“Large-scale cryo-plant from liquid helium to superfluid helium temperature region,” a National Major Scientific Research Equipment Development Project, passed acceptance and its achievement appraisal in 2021.

China is now capable of developing its own large-scale cryo-plants, achieving cold capacity of kilowatt level at liquid helium temperature (-269 ℃) and hundred-watt level at superfluid helium temperature (-271 ℃). Large-scale cryo-plant with this capacity is an indispensable foundation for aerospace, hydrogen storage and transportation, helium resource exploitation, and Large Research Facilities.

The development of the equipment will not only meet the nation’s high-tech development needs, but will also boost advanced technologies in related fields.
