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 for improved capacity modulation and energy savings.
  • 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
  • Fan external static pressure up to 300 Pa
  • Water side plate heat exchanger with differential pressure switch and antifreeze protection electric heater
  • Electronic expansion valve          
  • Microprocessor-based controller to manage unit on/off mode, operating mode setting and parameters setting
  • Casing and panels in galvanized and painted steel
  • Full compliance with EU Regulation 2016/2281 for comfort chillers

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.
  • Perfect for large variety of buildings and applications
    • Building roof curved or not large enough
    • Floor-by-floor AC system with individual metering / billing
      • Example: High class apartment buildings
    • Noise-sensitive installations
    • “Hidden” indoor installation eliminates neighborhood complaints
    • Ducted air inlet and discharge:
    • Easy installation of customized duct silencers satisfying
      • Specific noise requirements
    • Allows isolating the machine room from low outdoor air temperature
      • Examples: Theaters/Hotels/Office buildings in (old) city centers
    • Areas with heavy air pollution.  Indoor installation protects unit against corrosion.  Apply good quality coating on condenser coil


  • Compressors sound jackets
  • Soft - starter
  • Serial communication card RS 485
  • Power factor correction to cosphi = 0.91
  • Automatic circuit breakers
  • Desuperheater
  • Over/under voltage + phase failure protection relay
  • Epoxy coated condensing coils
  • Pre-painted condensing coils
  • Copper/copper condensing coils
  • Advanced iPro microprocessor controller with BACnet, Modbus, LonTalk serial card option


  • G4-EU4 condenser inlet air filters
  • Remote control panel
  • Flow switch
  • Automatic water filling
  • Water strainer
  • Water gauges
  • Gas gauges
  • Rubber or spring anti-vibration mounts
  • Microprocessor-based controller to manage unit on/off mode, operating mode setting, parameters setting, and error code display
  • Carel electronic expansion valve 
  • Setpoint arbitration is the strategy used to select final, authoritative values from multiple input sources:
    • External inputs are “hard wired“ directly to the local chiller controller with low voltage binary (On/Off or Cool/Heat Mode)
    • External setpoint with 4-20mA analog signals or double setpoint with digital input. In this case it is necessary to order the iPRO unit controller
    • BMS Inputs (Optional)  are Building Automation Systems which can talk to the chiller controls over network serial links including Modbus, Lon Talk and BACNet. The last two are available only with I-Pro.
