Description

Compressed air enters heat exchanger (1) 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 (2) 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 (3) where the condensate is separated
from the air.

The separator is integrated in the heat exchanger/evaporator.

The condensate collects in the Electronic Water Drain (EWD) and is automatically drained. The cold, dried
air flows through heat exchanger (1), where it is warmed up by the incoming air to approx. 5 ˚C (9 ˚F) below
the temperature of the incoming air.
