HOW THE DONALDSON DRYER WORKS
Compressed air is fed into the dryer and is precooled
in the air-to-air heat exchanger by the
outgoing cold compressed air. The precooled
air then passes through the refrigerant-to-air
heat exchanger where it is further cooled to the
required pressure dewpoint. The moisture in the
compressed air condenses out and is collected
and discharged automatically. Finally, the cold discharged air is rewarmed by the incoming compressed air. This saves energy & prevents any moisture forming beyond the dryer in the compressed air system.
