4 The inlet grids and ventilation fan should be installed in such a way that any recirculation
of cooling air to the compressor inlet grid is avoided. The maximum air velocity through
the grids is 5 m/s (16.5 ft/s).
If cooling air ducts are installed, the maximum allowable pressure drop over the ducts is
30 Pa (0.12 in wc).
The air temperature at the compressor inlet grid should be between 0 °C and 46 °C (32
°F and 114.8 °F).
The required ventilation to limit the compressor room temperature can be calculated as
follows:
For SI Units:
On air-cooled compressors: Qv = 0.92 N/dT
Qv = Required ventilation capacity in m
3
/s
N = Shaft input of compressor in kW (for Pack compressors)
N = Shaft input of compressor in kW + heat dissipated by dryer in kW (for Full-Feature
compressors)
dT = Temperature increase in compressor room
For British/American Units:
On air-cooled compressors: Qv = 2618.5 N/dT
Qv = Required ventilation capacity in cfm
N = Shaft input of compressor in hp (for Pack compressors)
N = Shaft input of compressor in hp + heat dissipated by dryer in hp (for Full-Feature
compressors)
dT = Temperature increase in compressor room
5 Drain pipes to condensate collector. The drain pipes should be connected to an open
circuit.
6 Control cubicle with monitoring panel
7 Main cable entry
- A water shut-off valve and water drain valve in the energy recovery water inlet pipe and
outlet pipe can be installed by the customer. If water shut-off valves are installed, a safety
device with set pressure according to the maximum water inlet pressure has to be installed
between the energy recovery water outlet pipe and the shut-off valve.
Notes
• For more information concerning air nets, cooling systems, etc. check the compressor installation manual.
• All pipes should be connected stress free to the compressor unit.
• For dimensions and air flow directions check the dimension drawings.
