Product details

Product Description:

Features & Functions:

Compressor

Compressor selection BITZER (Bitzer) HANBELL (Hanbell) Refcomp (Levin Beverly) imported famous brand semi-hermetic screw compressors, 5:6 ultra-efficient screw rotor design than most compressor energy efficiency high 20-30%, with as smooth and reliable operation, high efficiency, low failure rate, easy maintenance, etc. For the unit to run all or part of the load, each compressor can be step less or 75%-100% of multi-stage capacity control.

Semi-hermetic screw compressors for R22, R407c, R134a and other refrigerant working fluid type.

Shell And Tube Condenser And Evaporator

Condenser heat transfer from Germany, Japan imported and domestically produced different types of bras, brass outer surface processed int trapezoidal low fin tube, increasing the heat transfer area and enhanced heat transfer performance. Bras inner surface is smooth, so that the pressure decreases, and the ease of cleaning and maintenance.

Evaporator efficiency heat ex-changer with internal thread brass, brass outer surface the spiral smooth as well as the water side baffles non-short-circuit design, chilled water the mixed heat ex-changer efficiency.

Refrigeration Accessories

Frozen Accessories selection of the world's most well-known brands Danfoss (Danfos) ALCO (Viagra), SPORLAN (Sporlan), quality, performance.

Electric Control Systems

Electronic control system with high intelligence PLC, PC-class microcomputer control system. Responsive, precise control, with automatic loading and unloading, the multiple functions of the timer switch and record the cause of the malfunction can be remote or central monitoring.
