Hospitals
EFFICIENT BY DESIGN
Reduce wasted energy and condensate up to 85%.
High-Effi ciency Insulated Tubes signifi cantly reduce airstream heat gain and condensate production. (Standard on Model XV; optional on Models LV and
LH.)
Higher capacities per tube increase effi ciency, reduce cost.
Insulated dispersion tubes produce less condensate and, therefore, have more steam available for humidifi cation, 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.

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.
2 Humidifi cation steam enters insulated header
Humidifi cation steam entry is controlled be either an electric or pneumatic modulating valve, which admits pressurized steam directly to the header, or by the STS humidifi er control system, which modulates steam output from the STS humidifi er to meet humidifi cation demand.
3 Humidifi cation steam fl ows through High-Effi ciency Insulated Dispersion
Tubes
Humidifi cation steam fl ows through the insulated header, up the High-
Effi ciency Insulated Tubes, and into the airstream. Dispersion tube insulation provides up to an 85% reduction in wasted energy by signifi cantly reducing airstream heat gain and condensate production. See page 9 for more information.
4 Integral condensate management
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.
FIGURE 6-2: MODEL XV
PRINCIPLE OF OPERATION
Ultra-sorb Model XV accepts humidifi cation steam directly from a boiler or DriSteem STS steam-tosteam humidifi er, which transfers boiler steam energy (through a heat exchanger) to clean fi ll water to boil it into humidifi cation steam.

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 humidifi er control system to stop humidifi cation steam from entering the header and prevents further condensate production. After the header condensate evaporates, the switch closes, allowing humidifi cation steam to fl ow when there is a call for humidity.
An electric fl oat switch (with electric control valve only) opens in the unlikely event the humidifi cation steam delivery header becomes fl ooded with condensate. The switch opening stops the delivery of humidifi cation steam.
After excess header condensate evaporates the fl oat switch returns to its normally-closed position, allowing humidifi cation steam to fl ow 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 fi eld set), allowing steam to fl ow 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.
Heat exchanger control options
Heat exchanger options are packaged and available for ordering as shown below.
Boiler steam only (no STS Humidifi er): a. Heat exchanger solenoid valve, time delay relay, fl oat switch (if electric valve), temperature switch (if pneumatic valve) and control cabinet b.

ULTRA-SORB STEAM DISPERSION PANELS
Model XV: Operation and components
HIGH-EFFICIENCY INSULATED DISPERSION TUBES
High-effi ciency tubes are standard on Ultra-sorb Model
XV and an avilable option for new or exisiting Ultra-sorb
Models LV and LH.
The PVDF insulation on High-Effi ciency Tubes provides the following benefi ts:
• Reduce heat gain and condensate production by up to
85% when using High-Effi cency 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 humidifi cation 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.
• Rated for high-temperature operation.
Rated for 300°F
(149°C) continuous operation.
• Will not absorb water or support microbial growth due to its closed-cell construction.
• Virtually no airfl ow pressure drop.
PVDF insulation is only 1/8" (3.2mm) thick.
• Will not shift or slip on tubes.
Advanced manufacturing process ensures insulation attaches securely to tubes.
• Odor free.
Virtually no measurable outgassing.
• Resistant to UV light.
• Rugged and durable.
No particle erosion per ASTM
C1071 erosion resistance test; does not contain fi berglass.

Models LV and LH: Operation and components
HIGH-EFFICIENCY INSULATED RETROFIT OPTION
1 Steam enters steam supply header
Pressurized steam from a boiler or nonpressurized steam from a DriSteem steam generator enters the supply header/separator after passing through a modulating steam control valve.
2 Steam enters dispersion tubes
Steam through the dispersion tubes and into the airstream. Dispersion tube diagonal end cuts capture only the driest steam from the center of the header.
Calibrated thermal resin tubelets allow only the driest steam to exit into the airstream.
The dispersion tubes operate drip-free without steam jackets, so no unnecessary heat is added to the airstream when the humidifi er is idle.
High-Effi ciency Insulated Dispersion Tubes, available as a new or retrofi t option, provide up to an 85% reduction in wasted energy by signifi cantly reducing airstream heat gain and condensate production. See
Pages 9 and 15 for more information
3 Condensate fl ows to condensate return header and drain
Any condensate generated in the dispersion tubes fl ows by gravity to the condensate return header to the condensate drain.

ULTRA-SORB STEAM DISPERSION PANELS
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 airfl ow before it comes in contact with duct elbows, fans, vanes, fi lters, 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 fl ow 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 humidifi cation.
• 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 fl oat 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 fl ash 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 fl anges are mounted outside the duct.
4. 100% of the airfl ow 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.
