The Basic Things About Refrigerated Air Dryers

Written by


Compressed air contains natural moisture which can affect applications requiring moisture-free air. Dryers are a common solution for removing moisture. One of the most popular options is the cold air dryer because of its ability to reach an acceptable dew point in general industrial air use.

Refrigeration dryers make up the majority of compressed air dryer applications. You can also buy refrigerated air dryers via

Quality and efficiency are important in compressed air preparation, as the use of refrigeration dryers means that dry air can be continuously available without problems. 

The cooling system cools the incoming compressed air so that water can condense and flow out. There are two types of air dryers, bicycle units, and non-bike units.

Advantages of refrigeration dryer:

Low maintenance and operating costs

Removes particles, water droplets and oil vapor from compressed air systems

High reliability and extend the life of your compressor

How do refrigeration dryers work?

Refrigeration dryers work on the same principle as household refrigerators or household air conditioning systems. Compressed air is cooled in an air-cooled heat exchanger to about 35°C, the temperature at which water vapor condenses and flows. 

The air-to-air heat exchanger works both for pre-cooling the intake air and for reheating the exhaust air as it leaves the dryer. The compressed air coming out of the dryer has a dew point at a pressure of 35 to 50°F.

Most compressed air systems do not operate in static flow and temperature conditions.
