Performance Features
- Chlorine-free R-134a HFC refrigerant.
- Low energy consumption during part load and full load operation.
- Inverter-driven twin-rotor 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
- Dual independent refrigeration circuits (from 1000 kW and up).
- 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.
- Touch Pilot control provides easy access to most unit operating parameters.
