The SLJ series ultra-low temperature refrigerator utilizes a refrigeration coil that can reach below -120°C, placed in the vacuum chamber or the pump port of the oil diffusion pump, and quickly captures the residual gas in the vacuum system through the low temperature condensation effect on its surface. Thereby, the vacuum time is greatly shortened (60~90% of the pumping time can be shortened) to obtain a clean vacuum environment, which is especially suitable for the semiconductor industry. Guanya ultra-low temperature freezer adopts a new type of non-toxic ring refrigerant, which can replace the current liquid nitrogen freezing method. Compared with the traditional cooling method, the refrigerant can be recycled, which greatly reduces the cost of the enterprise. Mainly used in vacuum coating (sputtering, evaporation); semiconductor (wafer processing) and other industries
