Desiccant Dryers vs. Refrigerated Dryers

Desiccant Dryers vs. Refrigerated DryersWhen it comes to compressed air, one of the main problems involved is the inclusion of unwanted materials such as dirt and water, which risk condensation. A way to combat condensation is the use of industrial air dryers, which help deal with condensate. Condensation can result in equipment damage, tainting the air supply, freezing and corrosion. There are two main types of industrial air dryers, desiccant and refrigerated. Here are some facts about these two types of industrial air dryers:

  • Desiccant dryers push air through a system of highly absorbent desiccants, which sucks up any moisture and removes it
  • Heated purge desiccant dryers use an external blower and heater while heatless purge systems use compressed air to remove excess moisture, cycling through wet and dry sets
  • Refrigerated dryers work to cool the air supply to about 38 degrees, to which water vapor condenses into a liquid and is expelled from the system
  • Cycling refrigerated dryers turn on in response to detected loads while non-cycling refrigerated drying systems use a dual-stage heat exchanging system that prevents freezing by keeping a constant temperature through a hot gas bypass valve

Both desiccant and refrigerated dryers of all varieties can serve to rid your system of condensate. It is just a matter of which one benefits your facility and system best. For more information, consult with a professional that can help device the best system for your needs.
