 General Introduction: 
Commonly, there are two kinds of compressed air dryer: refrigerated compressed air dryer and regeneration adsorption one. The refrigerated compressed air dryer is quite energy-saving without any air loss, While it is limited by the dew point temperature. The regeneration adsorption compressed air dryer can reach a quiet low dew point, but it has the shortcoming of big air loss and high energy consumption.
The SHANLI combined low dew point compressed air dryer takes the maximum advantages of the above two kinds of dryers through reasonable pipeline connection and capacity matching, which ensure its economic operation and high quality of low dew point finished air.
 Operating Principle:
Firstly, the hot and wet compressed air from the compressor is heat exchange with dried cold compressed air in the heat exchanger. Then it will be cooled down to about 2ºC by evaporator. Under this pressure dew point, the majority of vapor water in the compressed air is eliminated and discharged. After these processes, the low temperature air goes into the heat exchanger to cool the high wet compressed air, at the same time, itself temperature goes up in order to prevent the condensation of dew on the surface of pipelines. Last, low moisture compressed air dryer goes into the adsorption vessel to be further dried  in order to get the good dew point.

Product features

1. Low dew point:The combined low dew point dryer can reach very low pressure dew point, which can reach below - 40 ºC in general, and - 70 ºC at least according to different user requirements;
2. Low energy consumption: the regeneration gas consumption of combined low dew point dryer is only 3% - 5%, which greatly saves the compressed air consumption;
3. It can provide compressed air with different dew points for different air consumption points;
4. All the operation switches and display instruments of the combined low dew point compressed air dryer are concentrated on the panel of the box plate. The refrigeration type compressed air dryer and the adsorption regeneration compressed air dryer can operate independently or simultaneously with cold and suction according to the customer's needs;
5. The gas-liquid separator adopts the patented three-stage separation mode: direct collision separation + low-speed centrifugal separation + stainless steel wire mesh demisting separation. 99.9% of liquid water is separated from the cooled compressed air. The second evaporation of textile moisture can ensure the low dew point quality of finished gas.
6. High quality switching valve, stable and reliable, can ensure the integrity of the working process and prolong the working life of components.
7. The refrigeration compressor adopts Danfoss of Denmark, Fusheng of Taiwan, Panasonic of Japan, Bitzer of Germany, Copeland of Germany, maneurop of France and other companies of fully closed or semi closed refrigeration compressor, which has stable operation, low noise, high cop, reliable performance and long power saving life;
