Global Chiller
30HXC

Water-Cooled
Liquid Screw Chiller
R-134a Refrigerant
Source: France

286 to 1302 Nominal kW
81 to 370 Nominal Tons

The 30HXC units are freshwater- or seawater-cooled chillers, designed from the ground up to meet the needs of today and tomorrow:

  • Non-ozone depleting HFC-134a refrigerant
  • Screw compressors
  • Fits through narrow access doors without disassembly
  • Mechanically cleanable evaporators and condensers
  • Wide range of marine & offshore customizations

All units are equipped with Pro-Dialog Plus control to optimize the efficiency of the refrigerant circuit.

Performance Features

  • Chlorine-free R-134a HFC refrigerant
  • Low energy consumption during part load and full load operation
  • Twin-rotor, gear-driven, multiple screw compressors allow precise capacity matching of building load changes and significantly reduce unit power input, especially at part-load.
  • Flooded multi-pipe heat exchangers for increased heat exchange efficiency.
  • Leaving-fluid temperature directly controlled to within 0.5°F (0.3°C)
  • Entering-fluid temperature continuously monitored to detect flow or load changes
  • Compatible with multi-protocol communication links to shipboard automation
  • Electronic expansion device permits operation at a lower condensing pressure and improved utilization of the evaporator heat exchange surface.

Reliability Features

  • Two independent refrigerant circuits - the second one takes over automatically, when the first one malfunctions, maintaining partial cooling under all circumstances.
  • Low voltage control circuits
  • Short cycle protection
  • Dual chiller control
  • Temperature reset from return fluid
  • Electronic paddle-free flow switch, pre-installed on evaporator
  • Electronic refrigerant gauges
  • Heat exchangers available with class approval (DNV-GL, BV, LR)

Maintenance Features

  • Hermetic twin screw compressors
  • Mechanically cleanable condenser and evaporator
  • Alarm contacts
  • Filter drier
  • Moisture indicating sight glass
  • Pro-Dialog Plus monitors all chiller safety parameters
  • Remote management capabilities

Installation Features

  • Unit width of 980 – 1015 mm (38.6 – 40.0 in.) across the range
