A compressed air dryer is a device for separating moisture from industrial process air. In a typical system, the compressor attracts and compresses moist air, which increases the air temperature and then cools the moisture condensed from the device.

Refrigerated air dryers are one of the most commonly used types in industrial applications due to their ease of maintenance and relative cost-effectiveness. You can also get information about refrigerated air dryers through the web.

They are suitable for air-drying without special requirements as a minimum dew point. The principle of operation of a refrigerated air dryer is based on dehumidification of the air through rapid cooling, condensation, and drying of moisture. The operation is similar to a household refrigerator or household air conditioner.

The refrigerated air dryer removes moisture in the following phases:

  • Warm, humid air enters the dryer and quickly cools it to about 3 ° C in the refrigeration unit. 
  • At this temperature, water vapor in the air condenses into clean water, which is collected in the water trap and directed to the exhaust pipe. The warm gaseous refrigerant is cooled and regenerated in the condenser.
  • The dry air in the room is warmed to room temperature and channeled through the outlet.

Also, the refrigerated air dryer is available in two versions – cycling and non-cycling.

  • A bicycle dryer is a machine with a 100% duty cycle that can maintain the dew point at a constant temperature.
  • The non-cycling dryer will be switched off and back on periodically to maintain the required temperatureBoth options are useful in a variety of applications, although bicycle types tend to increase maintenance costs.

The dehumidifier system consists of two towers, one for dehumidification and the other for dehumidifier regeneration. The dryer tower contains a porous dryer that blocks water molecules as compressed air flows through them from the inlet
