EFFICIENT BY DESIGN
Reduce wasted energy and condensate up to 85%.
High-Efficiency Insulated Tubes significantly reduce airstream heat gain and
condensate production. (Standard on Model XV; optional on Models LV and
LH.)
Higher capacities per tube increase efficiency, reduce cost.
Insulated dispersion tubes produce less condensate and, therefore, have more
steam available for humidification, increasing the capacity of each tube.
As a result, fewer tubes may be required to meet application requirements,
further lowering condensate production and heat gain while reducing resource
consumption and cost.
No steam jackets; no unnecessary heat gain.
When there is no call for humidity, Ultra-sorb panels are at duct temperature
while conventional jacketed steam injection systems stay hot and continue to
add heat to the airstream.
LOWEST INSTALLATION COST
Factory assembly eases installation.
Panels ship preassembled and install quickly with easy mounting, steam, and
condensate connections.

Model XV: Operation and components
PRINCIPLE OF OPERATION AND COMPONENTS
1 Pressurized steam enters heat exchanger
Pressurized steam entry to the heat exchanger is controlled manually or by
an on-off electric solenoid valve that admits steam to the heat exchanger
when there is a call for humidity.
FIGURE 6-2: MODEL XV
PRINCIPLE OF OPERATION
2 Humidification steam enters insulated header
Humidification steam entry is controlled be either an electric or pneumatic
modulating valve, which admits pressurized steam directly to the header,
or by the STS humidifier control system, which modulates steam output from
the STS humidifier to meet humidification demand.
3 Humidification steam flows through High-Efficiency Insulated Dispersion
Tubes
Humidification steam flows through the insulated header, up the HighEfficiency Insulated Tubes, and into the airstream. Dispersion tube insulation
provides up to an 85% reduction in wasted energy by significantly reducing
airstream heat gain and condensate production. See page 9 for more
information.
4 Integral condensate management
Ultra-sorb Model XV accepts
humidification steam directly from
a boiler or DriSteem STS steam-tosteam humidifier, which transfers
boiler steam energy (through a heat
exchanger) to clean fill water to boil it
into humidification steam.
The heat exchanger vaporizes dispersion-generated condensate, which
creates condensate within the heat exchanger. This condensate returns to
the boiler via the condensate return main with no additional pumps, valves,
vents, or controls.

Model XV: Operation and components
PRINCIPLE OF OPERATION AND COMPONENTS (SEE FIGURE 7-1)
5 Control safety options
In the unlikely event that excessive header condensate cools the heat
exchanger while humidifying, a temperature switch (electric or pneumatic)
opens. This signals the modulating steam valve or STS humidifier control
system to stop humidification steam from entering the header and prevents
further condensate production. After the header condensate evaporates, the
switch closes, allowing humidification steam to flow when there is a call for
humidity.
An electric float switch (with electric control valve only) opens in the unlikely
event the humidification steam delivery header becomes flooded with
condensate. The switch opening stops the delivery of humidification steam.
After excess header condensate evaporates the float switch returns to its
normally-closed position, allowing humidification steam to flow when there
is a call for humidity.
Upon a drop in the call for humidity, the time delay relay keeps the heat
exchanger valve open for 30 minutes (or as field set), allowing steam to
flow through the heat exchanger and dry out the header. This prevents
microbial growth during prolonged non-humidifying periods.
The control cabinet, which includes the time delay relay, is required when
the solenoid and modulating valves are controlled by DriSteem.

HIGH-EFFICIENCY INSULATED DISPERSION TUBES
DISPERSION TUBE HEAT LOSS
High-efficiency tubes are standard on Ultra-sorb Model
XV and an avilable option for new or exisiting Ultra-sorb
Models LV and LH.
1600
The PVDF insulation on High-Efficiency Tubes provides the
following benefits:
1100
Uninsulated
tubes
1500
1400
1300
• Reduce heat gain and condensate production by up to
85% when using High-Efficency Insulated Dispersion
Tubes instead of uninsulated dispersion tubes,
regardless of load or airstream temperature.
• Save energy and water. Every pound of condensate
that does not drain from the dispersion assembly saves
the Btus (about 1,000) required to boil it into steam.
• Gain capacity. Specify fewer tubes and smaller steam
generators. With a higher percentage of generated
steam meeting the humidification load, fewer
dispersion tubes are needed and steam generators can
be downsized in many cases.
ADVANCED INSULATION MEETS STRINGENT REQUIREMENTS
PVDF is an advanced material commonly used in
chemical, semiconductor, medical, defense, and
aerospace industries and has the following characteristics:
• Approved for use in plenums. Flame spread/smoke
developed values are 0/0, exceeding UL 723 (ASTM
E84( requirement of 25/50.

• To avoid damaging the header and heat exchanger, drill or screw through the header assembly only where shown in the Ultra-sorb Model
XV Steam Dispersion Panel Installation, Operation, and Maintenance Manual (available at www.dristeem.com). Screws and drill bits must not
penetrate more than 3/4" (20 mm) into the header assembly.
• Recommended fasteners for mounting the Ultra-sorb to a metal support frame are 1/4–20 nuts and bolts or #12 self drilling and tapping screws.
• DRI-STEEM recommends fastener spacing not to exceed 6" (150 mm).
• When Ultra-sorb Model XV is installed in bypass air applications additional bracing is advised for the unsupported side(s).
• Install the panel level. If slope cannot be avoided, ensure that the slope is toward the drain end of the panel.

Choosing a location for Ultra-sorb
DETERMINE HUMIDIFIER PLACEMENT
Check available non-wetting distance, and review Figure 18-1. Dispersed
steam must be absorbed into the airflow before it comes in contact with duct
elbows, fans, vanes, filters, or any object that can cause condensation and
dripping.
PLACEMENT IN AN AIR HANDLING UNIT
• Location A is the best choice. Installing downstream from heating and cooling
coils provides laminar flow through the dispersion unit; plus, the heated air
provides an environment for best absorption.
• Location B is the second-best choice. However, in change-over periods, the
cooling coil will eliminate some moisture for humidification.
• Location C is the third-best choice. Air leaving a fan is usually very turbulent
and can cause vapor to not absorb at the expected non-wetting distance.
Allow for more distance if installing downstream from a fan.
• Location D is the poorest choice. The cooler air at this location requires an
increased non-wetting distance.

Notes:
1. For pressurized steam applications we recommend installing a 10" (255 mm) minimum water seal or a float and thermostatic (F&T) trap.
F&T traps are approximately 7" (180 mm) in height.
2. Locate air gap only in spaces with adequate temperature and air movement to absorb flash steam; otherwise, condensation may form
on nearby surfaces.
Refer to governing codes for drain pipe size and maximum discharge water temperature.
3. When mounting an Ultra-sorb in a duct, headers and flanges are mounted outside the duct.
4. 100% of the airflow must pass through the Ultra-sorb, which means that any openings surrounding it must be sealed. The blanked-off
area below the Ultra-sorb provides clearance height for F&T traps, water seals, and condensate piping connections.
5. Dashed lines indicate provided by installer.

2. Locate air gap only in spaces with adequate temperature and air movement to absorb flash steam; otherwise, condensation may form on
