Ventilation device
For optimum ventilation of the heat exchanger, we rec-
ommend that you install suitable air separators at the
highest points of the system (e.g., above the air han-
dling unit), which reduce the airflow velocity by
increasing the cross section and can thus be ideally
used for deaerating glycol systems.

Hot surfaces
WARNING!
Risk of injury from hot surfaces!
Steam heat exchangers are operated with tempera-
tures of >100 °C. Contact with surfaces of the heat
exchanger causes severe skin burns.
Before performing any work on the heat exchanger,
the supply of steam must be interrupted and you
must ensure that the surface temperature has cooled
down to room temperature, e.g. using an infrared
thermometer.
DANGER!
Risk of leakage due to escaping steam
If steam is released due to leakages, the supply of
steam to the heat exchanger must be stopped imme-
diately.
The heat exchanger must be fully emptied before
repair work can be carried out. The steam is subject
to high pressure; if the steam escapes due to a
leakage, a hot steam jet can occur that can cause
severe scalds.
Connect steam heat exchangers in a counter flow
arrangement unless a parallel flow arrangement has
been specified by the manufacturer. Only a counter flow
arrangement ensures that the calculated capacity is
achieved.
If you have to attach brackets or fasteners to the
AHU panels or frame, use only those specially
approved for your AHU as otherwise there is a risk of
leakages.

exchanger connections in a counter flow arrangement.
1 Airflow direction
Stickers on the connection side of the heat
exchangers indicate the flow ( Fig. 34 /IN) and return
connections ( Fig. 34 /OUT) for a counter flow
arrangement.
In special designs of the heat exchanger, these
stickers may not show the correct type of connection.
The heat exchangers must always be connected in a
counter flow arrangement.
For steam-operated heat exchangers, the return con-
nection must be located at the bottom so that any
condensate that occurs can be properly dissipated.
For questions on the connections, please contact the
unit manufacturer.
