The High Purity Helium Liquefier utilizes a helium turbo-expander Brayton refrigeration cycle to achieve superior cooling performance. The process starts by obtaining high-pressure helium gas through a specialized compressor. A portion of this gas undergoes expansion cooling within a turbo-expander, while the rest is progressively cooled through multi-stage heat exchangers.
Finally, liquid helium is produced by throttling through a Joule-Thomson valve, and the high-quality liquid helium is outputted directly. This sophisticated refrigeration equipment is essential for high-tech industrial and scientific applications.
The system integrates several high-precision components to maintain the Brayton refrigeration cycle:
