Chiltrix CXDHC-SA Psychrologix™ DHC Controller (CXDHC-SA, Unico)

Chiltrix CXDHC-SA Psychrologix™ DHC Controller


  • The Psychrologix™ chiller controller is ideal for homes, small business, or server-room cooling applications where tight humidity control and increased efficiency is required.
  • The controller manages humidity, efficiency optimization, alarms, the automatic switchover from cooling to heating, summer and winter vacation modes, and more.
  • Controls up to three chillers either in lead-lag or combined as a single larger chiller.


  • Chiltrix small air-cooled chillers with Psychrologix™ control use a unique psychrometric controls approach coupled with variable speed compressors, variable speed pumps, variable speed fans, etc.
  • The Chiltrix chillers match their capacity to the load so precisely that often buffer tanks are not needed. Not only is capacity matched in real time, but the parameters are continuously adjusted in response to conditions.
  • For example, when more dehumidification is needed, the Psychrologix™ DHC controller lowers the indoor unit coil temperature to remove more humidity.
  • When humidity is under control, the system raises the coil temperature to a more energy efficient temperature that still provides the needed cooling, but does not remove as much humidity, or may at times remove no humidity at all if humidity is already low enough.
  • Humidity removal (dehumidification, or latent heat removal) is very energy intensive and consumes a large part of the total energy used by an air conditioner.
  • When needed, dehumidification is a good thing and the Chiltrix chillers do an outstanding job of humidity removal.
  • Chiltrix chillers with psychrometric controls can also automatically perform hyper-dehumidification by increasing humidity removal to levels that surpass those of a normal chiller or air conditioner, if needed, to deal with extra high humidity.
  • Humidity does not pass through walls like heat, it requires an air flow from a more humid area, like for example, a door opening to the outside on a humid day, or an internal source such as a steamy hot shower or people exercising, etc.
  • Once indoor humidity is under control and within the user-defined range, humidity should remain low for extended periods without additional dehumidification unless additional humidity is introduced into the space.
  • During periods when humidity is in range, the Psychrologix™ DHC controller will automatically adjust the chiller parameters to provide thermostat cooling, but not provide dehumidification.
  • Turning off dehumidification saves a very large amount of energy when conditions allow.

The Unico System uses less than one-third of the space in the built environment than a traditional system. It can deliver up to 9 tons of air conditioning in the same space as a 3-ton traditional unit.
