Machine room ventilation<br />
The following calculation example illustrates<br />
the costs incurred due to inadequate<br />
room ventilation.<br />
Calculation example: Losses due to inadequate room ventilation<br />
Initial situation:<br />
– 4 packages with a motor rating<br />
of 37 kW each<br />
– 6,900 operating hours per year<br />
– 40 ct/kWh electricity costs<br />
– Application with a differential<br />
pressure of 500 mbar at an ambient<br />
pressure of 1,000 mbar (1 bar)<br />
In the application example, excessive<br />
temperatures, underpressure in the<br />
room and dirty suction filters result in<br />
annual costs of around € 40,848 - an<br />
enormous sum.<br />
These costs are absolutely avoidable.<br />
Even simple measures help to eliminate<br />
these unnecessary losses and at<br />
the same time solve the noise problems<br />
that can occur during process<br />
and compressed air generation.<br />
tion room can be eliminated with little<br />
effort and a manageable financial<br />
investment. Compared to the annual<br />
savings, the costs for the one-off investment<br />
in a machine room ventilation<br />
system are negligible.<br />
Minimum costs, maximum<br />
