Helium liquefier unit employs a helium turbine reverse Brayton refrigeration cycle to obtain the corresponding refrigeration capacity. Helium liquefier uses a helium compressor to acquire high-pressure helium gases. Part of the high-pressure helium gases produces cold upon expansion in the turbo expander while the remaining high-pressure helium gases are cooled down stage by stage in the multi-stage heat exchangers. Finally, liquefied helium is acquired via a Joule Thomson throttling valve.,the liquefied helium is directly output as a product, this device is called helium liquefier.
