The Compressed hot regenerative air dryer is Absorbing the advantages of high temperature desorption of thermal adsorption dryer and larger adsorption capacity of non-thermal adsorption dryer at room temperature.It avoids the shortcomings of short switching time and large regeneration loss of non-thermal adsorption dryer.At the same time, it also overcomes the disadvantages of large energy consumption of heat adsorption dryer.The compressed hot regenerative compressed air dryer uses the characteristics of high temperature of the air compressor to carry out the regeneration and dehydration of the adsorbent. At the same time, the principle of pressure swing adsorption at room temperature is adopted to achieve the purpose of drying compressed air.It has the characteristics of low energy consumption (compared with the micro heat dryer), high efficiency, no environmental pollution,Compressed air quality and other characteristics.It is applicable to oil-free screw air compressor and also It is suitable for other centrifugal air compressors with exhaust temperature at 110-140 degrees.The main feature of this equipment is that the regeneration loss gas is small (compared with the micro heat dryer), which saves energy and the air dew is stable and reliable。
