Cryogenic refrigeration technology is one of the core technologies of refrigeration equipment, and it can control the temperature up to cryogenic temperatures of 8K (-265 degrees) using Gifford-McMahon refrigeration technology, and can be applied in various fields of cryogenic experiments as well as cryogenic pumps.

Various line-ups are built according to the heat capacity of the first and second stages.
Development of high-capacity ultra-low temperature chiller for hydrogen liquefaction.
