Heatless Regenerative Desiccant Dryers are suitable for sensitive, low pressure dew point applications such as -3°C, -20°C, -40°C,-70°C, etc. Although desiccant dryers offer a higher degree of water removal and are more impervious to environemtal conditions than refrigerated air dryers, they use compressed air to regenerate themselves. They are therefore very expensive to operate as the dryer will use approximately 15% of the air supply and blast it into the atmosphere - it is very expensive for compressors to produce compressed air in electrical power alone. Please note that most dryers are able to be retrofitted with a dew point controller which can significantly reduce the amount of air the dryer wastes. Heatless dryers are also sometimes called: PSA Dryers, Twin Tower Dryers, Adsorbtion Dryers, Chemical Dryers or Swing Dryers. Artic Maintenance supply a full range of dryers spanning across all flow ranges. For more information, pricing or availability click contact us
