Air cooling unit For semiconductor testing

It is used to cool the gas (non corrosive) or recover it as non corrosive gas by condensation and liquefaction.

Pressure resistance of gas heat exchange system: 25bar; The temperature range is – 40 ℃ ~ – 75 ℃, which can meet different temperatures;

The secondary subcooling technology is adopted, with rapid refrigeration and low refrigeration temperature;

Semi closed piston compressor, scroll flexible compressor and fully closed piston compressor of imported brands are adopted;

The evaporator adopts casing heat exchanger, which has the advantages of small volume, long residence time and high efficiency;

Danfoss expansion valve and Emerson electronic expansion valve are adopted, with high temperature control accuracy;

Siemens plcs7-200 / 300 and lneya touch screen display are used for automatic control operation;

The whole machine is installed. The system has been tested in the factory. Users only need to install the refrigerant pipeline and cooling water pipeline to run;

Factory test: each refrigeration unit shall be tested with load in the factory for no less than 12 hours;
