LNEYA-36-Direct-Cooled Ultra-Low Temperature Freezer - 1

WUXI GUANYA REFRIGERATION TECHNOLOGY CO., LTD. There must be residual gas existing in high vacuum environment where the oil diffusion pump is used, and more than 80% is water vapor, oil vapour and other high-boiling oil vapor steam. But pumping gas is difficult and time-spent and the residual gas will pollute the workpiece, so the yield and quality of products will be influenced. Ultra-Low temperature freezer can solve all these problems. The working principle of direct-cooled ultra-low temperature freezer is placing a cooling coil up which cooling to -120°C at a vacuum chamber or pump entrance. Through condensation effects, rapidly collect the residual gas in the vacuum system, thus greatly shortening the vacuum time (can reduce 60% to 90% of the extraction time), to obtain a clean vacuum environment. Our company developed the production of -135°C direct-cooled ultra-low temperature freezer, using a single compressor, auto cascade refrigeration mode, DORIN compressors and refrigeration parts, environmental mixed refrigerant production. With specific cooling speed, high efficiency, low temperature, easy maintenance and other specific, rapid cooling, the temperature can be cooled to -120 °C within three minutes, the minimum temperature is -150°C. Refrigeration heating circulation air temp, control system Product application 1. Widely used in semiconductor equipment high & low temp. test. Cold or heat source for electronic equipment high & low temp, test; 2. Independent refrigeration circulation air unit; 3. Can continuous work, automatic defrost, defrost process won't affect the library temperature; 4. Modular design, easy spare replacement (if there are 10 units, only one spare unit is enough); 5. Solve frosting in evaporation system for frequent open & closed of the dor; defrosting process of evaporation system is not affected. 6. To build a set of high and low temp, constant room (according to the drawings provided, build a box like a building block, connect the electricity and water, then set the temperature to work).
