First stage:
Warm compressed air entering the first section of the heat exchanger gives up some of its heat to
the chilled and dried compressed air leaving the dryer.
Second stage:
Further air cooling takes place in the second part of the heat exchanger through which refrigerant
flows. The refrigerant gives up its heat to the surroundings in the refrigerant condenser.
Third stage:
A separation system integrated in the heat exchanger removes the condensate precipitated out of
the compressed air as it is chilled. The condensate drain reliably drains the condensate from the
separator.
Fourth stage:
The dry, chilled air takes in some heat from the inflowing warm compressed air in the first part of
the heat exchanger. The relative humidity of the compressed air drops.
