Features
1.  Cooling conditions: chilled water inlet / outlet temperature: 12 degree /7 degree; underground water temperature of 18 degrees /29 degree, well water temperature range: 15 degrees -33 degrees.
2,. characteristics:
A. Compressor: the use of the international brand semi closed 5:6 asymmetric double screw type heat pump special type compressor;
B. Heat exchanger: evaporator and condenser are efficient shell and tube heat exchanger, using imported plate material;
C. Control system: using SIEMENS control system, advanced PLC control technology, can accept the programming, perfect communication function;
D. The electrical system: SIEMENS, Schneider and other national brands of electrical components, waterproof type control cabinet;
E. Man-machine interface: Chinese-English man-machine interface, touch type liquid crystal display operation, simple procedures, one key to start, automatic operation;
F. Chiller maintenance: chiller  adopts integral design, compact structure, simple, strong corrosion resistance, with waterproof control cabinet, to ensure that the unit can be a long time in the outdoor, not easy to fade, corrosion.
G. The choice of environmental protection type R407C or R134a refrigerant.
