Waterloop evaporating units

Condensation by a water circuit

Commercial refrigeration system.


Waterloop evaporator units with compressor are compact units for installation inside small cold rooms, designed with natural refrigerant R-290 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.

They have a minimum R290 refrigerant charge lower than the practical limit of the refrigerated volume.

Electrical board (optional)

Electrical power and control board for outside installation.

  • MCB protection of compressor and manoeuvre.
  • Electronic control with temperature control and recording of maximum and minimum temperatures.
  • Jet Cool function.
  • Energy saving function.
  • Optional air condenser management with waterloop temperature control and frost protection. 
  • 230V 50Hz or 400V 3N 50Hz power supply. Available in 60 Hz. Others voltages by request.
  • R-290 refrigerant charge low than 0.25 kg.
  • Bodywork in aluminium sheet and structure in galvanised steel lacquered in polyester paint.
  • Alternative hermetic or scroll compressor integrated in thermally insulated compartment, with crankcase heater.
  • Refrigeration circuit in annealed copper tube, with high pressure switch, filter drier and load valve.
  • Evaporation coil in copper pipes and aluminium fins, thermostatic expansion valve and hot gas defrost.
  • Axial motor fans.
  • Stainless steel brazed plates heat exchanger.
  • Threaded hydraulic connections.
  • Control panel in white lacquered sheet metal cabinet, with MCB protection and multifunction electronic control (optional).
  • Water solenoid valve for multi-equipment waterloop installation (without assembly).



  • Electrical board for one unit.
  • Electrical board for two units in the same cold room.
  • Without water solenoid valve for multi-equipment waterloop installation.
