The purpose of a dehumidifier is to suppress the dew point of your compressed air by removing water from it. Compressed air may contain moisture that, under suitable conditions, can reach dew point temperatures and condense into a hazardous liquid.
Drying in a refrigerator means the compressed air is cooled, which allows large amounts of water to condense and separate. You can also purchase the best refrigerated air dryers through https://compressedair.net.au/refrigerated-air-dryers/.

After cooling and condensing, the compressed air is warmed back to room temperature so that no condensed water builds up outside the piping system.
This heat exchange between the intake and exhaust compressed air also reduces the temperature of the intake compressed air and thereby reduces the required cooling capacity of the refrigeration circuit. The compressed air is cooled by a closed cooling system.
Intelligent control of compressed air dryers with refrigerants through intelligent control algorithms can significantly reduce the energy consumption of modern refrigeration dryers.
Coolant dryers are used for dew points between +2°C and +10°C and have a lower limit, the freezing point of condensed water. They are available as stand-alone machines or as drying units integrated into the compressor.
The latter has the advantage of taking up less space and offering optimized performance for the particular performance of the air compressor.
Modern refrigeration dryers use refrigerants with low global warming potential (GWP), which means that refrigerants released accidentally into the atmosphere contribute less to global warming.
Future refrigerants will have lower GWP values, as required by environmental laws.
