A refrigerated air dryer means that the compressed air is cooled, which allows large amounts of water to condense and separate. After cooling and condensation, the compressed air is heated to about room temperature so that no condensation water forms outside the piping system.
This heat exchange between the incoming and outgoing compressed air also reduces the temperature of the incoming compressed air and, thus, the required cooling capacity of the cooling circuit. You can also get more information about the best refrigerated air dryers through the web.

Compressed air is cooled by a closed cooling system. Intelligent control of refrigerant compressors using an intelligent control algorithm can significantly reduce the energy consumption of modern refrigerant dryers.
Refrigerated air dryers are used for dew points between + 2 ° C to + 10 ° C and have a lower limit that is the freezing point of condensing water. They are available as stand-alone machines or as internal drying modules in compressors.
The latter has the advantage of a small footprint and offers optimized performance for the specific performance of air compressors.
Modern refrigerated air dryers use low global warming refrigerants (GWP), which means that refrigerant gas accidentally released into the atmosphere contributes less to global warming. Future refrigerants will have a lower GWP, as determined by environmental law.
