Features
1. Compressor: adopt international brand semi closed 5:6 non symmetrical double screw type air cooled special type compressor.
2. Heat exchanger: evaporator use high efficient shell and tube heat exchanger, condenser use high efficiency copper pipe+hydrophilic aluminum fin; with high pressure, high heat transfer efficiency, maintenance free, long service life, etc.;
3. Control system: using SIEMENS control system, advanced PLC control technology, can accept the programming, perfect communication function;
4. The electrical system: SIEMENS, Schneider and other national brands of electrical components, waterproof type control cabinet;
5. Man-machine interface: Chinese and  English man-machine interface, touch type liquid crystal display operation, simple procedures, one key to start, automatic operation;
6. Chiller maintenance: chiller adopts integral design, compact structure, simple, strong corrosion resistance, with waterproof control cabinet, to ensure that the unit can be placed outside the long-term is not easy to fade, corrosion.
7. The choice of environmental protection type R407C or R134a refrigerant.
