100 °C hot and heavily mineralized water is drained from the
steam humidifier.
The following minimum distances
(distances between the steam
humidifier and the following air-handling unit components, where
H represents the minimum evaporating distance calculated for the
given conditions) must be observed to ensure proper operation
of the steam humidifier and the entire AeroMaster XP air-handling
unit:
Humidistat piping, humidity sensor, temperature sensor:
5 x H
Very fine filter: 2.5 x H
Heating elements, filter: 1.5 x H
Duct branch piece, duct elbow, air outlet, fan: 1 x H
Note: If the „H“ value is not known, it is advisable to make the calcula-
tion with a minimum value of 1.0 m.

Condensate Drainage
Cooling, plate heat exchanger and steam humidification sections are
equipped with stainless condensate draining trays which terminate in
an outlet for the condensate draining kit connection. The condensate
draining kits are available as optional accessories. Dimensional ranges
from XP04 to XP10 are terminated in a G1/2” thread, and dimensional
ranges from XP13 to XP28 are terminated in a tube of ø32 mm
A separate condensate draining kit must be used for each individual
section. The siphon height depends on the total pressure of the fan,
and ensures its proper functioning. The type of condensate draining
kit must be designed in the course of the air-handling unit calculation.
The condensate draining piping must end in a free atmosphere, i.e. it
must not end directly in the closed sewerage system. Before operating
the air-handling unit or after being out of operation for a longer
period, it is necessary to fill the siphon via the plastic plug with water.
