1.working principle The combined type of low dew point compress-ed air dryer(for short:combined dryer)is a low dew point drying equipment which is two in one of the freezing air dryer and the adsorption dryer.The freezing dryer has the advantages of no air loss and low energy consumption.And the adsor-ption dryer has the advantages of low dew point. The low dewpoing dryer developed by our company combines the advantages of the freezing air dryer and the adsorption dryer.Through reasonable pipeline connection and capacity collocation,Take advantages of the two dryers and achieve the highest cost performance. The combined dryer is mainly combined with the freeze dryer and the adsorp-tion dryer,and sonetimes it is attached with the filter.
