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 humidifi ers pitch towards Ultra-sorb MP steam dispersion panel.
