Gas liquefaction

HUALENG Stirling cryocoolers operate on the reverse Stirling cycle. They achieve cooling through four processes in a closed working medium system (typically helium): isothermal compression, isochoric heat regeneration, isothermal expansion, and isochoric heat regeneration. The cryocoolers can stably provide a cryogenic environment of 80K to 120K, meeting the liquefaction requirements of various gases.
