A Supply and exhaust air openings in the outside walls
(free-standing installation)
B Supported by exhaust air fan
C Exhaust air duct into the open
D Exhaust air duct with recirculation flap
Hot exhaust air is mixed with the cold ambient air, as required. Thus pre-
venting the plant from freezing up at temperatures below freezing.
E Using the hot exhaust air for heating
In the winter, the hot exhaust air is used for heating rooms.
In summer it is directed into the open.
Condensate disposal
The air taken in contains water in form of vapour, which turns into condensa-
tion during compression.
WARNING!
The condensate contains oil. Never dispose of it in the public sewage system
without prior treatment.
Strictly observe the effluent disposal laws of your local authorities. Comply
with the Water Act!
BOGE recommends using an oil/water separator.
The BOGE oil/water separator is used to separate the oil from the conden-
sate. The cleaned water can be fed directly into the public sewage system.
The oil is collected in a separate container. Dispose of the oil according to
environmental regulations.
If the oil emulsifies due to special operating conditions, use an emulsion
cracking plant.
