Description


  • 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
