International standard manufacturer of Refrigerated Compressed Air Dryer. Our Refrigerated Air Dryers are the best in quality and purifies impure compressed air containing dust, oil as well as moisture.

Working Principal

Warm Compressed air enters into the air to air heat exchanger, where it is precooled by outgoing cold refrigeration air. Pre-cooling makes it possible to use a smaller “more economical” refrigeration unit. Then the pre-cooled air enters into the Freon Heat Exchanger, where it is cooled down to +3 degrees celcius. At this cool temperature, moisture condenses into liquid droplets, which are removed from the air stream by a very efficient demister and automatically drained by an Automatic Drain Valve. The cold dry compressed air passes back through the secondary side of the Air to Air Heat Exchanger, where it is re-heated by the incoming warm air. Reheating the outgoing compressed air increases temperature by heat with incoming warm air.

The dry air coming out from the air dryer is ready to use for instrumentation and process air applications.
