Dehumidifiers

Aggreko offers two methods of industrial air dehumidification: refrigerative drying or desiccant drying.

Refrigerative drying works best with a strong temperature differential, which means that refrigerative dehumidifiers are most effective at high ambient temperatures and high humidity. Their effectiveness may be significantly reduced in colder climates.

Aggreko also offers desiccant dehumidifiers, which are custom-manufactured with an internal silica-gel wheel. This wheel simultaneously absorbs water vapor in one section of the wheel, while the silicate is being regenerated (dewatered) in another section. When available electrical power is limited, these dehumidifiers can be engineered to be regenerated by heating with natural gas, propane, or steam. These units have been successfully applied in numerous applications including:

  • Manufacturing and construction, for reducing the drying time of wet concrete, speeding up painting and coating operations, or minimizing corrosion,
  • Process applications, such as stabilizing or preserving food products,
  • Restoration of buildings and manufacturing facilities after flood damage.
