Introducing the new Defender™ Series 07/20/2010

Defender Membrane Gas Dryers utilize non porous, hollow fiber membrane tubes made of Flemion^™ to continuously remove water vapor from compressed air or sample gas, significantly lowering the water dew point and reducing the potential for moisture damage to analyzers and instrumentation. The drying process is accomplished by flowing wet air/gas through the inside of the hollow fiber membrane tubes where water vapor molecules will permeate through the wall of the membrane. The permeated water vapor molecules evaporate and are then swept away by purge gas flowing countercurrent over the outside of the membrane tubes. These dryers have the capability to lower the dew point of the supply gas to -30°C (-22°F); however, the effectiveness of the dryer will be directly related to the supply gas pressure and its dew point temperature, as well as the operating temperature of the dryer There are three series of Defender Membrane Dryers: SWB^™ Series, SWC^™ Series, and SWG^™ Series .
