TWT Deposit Control Installation & Configuration Guide
TWT Deposit Control Installation for Fluid-Fed Equipment - Determining
Points of Treatment and Optimum Treatment Configurations for
Commercial and Industrial Facilities and Systems
A complete TWT treatment system may use all or only some of the components of a comprehensive water treatment plan, including deposit control,
filtration, purification, and disinfection. This configuration guide deals with
factors to consider when selecting TWT deposit control models for use in
a commercial or industrial environment.
Site conditions may indicate that a combination of deposit control products of
varying sizes and models is most appropriate for an optimal installation.
Among the factors to consider are water chemistry (hardness/grain count)
process, “reaction zones”, and pipe layout.
We have established that certain configurations are preferred for certain
uses, and that if correctly installed in these configurations, the TWT Deposit
Control Systems will deliver even greater performance than may have been
previously experienced, providing the best end-to-end fluid management
and treatment solutions available.
The ability of the Triangular Wave Technologies Deposit Control Systems
to inhibit scale and biofilm deposits and to remove preexisting deposits is
dependent upon the proper application and installation of the products
purchased from TWT Inc. Water chemistry must be taken into consideration.
Every application has areas called reaction zones.These areas represent
locations in a system where the fluid is exposed to different types of
changes that affect its behavior.
Mechanical: change in pressure, velocity, direction, flow patter ( pumps,
aerators, agitators, etc.)
As a result of the TWT fluid conditioning, these deposits will be softer and
more easily removed when treated by the TWT deposit control system. In
most cases the heating system process and self cleaning ability will wash
away any potential build up, allowing for a significant reduction in maintenance procedures.
If a heating system can be operated without boiling/flashing on the surface of
the heating element, a significant reduction in deposits will be obtained. As
the fluid temperature is lo wered from boiling, the ability of the TWT-treated
water to hold the deposits in solution increases.TWT recommends
that a reaction chamber and/or onsite wrap be located upstream of
( before) any heating system, and where possible downstream (after) the
heating system, to further ensure the ability of the fluid to retain the deposits
in solution.
When fluid is heavily saturated with deposits (TDS, grain count, change
in concentration/ fluid condition ), the ability of the TWT Deposit Control
System to treat fluids and hold deposits in solution is decreased but not
eliminated. The ability of the TWT Deposit Control Treatment System effectiveness decreases proportionately with the increase in TDS. i.e., grain
count, change in concentrations, evaporation and/or other fluid exposures as
referred in the above“ reaction Zones”. That is why you must examine the
water (fluid ) to be treated and all of the obvious influences surrounding it to
ensure proper installation & application. Under these conditions TWT recommends that you upsize ( increase the oscillating electrical field) the Deposit
Control System to meet and ensure the highest level of performance for these
For these and other special requirements and installations, TWT, Inc.,
Representatives, Dealers and Distributors will work directly with you to
custom design fluid management solutions and system c o n f i g u rations fo r
your industry-specific needs in an operational and effective manner.
Thermodynamic: changes in temperature ( heat exchangers, evaporators,
boilers, spray nozzles, etc.)
Physicochemical: change in concentration, state (memb ranes, cooling
towers, filters, main/makeup water inlets, etc.)
It is in the reaction zones where the particles in the fluid, due to the
changes to which they are exposed, are more likely to form scale or biofouling.There are many systems, which, due to their nature, will have multiple
reaction zones. In general, it is the reaction zone(s) where the TWT Deposit
Control treatment should be focused. In these cases, the size and condi tions of the system will play an important role in determining the need for
one or multiple units, likely of varying sizes/models. (based on pipe size and
material )
Our suggested considerations for optimal installation of the
TWT Deposit Control System:
The Deposit Control System will provide the means to keep deposits
(calcium, lime, etc.) in solution for extended periods, if not disturbed.
The ability of the fluid to retain the deposits in solution is decreased ( but not
eliminated) by fluid disturbances (e.g., pressure changes) high temperature
conditions ( flashing, boiling, etc.) and changes in concentration
(fluid conditions).
In Automatic Fill Systems, a Fill Solenoid Valve/Float Valve will be used to
control the fluid level in the fill system. Where a large pressure change
takes place immediately downstream of the valve, TWT recommends that
the Reaction Chamber an d/ or the on-site wrap be located downstream from
the valve to avoid this pressure change point.When water boils and/or is
evaporated, the calcium and other dissolved solids remain and form deposits.
TWT Factory Wrapped Reaction Chamber
The Triangular Wave Deposit Control System creates an electromagnetic
field which is used to address the fluids in the pipe. Do not install the wire
coil on any magnetic pipe, such as STEEL, GALVANIZED STEEL, IRON,
DUCTILE IRON OR CAST IRON. When the coil is applied to a magnetic
material, the pipe then becomes a shield, and prevents the energy from
entering the fluid path. If the fluid pipe is magnetic, it is necessary to insert a
section of non-magnetic pipe to provide the proper pipe material for the
unit to work as designed (Please see Reaction Chamber back page).
Teflon Coated Wire
For high temperature (hot water) applications of 176˚F and above,
request and use teflon wire.Teflon wire solenoid wrap sizes var y
according to pipe material and pipe size, please contact your dealer
for additional information.
the Patented Triangular Wave Technology Treatment Last Downstream
The Triangular Wave Deposit Control System will give many
years of service if sized and installed properly. Please read
all instructions carefully before assembling the system.
Introduction . . .
The Triangular Wave System is a technologically advanced method for the
treatment of hard water and its effect on fluid based applications.The system
is non-invasive and non-chemical by design and is suitable for all applications
requiring hard water treatment.
Operating Principals . . .
The signal from the Triangular Wave System circuitry flows to a solenoid
coil wound around the pipe treating and conditioning the fluid going through it.
The signal in the coil develops the modulated electrical field that immediately
conditions the water.The field penetrates the piping to its center, acting on the
passing water and the dissolved minerals and particles in the water.The
conditioning effects on the water are long lasting and last down stream.
Installation: Controller
The Triangular Wave System is easy to install. A 85 to 265 vac electrical outlet
is needed (unless other current source was requested prior to purchase) near
the unit installation.The most desirable place to install the unit is immediately
after the water meter, before any plumbing line tee, or before each piece of
vital processing equipment, so that the entire plumbing system is treated for
deposits. The unit may be installed outdoors at a wellhead for example, provided a separate weatherproof housing such as NEMA enclosure is used.
Because the unit is a solid state device, it may be mounted in any position
Control Unit Screw Mounting
For screw mounting on a flat wooden surface or other surface, use the 4 No.
6 steel self-tapping screws provided.Alternate screw mounting to a drilled
channel or plate can be done with No. 6, No. 8 or No.10 machine screws and
appropriate nuts or hardware.
Select a location that is near the pipe area and/ or equipment to be treated,
and a location that affords the equipment protection from environmental extremes.
The unit is provided with a line cord.The cord should remain unplugged until
the installation is complete and the case is closed.
A standard installation will not require access to the main control circuit board,
because all connections are available in the wiring terminal. The control circuit is
accessed by removing the front panel of the TWT unit. (Refer to Figure 1 following
page). The AC line fuses (3 AG 0.3 amp) are located on the main control
printed circuit board.
Completed System Installation Must Reflect:
A. Solenoid coil correctly field wrapped or factory wrapped Reaction
Chamber /Copper Pipe Signal Enhancer Installed
B. Visual placement of controller for periodic visual inspection of LEDs
All wires must be securely fastened and/or taped to connections
All associated wiring/conduit / line cords must be fastened with plastic wire
ties and out of harms way
IMPORTANT NOTES: Bypassing and/or eliminating water softeners
Water Softeners - Water softeners often leave deposits inside a water system;
therefore, if a softener is in use, you may want to allow the Deposit Control
System to remove the deposits before the softener is switched off. In that
case, leave the softener and the Deposit Control System on together for
about 1 month.
Remember, install the Triangular Wave system downstream of the water
softener, if you plan to run them together.
1. Wrap the coil with electrician’s tape or cloth tape (duct tape) to help
maintain a tight coil and protect the coil from being disturbed.
2. Guide both wires back to the Triangular Wave Unit and leave about
4 to 6 inches of extra wire . Strip enough insulation off the ends of the
wires to install into the barrier terminals.
3. Close the wiring trough.
4. Plug the line cord into a 120 vac outlet.

TWT Deposit Control Unit
The controller is supplied with a wiring kit and a strain relief connector for the solenoid coil wires. This strain relief will provide a water resistant seal for the two coil
wires. You should rotate the compression ring counter clockwise to release pressure
on the seal. Feed the two wires through the provided holes and tighten the compression ring. Connect the two wires to the coil terminals in the controller housing as
The Model TWT-5C8-402 to the TWT-5C8-410 are provided with an alarm
relay, which may be used for external alarms. The relay contacts are rated 5
amps @ 120 vac. The contacts are isolated from the control circuit and are
single pole double throw. If an external alarm is desired it may be connected
to Barrier terminals.
TWT® Solenoid Wrap & Reaction Chamber Guidelines
The guidelines provided herein are unique and proprietary to the TWT
patented microprocessor controller, solenoid wrap and reaction chamber.

• If the system is not installed as recommended by Triangular Wave
Technologies, Inc.
• If any modification and/or changes of the guidelines and/or installation
procedures are made without prior consultation with Triangular Wave
Technologies, Inc.
• Any deviations may cause damage to the system, and will not provide
the proper conditioning and treatment indented.
TWT Patented Deposit Control System:
The basic component in the TWT systems is the deposit controller. It is
comprised of a microprocessor, solenoid coil wrap and/or a reaction chamber. The microprocessor is a patented controller that functions like a small
computer to relay a continuous electrical po wer supply to the solenoid coil
and/or reaction chamber. The reaction chamber is plumbed into the main
water in-take line and/or just b e fore each piece of vital p r o c e s s i n g
equipment, and provides a factory-wrapped wire coil forming a solenoid.
The solenoid conveys the triangular wave signal at the appropriate
power level (as allowed by the model chosen) to the water passing through
the chamber. This signal constantly changes the polarity, frequency, and
amplitude of the current entering the water.
TWT Reaction Chamber:
The pipe material MUST provide a magnetic window for the TWT treatment
system to be able to introduce the magnetic energy necessary through the
pipe material and into the fluid within.The purpose of the reaction chamber
is to provide a means to introduce the magnetic field to colloids/ material
within the pipe. The solenoid coil configuration MUST match the TWT controller which will drive it.TWT Controllers which are intended to drive larger
pipes will be satisfactory to drive smaller pipes, the opposite is not true
(refer to tube & pipe application guidelines on TWT web site).
The following illustrations & guidelines for the solenoid wrapping of the
intended pipes are wound with Teflon type E#18 awg wire.This wire is
stranded copper with electrical insulation.The solenoid coil is formed by
laying the wire, one turn touching the next.The winding MUST be one continuous spiral. The winding should not cross over any turns, this would
cause the cross over turns to cancel each other and reduce the energy
transfer of the solenoid.
Solenoid Wrapping:
Step 1:
Measure and mark a 3.5" length on the pipe at the
selected locations for the solenoid coils.
The illustrated solenoid winding guidelines use a 3.5" length single layer
configuration (Teflon type E#18 awg wire).
Preferred Application
Step 2:
Tape this measured area with a thin material to allow the
wire to be installed side-by-side, it will provide electrical
insulation (a suitable tape is kapton).
Step 3:
Start the winding of the Teflon type E#18 awg stranded
wire in the measured area, starting at one side of the
work area and tape it in place. Be sure to measure the
distance needed, leaving enough wire to connect to the
solenoid connector when the coil is complete (Do Not
Twist or Cut Wire or the System WILL NOT Function ).
Step 4:
Wind the coil by slowly turning the pipe and guiding the
wire into the proper placement. As the winding proceeds, it is a good idea to glue the wire in place every
inch or so to insure that the coil is tight. ( be sure the
adhesive used does not react with the wire insulation).
Continue winding and guiding the wire into place until
the required 3.5" length is complete, secure the final
turn to be sure the coil remains tight. Then wrap the coil
with vinyl industrial tape to help maintain a tight coil and
protect the coil from loosening. At this point it is suggested that an impedance measurement test be made of the
coil to confirm that the coil is properly wound (suggested
test instrument EXTECH LCR meter number 380193 or
its equivalent).
IMPORTANT: When installing (wrapping) two solenoid
coils on one pipe, both coils must be wound in the same
clockwise or counter clockwise direction.Also it is necessary to connect the starting and returning wires of each
coil to the correct terminals as illustrated. Both coils are
connected to their own amplifier and these are synchronized.

Step 5:
When the solenoid coils on the reaction chamber winding is complete, a suitable covering should be prepared
to protect them The covering length should be (3.5" +
pipe ID X 2), and the OD covering of the pipe should be
pipe OD + 4". Cut the selected covering in half and then
reassembled using pipe clamps / adhesive over the coil .
Remember to drill a hole and pull the wire leads through
the hole and then connect to the suitable electrical connectors (for system integration with the TWT controller).
Center the selected cover over the solenoid coil.Place
wedges at each end of the solenoid coil, inside the
selected covering, to secure location. Again it is sug gested that an impedance measurement test be made
of the coil/ connector to confirm that they are properly
working (suggested test instrument EXTECH LCR meter
number 380193 or its equivalent).
Step 6:
Fill cavity with appropriate insulation.
Note: All selected covering used must be
non-magnetic, otherwise the performance of the
reaction chamber will be severely degraded.

Testing Equipment & Testing Procedures
Testing the solenoid wrap winding
1:The solenoid coils as illustrated is one continuous spiral of wire.
The continuity may be checked with a VOM meter set to measure
resistance. The solenoid will measure as a short or very low resistance,
a few tenths of an ohm.
2:The solenoid coil must be electrically isolated from the pipe. To test this,
Short both ends of the solenoid together and measure the resistance
from this point to the pipe. The measurement should indicate an open
3:The electrical insulation between the solenoid and the pipe should
betested. A test voltage of 600 VAC max may be used.
The impedance/ inductance of the completed solenoid should be
measured:10"pipe:0.9 milli henry +/– 10%

• TWT factory wrapped Reaction Chamber
The TWT Reaction Chamber is part of the patented TWT Deposit Control
Technology,the function of which is to control scale and bio-film in the plumbing infrastructure, fixtures, and water-fed appliances found in the facility being
treated. The Reaction Chamber provides a chamber through which the water
flows and is exposed to the triangular wave signal that lies at the heart of the
deposit control technology. As the fluid passes through, it is treated and then
carries that treatment downstream, to condition the rest of the plumbing system, non-chemically and reliably.
To use in conjunction with the TWT Deposit Control Systems when required,
Triangular Wave Technologies, Inc. has developed a line of factory-wrapped wire
coil Reaction Chambers to address magnetic pipe environments. Typically, wire
coil cannot be installed on any magnetic pipe, such as steel, galvanized steel,
ductile iron, or cast iron. If a coil is applied to such a pipe, the pipe becomes a
shield and prevents the wave energy from entering the fluid path. The TWT
Reaction Chambers solve this problem by providing an easily installed section of
non-magnetic pipe to provide the proper pipe material for the Deposit Control
System to work as designed. The TWT Reaction Chambers are fully sealed,
protecting their layers of factory-wrapped coil. The PVC, Stainless Steel and the
Industrial Reaction Chamber systems are designed and manufactured to meet
the highest quality specifications.
