    Specification :

    Superior performance
    1.The main International advanced semi-closed screw compressor in which electric
    motor and compressor are organically integrated to ensure no leakage of the shaft
    sealing.
    2.Control programs for start and stoppage are applied to double or multiple compressors so as to balance the load and extend the service life of each component.
    3.Several refrigeration circuits are provided for double or more compressors. When one circuit needs maintenance, other circuits can work properly as alternative circuits.
    4. The compressor is started with unloading and decompression to avoid the impact to the power grid.
    5.The vortex and propeller of the compressor is designed to ensure extremely low noise.
    6. H/W structural design, favourable thermal radiation.
    7.Heat exchanger has the national pressure vessel certificate.
    Comprehensive Security Protection
    1.Pressure Protection: high pressure protection and low pressure protection
    2.Electric Motor Protection: lost voltage protection, incomplete phase protection, reverse phase protection, overload protection, overheating protection, Anti-freezing Protection: the unit shall be stopped when the freezing water temperature is too low.
    3.Safety Valve Protection: when the refrigerant pressure exceeds the given value, the
    safety relief valve will be automatically started.
    4. All the aforementioned protection can ensure the unit a safe and stable operation.
    Easy Installation
    1.The unit is so structurally compact that it only covers a little floorage to save the space of the machine room.
    2.Prior to the shipment, flow switch has been equipped inside the unit.
    3.Due to the little vibration of the unit, the base can be provided with no anti-vibration measures.
    4.The pipes of the evaporator and the condenser are only required to be connected in time of installation.
    The feature of Screw Compressor
    1.Fluorine-resistant electric motor of high efficiency and reliability imported from France
    2.The latest 5-6 asymmetrical gear form of the third generation
    3.Four-section volume control continuous capacity adjustment unloading control system
    4.Equipped with German FAG and Swedish SKF high-precision bearing
    Shiwoer effect oil separator
    5.Low vibration and noise
    Microcomputer Control
    1.German SIEMENS PLC, human interface with whole Chinese character display; Italian CareL text indicator.
    2.Automatically monitor the outlet temperature of freezing water and adjust the compressor through PLC autocontrol slide valve which can save energy.
    3.Directly and clearly display water temperature points and operation times through PLC;
    4.Automatically record and store the recent fault alarm and the time and prompt the suggestions on the fault treatment;
    5.The original parameters such as inlet and outlet water temperature, the position of slide valve, each protection point of the unit and pressure can be rectified (via password) in accordance with the actual needs.
    Operation Status Display (PLC)
    1.The operation status of the unit is displayed in the animated manner, including the operation of the compressor, the flow status of refrigerant, water flow and temperature display;
    2.Gain a thorough understanding of the operation of the unit.
    Original Refrigerating Components and Electric Apparatus
    Relay, heat protector, expansion valve and pressure controller; the drier-filter adopts the world famous brand product, which greatly increases the reliability of the whole machine.
    Supply the Total Cooling Water System
    1. Supply the total cooling water system design and the main parts of the system,
    2. More choices for the brand of the parts of the chiller,
    3. Give Best plan for your industrial cooling water system project, including the selection, project drawings.
