This series of desiccant dryer incorporates the working principles of pressure swing adsorption and temperature swing adsorption. Desiccant absorbs water moisture in drying column and being regenerated with high quality dried and heated purge air in regeneration column by air thermal diffusion and high pressure difference mechanisms. heatless  regeneration  compressed  air  dryer  is  based  on  the principle of PSA, use porous desiccant to adsorb water molecules for compressed air.dryingPurge air: ≤ 12~15% Working pressure: 0.6~1.0Mpa Inlet oil content: ≤ 0.01ppm Outlet air pressure dew point: -20 ~ -40C Desiccant: Activated aluminum or Molecular siere Working periods: 4 ~ 20minutes Inlet temperature: 0~45C Hot Tags: heatless purge desiccant compressor air dryer, China, manufacturers, suppliers, factory, exporters, seller, buy, air separating machine, PSA nitrogen generate machine seller, Oil Mist Filter seller, fine filter seller, nitrogen boosters, Nitrogen Purify Set seller• Model NO.: 3.8Nm3/min-160Nm3/min • Operational Method: Continuous • Heating Mode: Convective • Trademark: Sihope • Origin: Hangzhou, China • Structure: Air Flow Drier • Operation Pressure: Atmospheric Dryer • Movement Way: Combined • Specification: Germany Standard • HS Code: 8419399090 Product Description 3.8Nm3/min-160Nm3/min Heatless Purge Desiccant Compressor Air Dryer
