Performance Features

  • Environmental stewardship and chlorine-free refrigerant HFC-134a
  • New twin-rotor screw compressor equipped with a high-efficiency motor
  • Variable capacity valve that permits exact matching of the cooling capacity to the load.
  • Flooded multi-pipe evaporator and condenser for increased heat exchange efficiency.
  • Electronic expansion device permitting operation at a lower condensing pressure and improved utilization of the evaporator heat exchange surface (superheat control)
  • Entering-fluid temperature continuously monitored to detect flow or load changes
  • Wye-delta starter or XL starter
  • Compatible with Carrier Comfort Network® (CCN) communication link
  • Certified in accordance with AHRI Standard 550/590

Reliability Features

  • Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
  • Dual independent refrigeration circuits (from 900 kW upwards).
  • Reduced number of moving parts, with compressor rotors directly driven by the motor, to lower the failure rate
  • Low voltage control circuits
  • Short cycle protection 

Maintenance Features

  • Hermetic twin screw compressors
  • Mechanically cleanable condenser and evaporator
  • Alarm contacts
  • Filter drier
  • Accessible service information including suction and discharge pressure and temperature using Navigator™ display module (factory-installed option or field-installed accessory)
  • Discharge and liquid line shutoff valves (factory-installed option)
  • ON/OFF control switch

Installation Features

  • With a relatively small width, only require minimum floor space in the plant room.
  • Victaulic connections on the evaporator and condenser, easy and fast installation
  • Possibility to reverse the heat exchanger water inlet and outlet at the factory
  • Fast commissioning, systematic factory operation test before shipment

Wide Application

  • Ice storage application with temperature down to -6° C to take advantage of off-peak electrical pricing and reduce operating cost
  • Suitable for LEED®-certified buildings and green projects, including underground rail systems, five-star hotels and high-end offices
