Screw Cryogenic Refrigerator

The original Italy "Lai Fukang", Japan "Kobelco", "Taiwan Fu Sheng" "Hanzhong" semi hermetic screw compressor.

Efficient living valve energy control, realize automatic classification or stepless adjusting energy.

Balance design of statically stable operation.

The moving parts of strict processing, repair cycle is long, trouble free operation for more than 40000 hours.

High efficient oil separator, exhaust with the oil is less than 1.5%

New efficient evaporator / water cooling type cooler:

The latest high performance of inner grooved copper tube, enhanced heat transfer effect, more energy efficient. CAD/CAM processing technology and finished, the structure is compact.

A refrigerant distribution uniformity, improve the heat transfer efficiency.

Heat exchanger bundle of the U type structure, can be integrally drawn out for cleaning internal scale, convenient maintenance. In the evaporator, convenient to oil, improve the reliability of the service life of the compressor and the system.

Easy installation

The unit has the advantages of compact structure, small occupation area, light weight, easy to carry.

Balanced operation safety, small vibration, no need of complex foundation, simple installation.

Various performance tests have been completed before leaving the factory, and the completion of the terminal, reduce installation time and cost.

Reliable operation

Motor using the world's most advanced Japan PTC thermal protection, and make the protection more sensitive, more reliable.

Interlocking control can realize water system and unit.

Compressor unloading step-down start, small startup current.

The unit adopts multi refrigeration loop

Accurate control

PLC programmable controller, man-machine interface, full Chinese display.

PLC uses a closed loop and direct digital control (DDC), can realize the full process, full automatic computer control regulation, make the group of control more accurate and reliable

Cold water temperature automatic monitoring, automatic control valve for unloading through PLC, the automatic adjustment of compressor in the small temperature range, reduce energy consumption.

The start-up of the unit, through a microcomputer climbing control, quickly reach full load.

Has the function of self diagnosis, in some parameter approaches a limit value, taking certain protective measures, and alarm, the unit is not damaged, and the day to reduce unplanned downtime.

Automatic recording alarm storage unit fault in recent ten times and the time, and issued therefore prompt.

The function of automatic protection unit: compressor low suction pressure protection, compressor discharge pressure is too high to protect the ultra low temperature cold water, cold water protection, cooling water protection, motor overload protection, motor overheating protection, power failure protection (overvoltage, undervoltage, lack of phase, phase sequence wrong etc.), anti repetition priming.

Function control panel display:

The running status of the host, chilled water pump, cooling water pump, cooling water outlet temperature, suction pressure of the compressor, the compressor discharge pressure, exhaust temperature of the compressor, the compressor cumulative running time, unloading state, time display function, fault display function.
