The compressor unit draws in atmospheric air
and compresses it without oil. It then transports
the oil-free compressed air to the membrane dry-
ing unit. The cooler and the membrane dryer
extract moisture from the compressed air. The
oil-free, hygienic and dry air is stored in the pres-
sure tank ready for use in connected devices.
All of the measurement data for the unit comes
together in the control (e.g. pressure in the pres-
sure tank, temperature of the motor windings),
where it is then evaluated. Likewise, various set-
tings (e.g. switch-on/cut-off pressure) can be
adjusted, or the unit can be connected via the
network to monitoring software.
5.2 Start-up behaviour
On compressors with an electronic controller, the
compressor units are switched on with a time
delay. The time delay depends on the operating
mode selected on the controller.
Operating mode:
– Eco: 180 s
– Balanced: 60 s
– Boost: 10 s
Alternating control:
The compressor unit with the shortest operating
time since the compressor was connected to
voltage is started. This distributes the operating
time more or less uniformly between the com-
pressor units. If the compressor is disconnected
from the voltage and is then reconnected to the
power supply, compressor unit 1 will start first
again.
