This DVD begins by outlining a plan for identifying faulty
traps and returning them to effective operation. The first part
of the DVD provides guidelines for the inspection and repair
of any trap.
The second part addresses specific trap types—inverted
bucket, float and thermostatic, disc, and thermostatic. Each
trap requires individual considerations, and attention is given
to the differences as well as the common concerns.
The Armstrong Differential Condensate Controller
18:36 Minutes
To the paper, textile and boxboard industries, proper
condensate drainage from steam heated cylinder dryers is
necessary to optimize production and conserve heat energy.
This DVD discusses the standard steam trap drainage method and the blow-through method of condensate removal.
Let’s Talk PRVs
30:00 Minutes
Pressure reducing valves, or PRVs, are important to the
efficient use of fluids and gases in industry.
Let’s Talk PRVs is an in-depth look at the reasons for,
configurations of, and means of evaluating pressure
reducing valves.
Through animation, the viewer looks inside several different
types of PRVs to gain an understanding of their operating
principles. This understanding will help the viewer select the
right PRV for a particular application.
Guidelines for Steam/Air Coil System Design
13:12 Minutes
This educational video program explains the major causes
of frozen steam coils, and the steps that can be taken to
prevent the problems. The program uses the air handling
system assembled in the Armstrong demonstration lab to
illustrate problems and solutions. Glass piping and glassbodied traps allow viewers to see the flow of condensate
and to witness adverse effects of improper system design,
as well as the benefits of corrective measures.
Guidelines for Ultra Capacity Steam Trap Repair
23:00 Minutes
This DVD begins by outlining a plan to return individual
faulty traps to effective operation. The first part of the DVD
provides guidelines to be followed in the inspection and
repair of any trap.
In the second part, Armstrong’s ultra capacity F&Ts
(Models J, K, L and M) are disassembled, repaired and
returned to service. Both single orifice and dual orifice
variations are covered.
The Armstrong differential condensate controller, the DVD
points out, combines features of both methods, and overcomes the drawbacks of both. The result is efficient removal
of condensate and air, minimum steam loss, and higher and
more uniform temperatures across the dryer surface.
