Refrigerated compressed air dryer DH-12

There is moisture with 100% of relative temperature in compressed air, and as it cools in the pipe, the water will be precipitated. In compressed air system, if there have moisture, it will bring a lot of drawbacks to users: First, the operation and maintenance costs will increase, that is, the instrument, solenoid valve, cylinder and other components of the maintenance costs are increased; the efficiency of the equipment is reduced and it may cause production disruptions. Due to it needs to add condensate, separation, drain and other equipment in the system, so the entire production line of equipment investment will increase. The quality of production process will be affected by the high moisture content of the compressed air, thus will affect the quality of the products, especially in spray painting, sandblasting, pneumatic control systems, food processing, pharmaceutical and other industries. The degree of dryness of compressed air is usually expressed by dew point temperature. Dew point refers to the temperature at which water vapor begins to condense by cooling, from vapor to liquid.
