2 General description
2.1 Introduction
Description
The air dryers remove moisture from compressed air by cooling the air to near freezing point. This causes
water to condense. The condensate is automatically drained. The air is warmed up before leaving the dryer
(approx. 5 ˚C (9 ˚F) below the incoming air temperature).
The electronic regulator (1) keeps the pressure dew-point stable at no load by opening or closing the
solenoid valve of the hot-gas by-pass.
On air-cooled dryers, the condenser has a cooling fan controlled by a pressure sensor.
Water-cooled dryers have a water regulating valve in the water outlet of the condenser.
The descriptions mentioned in this book are valid for both air-cooled and water-cooled dryers.
