Cryo H&I is a Korean cryogenic engineering company that builds cryopumps, cryocoolers, helium compressors and related cryogenic equipment, and runs an overhaul service for vacuum pumps used in semiconductor and display fabs. It was founded in 2020 after taking over the cryopump business of an earlier Korean vacuum company whose roots go back to 2003, and completed its own factory in Pyeongtaek in 2021.
Its in-house cryogenic R&D centre has developed 4 K, 20 K and 80 K cryocoolers (GM and pulse tube types), a smart helium compressor, the GENCRYO smart cryopump and liquid-nitrogen generators, including an explosion-proof 20 K cooler for hydrogen liquefaction.
