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

The performance of embedded high-speed microprocessor is much higher than that of single-chip computer used in the same industry.

Equipped with high stability memory, 512K program storage capacity, 128K power-off data storage capacity, stable storage data and will not lose

The chip has compact structure, low calorific value and strong anti-interference ability.

It has the function of timing switch, fault inquiry and fault alarm.

Using 485 communication transmission technology, the transmission data is far away and the signal does not attenuate, up to 1200 meters.

With multi-controller on-line control function, reserve PC computer monitoring function

With online multilingual switching function

Touch screen full graphical man-machine interface, providing password protection function, easy to operate
