Learn About Desiccants

Green SERVPRO desiccants. At SERVPRO we use a variety of drying equipment to restore water damaged materials your Michigan property back to preloss conditions.

At SERVPRO of West Sterling Heights we use a variety of drying equipment to restore water damaged materials your Michigan property back to preloss conditions. One piece of equipment that excels at large loss drying is the desiccant dehumidifier. 

A desiccant dehumidifier has a moisture absorbing wheel inside the unit. The wheel is made of silica gel – which is the desiccant (drying) element. Air enters the unit through an opening and travels through the silica gel impregnated wheel. When the air reaches the other side of the wheel it is dry and pushed out of the unit by a high static blower. 

The process is as follows: 

  • Dehumidifiers absorb moisture from the air into desiccant materials. 
  • The air to be dried, or processed, is ducted through the rotor in one air stream. 
  • The rotor brings the moist desiccant to the reactivation air stream to heat it up. 
  • Moisture is expelled from the desiccant material as water vapor. 
  • Moist, warm air is ducted outdoors. 
  • The separate air streams move in different directions, blowing any debris away from the processed air. 
  • Dried processed air is circulated back into the area. 

Desiccant dehumidifiers range in size and configuration dramatically. They can be as small as a suitcase or as large as two semi tractor-trailers. Large desiccants are often self-contained dehumidification systems, utilizing onboard generators and running on propane or diesel fuel. When large catastrophic events occur, such as hurricanes or floods, large desiccants can provide a way of dehumidification when little or no power is available. 

If you experience water damage in your home or business, a desiccant dehumidifier might be used, depending on the extent of water damage. Here at SERVPRO we specialize in water damage restoration, the cornerstone of our business. We have extensive water damage restoration training, and our process emphasizes regular monitoring and documentation of the drying process from beginning to end.
