    Mr.Kerry Robinson from Australia
    today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

    We've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

Product Description

Externally Heated Purge Desiccant Air Dryer -40--70℃ zero air consumption

Dew point: -40 °C - -70°C 

ISO, CE certificated With world-top activated Aluminum & Molecular contents.

Features of Externally Heated Purge Desiccant Air Dryer :


Externally heated Purge Desiccant Air Dryer is a new economic product developed by our company; This series product integrating advantages of heat-exists purge and heatless purge, externally heating the purge air, reduce it's consumption.


It efficiently avoid the disadvantages of short switching time and consuming most of the purge air of the desiccant air dryer, and wasting electricity of heat-exists air dryer.

This product has got rationally switch time, little purge air consumption, also being the most economical Desiccant Dryer in this line and widely used in metallurgy, electrical, electron, foodstuff, chemical industry, petroleum, medicine, light industry, cigarette, apparatus, auto industry and so on.


Adsorption Element

Externally Heated Desiccant Air Dryer is integrated the advantages of PSA(Pressure Swing Adsorption) & TSA(Temperature Swing Adsorption).Absorbing during normal temperature and dense water vapour; purging during relatively high temperature and less density of water vapour. That’s to say, absorb water of sorbet, purify during the purging period by superior purge air of thermal diffusion and high pressure difference.


The Flow Chart of Externally Heated Purge Desiccant

Heatless Purge Desiccant Air Dryer using micro holes in the desiccant itself, adsorbing the moisture in the air because of capillary, desorbing it by pressure drop and adsorbing extra-heat. Currently, the equipment is making up of two towers, controlled by the Program Controller, the two towers working alternately, one is for adsorbing, the other is for desorbing, in this way continually circulating the work.
