CGCM chiller

44-315 kW

Main features

  • Hermetic scroll compressors, low vibration and low sound level
  • High efficiency plug fan for indoor installation with ducted air intake and discharge. Optional EC plug fan for increased external static pressure up to 400 Pa.
  • Waterside plate heat exchanger with differential pressure switch and antifreeze protection electric heater
  • Airside heat exchanger high efficiency finned coils with seamless copper tubes expanded into corrugated aluminum
  • Thermostatic expansion valve
  • Casing and panels in galvanized and painted steel
  • Horizontal or vertical air flow

Customer benefits

  • Compact dimensions allow for flexible installations in both new and existing buildings
  • Maintenance operations are easy thanks to the location of the components
  • Excellent acoustic comfort levels
  • Digital Defrost is a self-adaptive defrosting system able to intervene only in case of a consistent thickness formation of ice on the coils’ fins
  • Dynamic Logic Control manages the differential of the inlet water temperature on the basis of the speed of its variation. Thanks to the DLC the number of the compressor starts decreases ensuring economic and energy savings
  • Dynamic Set Point function allows changing the setpoint simultaneously to always achieve the conditions of best comfort and maximum energy savings.
