Product Features

Optimised design

    Designed in full compliance with international standards. The design of the system adopts independent modularisation idea with high reliability. The technical idea of large temperature difference and small flow rate and computer-aided optimal control ensure that the unit is in the best operating condition under any working condition.

Superior performance

    The host adopts the international advanced semi-closed screw compressor, motor, compressor integration, no shaft seal leakage concerns.
    Single compressor or more than one compressor with start-up, shutdown round-robin control procedures, balanced load of various components, prolonging life.
    Single compressor or more units with multiple refrigeration circuits, one of the circuits to be serviced, the rest of the circuit can still operate normally, with mutual standby function.
    The compressor adopts unloading and voltage reduction to start, avoiding the impact on the power grid.

Wide range of applications

   Wide temperature range of applicable water source for the unit: 25-35℃.


Full range of safety and protection features

    Pressure protection: high pressure protection and low pressure protection device.
    Motor protection: loss of voltage protection, phase shortage protection, reverse phase protection, motor overheating protection.
    Anti-freezing protection: when the temperature of chilled water is too low, the unit stops.
    Safety valve protection: when the refrigerant pressure exceeds a certain value, the safety exhaust valve will open automatically.
    Various protections of the above equipment make the unit run safely and stably.
