Stage 3
– Pipework for HTHW / Raw steam
HTHW Supply
& Condensate
Installation
Connect the HTHW inlet(s) to an adequate HTHW supply with 3 way diverting
control valve, isolating valves, regulating valve and thermometers.
Only one (1) control valve is required irrespective of the number of HTHW
inlets.
The control valve must be fitted with a mechanism and be electrically wired so
that the valve returns to the closed position when no air flow is detected in the
AHU.
The return outlet(s) must be connected to the HTHW with an isolating valve.
Thermometers must be installed on the HTHW supply line and the return line
close to the humidifier.
Typical Raw Steam Installation
A strainer as well as an isolating valve must be installed upstream to the
control valve on the raw steam supply pipe.
Two vacuum breakers (not supplied) must be installed at the highest
practical points. Installation must be done only in the vertical upright
position.
Brass coupling must be used between the heat exchanger stainless steel
pipes and steam inlet / condensate outlet piping.
The condensate must be evacuated efficiently. Therefore, a condensate
pocket and stream trap must be installed to ensure proper condensate
elimination.
Only float and thermostatic type steam trap must be used to eliminate
condensate from the heat exchanger. This steam trap needs be able to
withstand at least twice the humidifier duty.
Do not use thermostatic or Thermodynamic traps to eliminate condensate
from the heat exchanger. Those traps can be used as small capacity traps
to eliminate condensate from raw steam line only.
After installation, field piping and Humidifier Steam piping must be checked
for leak.
All leaks MUST be sealed prior to commissioning the Humidifier.
Steam Supply Size
Size of the steam supply pipe and control valve must be calculated
considering
1.35kg of raw steam for each kg of clean steam
produced
and distributed into AHU.
