Feature

Refrigerated dryers, the most commonly used dryers in industry, consist of an air-air heat exchanger and an air-refrigerant heat exchanger, which removes moisture from the compressor air through water inside the condenser, which is essential to protect the compressed air system and each unit supplied with compressed air from the harmful effects of moisture.

The most important criterion is to keep the relative humidity of compressed air below 50%.

Air-cooled and water-cooled refrigerated dryers are available. Basically, the dryer cools the warm and wet air from the compressor, and when the temperature of the compressed air is lowered, the water condenses and is expelled from the compressed air with the help of an efficient water separator. After that, the compressed air is reheated to near room temperature so that condensation does not form on the outside of the piping system. This heat exchange between the incoming and outgoing compressed air also reduces the temperature of the incoming compressed air, thus reducing the cooling capacity required for the refrigerant circuit.
