What is a Refrigerated Air Dryer?

Refrigerated air dryers use the same cooling principal as typical air conditioning units in homes across the world. Using the refrigeration system and passing compressed air through a heat exchanger, the air is cooled to approximately 3°C/40 °F. As the air cools, water droplets begin to form in the air due to condensation much like the water droplets that form on the outside of a cold drink. The moisture laden air then undergoes a mechanical separation process where the liquid or “condensate” is separated from the air stream. The air is then rewarmed using the incoming air which lowers the relative humidity of the air and traps any remaining moisture in a vapor form.

Moisture Removal

Water in a compressed air systems can wreak havoc on a production process increasing maintenance costs and downtime as well as quality problems.

Corrosion Prevention

Removal of moisture from a compressed air system prevents rust from forming in pipes which can cause damage to tools, equipment and products.

Environmental Compliance

All Pneumatech refrigerated air dryers use environmentally friendly non ozone depleting refrigerants.
