Helium Turboexpanders
Helium Turboexpanders for Cryogenic Applications
PBS helium turboexpanders are intended for the efficient expansion of inert gases (helium, nitrogen, argon, etc.) in their liquefaction processes. Precise regulation of power and cooling effect is ensured thanks to the integrated eddy current brake. Modular design allows easy adaptation to specific operating conditions, and compact design ensures simple integration into cryogenic systems.
