Compressed air circuit
Compressed air enters the heat exchanger (1) and is cooled by the outgoing, cold, dried air.
Water in air starts to condense. Then, the air flows through the heat exchanger/evaporator (2),
where the refrigerant evaporates.
This causes the air to cool further close to the evaporating temperature of the refrigerant. More
water in the air condenses.
