CHRIS LOGOCHRIS – 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℃ 
  • 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 refrigeran


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

Where to use

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