Working principle：dryer
Use the refrigerant to exchange heat with the compressed air to lower the temperature of the compressed air to a dew point temperature in the range of 2 to 10°C.According to the cooling method of the condenser, the cold dryer is divided into two types: air-cooled type and water-cooled type. It consists of four parts: refrigeration compressor, condenser, evaporator and expansion valve.

When the compressor compresses the air to a certain pressure, it is delivered to the air storage tank.When the stored compressed air needs to be used, the air flows out from the air storage tank, and is transported to the required equipment or system through the discharge valve and pipeline. At the same time, when the compressed air in the air storage tank exceeds the set safety pressure, the safety valve will automatically open to release excess compressed air to avoid the danger of overload or explosion of the air storage tank.

It can filter oil mist and hydrocarbons as small as 0.01um, and the lowest residual oil content is only 0.003ppm.
Widely used in food, medicine, electronics, chemical industry, industrial waste water and other industries.

C-Class Main Line Filter：Used after the air compressor or before the refrigerated dryer, it can filter out solid particles above 3um and a large amount of liquid, and achieve the lowest residual oil content of only 5ppm.



T-Class Filter：Also known as air line filter.Used before the A-grade filters, it can filter out liquid and solid particles as small as 1um, and achieve the lowest residual oil content of only 0.5ppm.



A-Class Filter:Also known as ultra-high efficiency oil removal filter.Used after the refrigerated dryer, it can filter out liquid and solid particles as small as 0.01um, and the lowest residual oil content is only 0.001ppm.
