5.2 Installation and Method of Operation
When the hygrostat or controller signals a demand for humidifi-
cation, the inlet solenoid valve (14) opens. The solenoid valve is
designed for pressures from 100 x 10
3
to 100 x 10
4
Pascals (1 to
10 bar).
Water is fed into the cylinder.
The water level in the cylinder must be maintained within a spec-
ified range. If the water level is too high, the ellbow acts as a
safety overflow for water drainage. If the water level is too low, it
could cause the heater element (8) to overheat. Therefore,
power supply to the heater element is shut off when water levels
are too low.
The cylinder water level is controlled by a level control (27/43).
The level control consists of a stainless steel cylinder with two
float switches and three reed contacts. The float switches indi-
cate the water level in the steam cylinder: "Dry Run", "Humidifi-
cation" and "Max. Level". The control capsule has to be
pressure-equalized.
At the standard setting, the inlet solenoid valve (14) opens when
the water level remains below “humidification” level. The water
level then rises again to “humidification” level.
The steam cylinder consists of a top (16) and lower (9) part
joined with a cylinder flange. The seal between the cylinder and
cylinder base (11), as well as between the top and lower part of
the cylinder, is maintained using an o-ring.
The heater elements are equipped with a mechanical high tem-
perature safety. This mechanism provides a redundant safety
system in the event of excessively low water levels (“Dry Run”).
Steam is fed into air-conditioning ducts through special steam
hoses and steam manifolds. Under normal conditions, this
steam has virtually no heating effect on the air to be humidified.
Accumulated condensate can be returned to the steam cylinder
via a condensate hose.
Direct room humidification (without ducts) is performed using fan
units (with blower and nozzle). The steam generator is con-
nected to the fan unit with steam and condensate hoses.
