Cooling or cold drying means that the compressed air is cooled, which allows large amounts of water to condense and separate. After cooling and condensing, the compressed air is warmed to about room temperature so that no condensation forms 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 and thus the required cooling capacity of the refrigeration circuit. You can also look for the best-refrigerated air dryers by clicking this website.

Intelligent control of compressed air dryers with refrigerants using intelligent control algorithms can significantly reduce the energy consumption of modern refrigeration dryers. Coolant dryers are used for dew points between +2°C to +10°C and have a lower limit, the freezing point of condensed water.

There are several important points to consider when purchasing a refrigerated compressed air dryer.

Maximum pressure: The maximum pressure of the dryer must be equal to or higher than that of your compressor.

Maximum flow: The maximum airflow that can flow through your dryer must be higher than your compressor can deliver. If you choose an air dryer that is too small, it will cause a large pressure drop in your dryer (because air is hard to pass).

Inlet temperature: The air dryer has a maximum intake temperature. If this temperature is exceeded, one part of the dryer may be damaged or the dryer may not have sufficient capacity to reach the desired dew point.
