,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.
