About this file

This is a product specification and submittal document for the DriSteem Ultra-Sorb Model MP steam dispersion panel, a humidification device used in HVAC applications.

The Ultra-Sorb Model MP is a customizable steam dispersion panel available in sizes ranging from 12" to 144" in both width and height (in 1" increments), with unit widths from 15" to 147" and heights from 19.375" to 151.375". The panel features Type 304 stainless steel construction and can be configured with either 1.5" or 2.0" diameter dispersion tubes. For evaporative steam applications, the unit delivers 700 lbs/hr capacity, while pressurized steam (2-50 psi) achieves 2,720 lbs/hr capacity. Individual tube capacities range from 40-43 lbs/hr for 1.5" tubes and 77-80 lbs/hr for 2.0" tubes, with insulated options available for improved efficiency. The humidifier accepts multiple steam inlet configurations including 1" or 2" NPT couplings for pressurized steam, 1.5" or 2" NPT couplings for evaporative steam, and 3" or 4" flange connections, with metric BSPT and hose connection options also available. The unit includes a ¾" NPT drain port and mounting flanges designed for vertical installation with horizontal airflow. Panels exceeding 98" in height are shipped unassembled and include Type 304 stainless steel components, connection hardware, tube grommets, and for boiler steam applications, float and thermostatic traps, inlet strainers, and control valves. Installation requires 100% airflow passage through the unit with sealed openings, minimum water seals (10" for pressurized, 5" for non-pressurized applications), and proper condensate drainage with air gap provisions.

Ultra-sorb Model MP mounting - pressurized steam application

Notes:

1. Locate drain 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.

2. Dashed lines indicate provided by installer.

3. Steam supply line to unit and piping are not included.

4. Mount the Ultra-sorb Model MP vertically (for horizontal airflow only).

5. For pressurized steam applications provide a 10" (255 mm) minimum water seal.

6. Locate drain 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.

7. When mounting an Ultra-sorb in a duct, headers and flanges are mounted outside the duct.

8. 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 water seals, and condensate piping connections.

9. �Due to the pressure drop across the valve, the steam pressure at the header traps is minimal. Condensate must be drained.

10. Dispersion tubes are available at : 3" (76 mm), 4" (102 mm; for 2" diameter only), 6" (152 mm), 9" (228 mm), 12" (305 mm) centers.

11. �Ultra-sorb humidifiers will be assembled, crated, and shipped intact in all sizes up to 98" (2490 mm) tall. Ultra-sorb can be shipped unassembled, by request, requiring field assembly.

12. Sizes are 12" to 144" (305 mm to 3658 mm) x 12" to 144" (305 mm to 3658 mm) in 1" (25 mm) increments.

Each Ultra-sorb humidifier is furnished with:

1. Type 304 stainless steel header/separator and dispersion tubes when shipped unassembled.

2. Hardware for connection of dispersion tubes to header when shipped unassembled.

3. Tube grommets for connection when shipped unassembled.

Each Ultra-sorb humidifier used with boiler steam is also furnished with:

1. One 3/4" NPT float and thermostatic trap (≤15 psi steam source) or an inverted bucket trap for steam main drip leg use (>15 psi).

2. Inlet "Y" strainer.

3. Normally closed steam valve with stainless steel parabolic plug and seat.

Install strainer within 3' (1 m) of Ultra-sorb

Notes:

1. Locate drain 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.

2. When mounting an Ultra-sorb in a duct, headers and flanges are mounted outside the duct.

3. Mount the Ultra-sorb Model MP vertically (for horizontal airflow only).

4. For non-pressurized steam, provide a 5" (127 mm) minimum water seal with a 2" (51 mm) minimum drop from the header connection.

5. 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 water seals and condensate piping connections.

6. Condensate must be drained.

7. Dispersion tubes are available at: 3" (76 mm), 4" (102 mm; for 2" diameter only), 6" (152 mm), 9" (228 mm), 12" (305 mm) centers.

8. �Ultra-sorb humidifiers will be assembled, crated, and shipped intact in all sizes up to 98" (2490 mm) wide. Ultra-sorb can be shipped unassembled, by request, requiring field assembly.

9. Sizes are 12" to 144" (305 mm to 3658 mm) x 12" to 144" (305 mm to 3658 mm) in 1" (25 mm) increments.

Each Ultra-sorb humidifier is furnished with:

1.Type 304 stainless steel header/separator and dispersion tubes when shipped unassembled.
2.Hardware for connection of dispersion tubes to header when shipped unassembled.
3.Tube grommets for connection when shipped unassembled.

*For electrode type humidifiers pitch towards Ultra-sorb MP steam dispersion panel.
