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. These units are characterised by:

  • 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.
