Desiccant dehumidifier

Our Desiccant dehumidifiers make effective dehumidification possible in environments and processes requiring low temperatures, such as cold storages, low-temperature logistics facilities, meat handling, processing marine products, ice rinks. A wide range of beneficial results can be achieved, including improved hygiene through the prevention of condensation on floors and equipment, the prevention of equipment aging, improved safety, and the prevention of product deterioration due to moisture.

chris - Desiccant dehumidifier using the heat pump


chris makes it possible to dehumidify in low temperature circumstances with more energy-saving operation applying a heat pump using carbon dioxide as regeneration heat source.
chris expands possibilities for using Desiccant dehumidifiers, even in refrigerated facilities lacking a heat source such as steam or waste heat.
・Dehumidification in low-temperature environments 5 to -5℃ (41 to 23℉)
・Since drying is possible even in low-temperature environments, the occurrence of mold and rust is curtailed
・Reduced energy consumption of 50% (our company’s comparison) has been achieved compared to conventional desiccant humidifiers (electricity regeneration type)
・Safe, natural CO2, which has low global warming potential (GWP), is used for the heat pump refrigerant


  • Intake air flow rate: 4,000 to 8,000m3/h (2354 to 4708CFM)
  • Refrigerant: CO2 (R744)
  • It is possible to dehumidify air colder than 0℃ (32℉)


  • C-class cold storage
  • Cargo handling rooms
  • Processing plants (cutting rooms, etc.)
  • Ice skating rinks
