Description
Compressed air enters heat exchanger (101a) and is cooled by the outgoing, cold, dried air. Water in the
incoming air starts to condense. The air then flows through heat exchanger/evaporator (101b) where the
refrigerant evaporates causing the air to be further cooled to close to the evaporating temperature of the
refrigerant. More water in the air condenses. The cold air then flows through separator (102) where all the
condensate is separated from the air.
The condensate collects in the electronic water drain (401) and is automatically drained. The cold, dried air
flows through heat exchanger (101
a), where it is warmed up by the incoming air to approx. 5 ˚C (9 ˚F) below
the incoming air temperature.
Condensation in the air net cannot occur unless the air is cooled to below the pressure dew-point indicated
on the control panel.
