AquaForce®
30XW-G

Water-Cooled Screw Chiller, 60 Hz
With R134a Refrigerant

Cooling capacity: 880~1,887 kW

  • Absolute reliability
  • Non-ozone depleting R-134a
  • Easy and fast installation
  • Pro-Dialog controls
  • Remote management

The Aquaforce® liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building owners require optimal performances and maximum quality. The Aquaforce liquid chillers are designed to meet current and future compactness.

Performance Features

  • Non-ozone depleting chlorine-free refrigerant HFC-134a
  • AHRI certified maximum full load efficiency up to 0.573 ikW/Ton and IPLV to 0.430 ikW/Ton
  • 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
  • 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

  • Water source heat pumps 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
