RECOMMENDATIONS
Trapping - steam supply and pressurized condensate return
•
Low pressure, up to 15 psi (103 kPa) — fl oat and thermostatic (steam)
trap (Figure 12-1)
•
High pressure, more than 15 psi (103 kPa) — inverted bucket trap
(Figure 12-2)
•
Lifting condensate — Steam trap (up to 15 psi/103 kPa) or inverted
bucket trap (Figure 12-3)
Driest steam
To ensure driest steam, take humidifi er steam off the top of the steam main
(not the side or bottom).
Airfl ow proving switch
Use an airfl ow proving switch to prevent humidifi cation steam from entering
the header if air is not moving in the duct.
High limit humidistat
To prevent over saturation use a high limit (duct mounted) humidistat (Figure
6-1). Mount it 10' to 15' (3 to 4.5 m) downstream from the Ultra-sorb
panel, and set it at 80 to 90% RH.
HEAT EXCHANGER PRESSURIZED BOILER STEAM INLET (SEE FIGURE 11-1)
Steam pressure for steam entering the heat exchanger must be least 5 psig
(35 kPa) to vaporize condensate in the header.

Integral heat exchanger
• Ultra-sorb Model XV employs an integral
heat exchanger to pressurize and lift
condensate up to 12" per psi (300 mm
per 6.9 kPa) of steam pressure.
• Steam pressure entering the heat exchanger
must be at least 5 psig (35 kPa).
• Condensate may be piped to the condensate
return main.
