R290 intarWatt

R290 chillers

Chillers in compact construction and outdoor installation of glycol, water or brine and a low R290 charge.

Description

Water, glycol or brine chiller for outdoor industrial refrigeration applications. Also, the R290 intarWatt chiller is characterised by:

  • Built-in hydraulic unit (optional).
  • Low refrigerant charge R-290.
  • No need for machine room.
  • Plug & Play system.
  • Optimised compact system, with minimum maintenance.
