Compressor room
Ventilators
Ensure that the heated exhaust air is not taken in again.
If necessary, the heated air must be extracted by ventilators.
To ensure perfect cooling even at higher temperatures in the summer, the ven-
tilators must be designed as follows:
–
The ventilator capacity must be rated approx. 10 – 15% higher than the
sum of the cooling air quantity required for all machines operated in the
room.
–
For a free-standing installation, the cooling air requirement specified in the
table corresponds to the required ventilator capacity.
Cooling air requirement
Please refer to the following table for the cooling air requirement and size of
the supply air openings for your compressor. Ensure that flaps and weather
protection grids have the necessary free cross section. We generally recom-
mend contacting a specialist company for performing the duct construction
work and planning.
* For the cooling air requirements the basis is a 39°F temperature difference between room and outside tempera-
ture.
Table 3.1: Cooling air requirement, necessary aperture dimensions.
Condensate disposal
The air taken in contains water in form of vapour, which turns into condensa-
tion during compression.

Attention!
The condensate contains oil. Never lead it into the public sewage system
without prior treatment.
Strictly observe the effluent disposal laws of your local authorities.
Oil-water separator
The BOGE-oil-water-separator separates the oil from the condensate.
The cleaned water may 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, due to special operating conditions, the oil should emulsify, use an emul-
sion cracking plant.
