  • Low energy consumption
  • High reliability
  • Safe Design
  • Easy and fast installation
  • Minimized operating sound levels
  • Environmental care

Low energy consumption

  • Compliant with EU Eco-design Minimum Efficiency Performance Standards (MEPS) in cooling
  • SEER 12/7° up to 7.3 and SPER 12/7° up to 9.3
  • Twin-rotor screw compressor equipped with a high-efficiency motor and a variable capacity valve that permits exact matching of the cooling capacity of the load
  • Flooded multi-pipe heat exchangers for increased heat exchange efficiency
  • Electronic expansion device permitting operation at a lower condensing pressure and improved utilization of the evaporator heat exchange surface
  • Economizer system with electronic expansion device for increased cooling capacity

Low operating sound levels

  • Silencers on the compressors discharge line
  • Silencers on the economizer return line
  • Acoustic insulation on the components that are most subjected to radiated noise
  • Option 257 further reduces the global unit sound level

Easy and fast installation

  • Compact design
  • Simplified electrical connections
  • Simplified hydraulic connections
  • Fast commissioning

Environmental care

  • PUREtec™ R-1234ze long-term refrigerant solution
  • Leak-tight refrigerant circuit

High reliability and easy servicing

  • Increased global performance
  • Major components are selected and tested with R-1234ze refrigerant to minimize failures possibility, as well as many design choices have been taken in this perspective
  • Industrial-type screw compressors with oversized bearings and motor cooled by suction gas
  • Two independent refrigerant circuits
  • Auto-adaptive control
  • Exceptional endurance tests

Safe Design

  • Specific polyol ester oil qualified by Carrier for using with HFO-1234ze to guarantee and maintain reliable bearing lubrication
  • Specific compressor gaskets compatible with HFO-1234ze, tested and validated by Carrier
  • New relief valves designed for operation with HFO-1234ze
  • Specific electrical box with increased tightness and integrated blower that maintains positive air pressure to avoid any risk of ignition
  • New control algorithms
  • Specific documentation that contains all the installation, operation, maintenance and safety instructions

06T twin-rotor screw compressor

  • Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
  • Optimal adjustment of the compressor cooling capacity
  • If a fault occurs, the compressor does not switch off, but continues operation with a reduced capacity (unloaded mode)
  • The silencer in the discharge line considerably reduces discharge gas pulsations for much quieter operation
  • Condenser includes an oil separator that minimizes the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function

SmartVu™ control

  • Intuitive and user-friendly, coloured, 4.3" interface
  • 10 languages available
  • Easy access to the controller box
  • Password protection
  • Night-mode
  • Energy management

Remote management (standard)

  • Units with SmartVu™ control can be easily accessed from the internet, using a PC with an Ethernet connection. This makes remote control quick and easy and offers significant advantages for service operations
  • Communicates with other building management systems via optional communication gateways
  • The following commands/visualizations are possible from remote connection: 
    • Condenser pumps control: a digital input allows verification of condenser water flow (the flow switch must be supplied by the installer)
    • Start/Stop of the machine
    • Dual set-point management through a dedicated contact is possible to activate a second set-point (example: unoccupied mode)
    • Demand limit setting: to limit the maximum chiller capacity to a predefined value 
    • Operation visualization: Indication if the unit is operating or if it is in stand-by (no cooling load)
    • Alarm visualization
