1. Compressor

German semi-hermetic twin screw compressor has longer bearing life and ensures long running.

Press built-in three-stage oil separator, long-term 10 m oil filter, lubrication effect improved significantly

Four energy control valves can be satisfied, four stages of sectional energy regulation, 25% - 100% stepless energy regulation.

The suction position of the special energy saver can be changed with the energy regulating valve to save more energy.

A variety of refrigerants are available. Besides R22, environmental friendly refrigerants such as R407C are also available.

2. Condenser and Evaporator

Use of High Efficiency Horizontal Shell-and-Tube Heat Exchanger

The product meets the requirement of national pressure vessel

Imported high-quality tube sheets and threaded copper tubes are used as raw materials to greatly increase the heat transfer efficiency of refrigerant and water.

The product flow structure is simple, heat exchange is stable, maintenance is convenient.

The product has the advantages of beautiful appearance, small volume, large heat transfer and low failure rate.

3. Microcomputer Controller
