TraneCube™ CGB chiller

15-50 kW

Main features

  • Tandem scroll compressors
  • Electronic expansion valve
  • Axial fans with 2 steps fan speed for condensing control.
  • Micro-channel condenser coils
  • Brazed plate heat exchanger with pressure differential switch and antifreeze protection electric heater
  • Microprocessor-based controller to manage unit on/off mode, operating mode setting, parameters setting, and error code display
  • Electrical panel with main disconnect switch
  • Casing and panels in galvanised and painted steel

Customer benefits

  • Compliant with European Directive ErP 2009/125/EC
  • 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.


  • Low ambient temperature kit, in cooling mode down to -10°C
  • 3-way valve for domestic hot water (power supply and control included)
  • Compressors sound jackets (low noise version)
  • Soft-starter
  • Control panel electric heater with thermostat
  • Phase failure protection relay
  • E-coated condensing coils
  • Full list of options available in product documentation


  • Serial card with BACnetTM Protocol MS/TP or TCP/IP
  • Gateway Modbus
  • Remote control panel
  • Serial card RS485
  • Flow switch
  • Automatic water filling
  • Water strainer
  • Water gauges/gas gauges
  • Rubber anti vibration mounts
  • Automatic circuit breakers
  • Power supply without neutral 400V/3Ph/50Hz


  • 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 iPRO.
