Fisair dehumidifier

Desiccant dehumidifiers provide a highly effective solution for removing moisture from the air in low temperature and low humidity environments. Desiccant dehumidifiers use a desiccant material that attracts and absorbs water vapor, removing moisture from the air.

Desiccant dehumidification systems are commonly used for applications below 45% RH down to 1% RH. They are well suited for applications where there is a need to independently control the temperature of the space and the moisture level or humidity of the space.

DRI is a global provider of products and systems for energy recovery, Indoor Air Quality, fresh air treatment, evaporative cooling, green buildings, dehumidification, and pollution control.

  • DRI Desiccant Cooling Systems

    DRI desiccant cooling systems are open-cycle systems that use water as a refrigerant in direct contact with air. The cooling cycle combines evaporative cooling, air-to-air rotary heat exchangers, and desiccant dehumidification. Low-grade waste heat or solar heat from flat-plate solar thermal collectors are normally applied as a heating system for regeneration of the desiccant rotors.
