Ry Direct Cooled Ultralow Temperature Freezer - China

Introduction 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.

The working principle of direct-cooled ultra-low temperature freezer is placing a cooling coil up which cooling to-120℃ 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 .
