Waterloop evaporating units

Condensation by a water circuit

Commercial refrigeration system.


Waterloop evaporating units with compressor are compact units for installation inside small coldrooms, designed with natural refrigerant R290 and waterloop condensed.

  • Compact unit condensed by water.
  • Minimal R290 refrigerant charge.
  • Easy and safe installation with connection to the condensation water circuit.


Installation of a closed loop water evaporator unit with an air cooler and general electrical panel:


Compact R290 system

The waterloop evaporator units are hermetically sealed compact systems with a minimum charge of R290, exempt from the application EN 378.
They have a minimum R290 refrigerant charge lower than the practical limit of the refrigerated volume.
