Direct Cooled Ultra Low Temperature Freezer - China
price: 13500.00 Dollar US$
Application Principle
Our company developed the production of -135℃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℃ within three minutes, the minimum temperature is-150℃.
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 highoil vapor steam .
But pumping gas is difficult and time-spent and the residual gas will pollute the work piece, so the yield and quality of products will be influenced.
Ultra-low temperature freezer can solve all these problems.
