A significant amount of heat is released during the compression of air. Most of this heat is dissipated by the screw compressor via the cooling air. A portion of the thermal energy remains in the temperature of the compressed air. Consequently, compressed air from a compressor is generally warm and moist. If this air cools down in the air receiver, the piping, or—worse still—the pneumatic equipment, condensate forms. The moisture condenses due to cooling. This moisture can be carried along in the compressed air in the form of droplets. Moisture is undesirable in many compressed air applications. Virtually all pneumatic tools are sensitive to moisture. In 90% of cases, residual moisture in pneumatic tools is the cause of malfunctions. However, residual moisture in compressed air can also cause issues in many daily applications, such as blow-off, sanding, spray painting, and the use of pneumatic cylinders. There are various methods for drying compressed air to different degrees. Condensation in the air receiver and piping network. Using a cyclone separator, where droplets are removed by centrifugal force. By installing a refrigerant air dryer. This device uses a refrigerant to lower the temperature of the compressed air to approximately +3°C, causing the moisture to condense. The operation of this type of dryer is similar to that of a refrigerator. Subsequently, the dried compressed air is reheated by the incoming air and is ready for use. By installing a membrane dryer or an adsorption dryer. These types of dryers are capable of cooling the compressed air to a pressure dew point of -20 to -70°C.
