When it comes to cooling hydrogen down to -255°C, an expansion turbine
with magnetic bearings is the safest and most suitable solution.
Our turbines, which offer quasi-isentropic expansion, are the most efficient solution for hydrogen liquefaction.
When it comes to bringing hydrogen down to -255°C, an expansion turbine with magnetic bearings is the safest and most suitable solution.
The magnetic bearings are pressurized with hydrogen, thus eliminating any risk of outside air entering the system and causing an explosion.
Cryostar is the pioneer in expansion turbines with magnetic bearings. Our first model was released on the market in 1988, and we now have hundreds of models in service.
The turbine can be hooked up to a compressor integrated into the compression process or simply used as a brake (as on the MTC model) or a high-frequency generator (as on the MTG model.)
Our experts will be happy to help you choose the best solution for your situation.
CUSTOMER BENEFITS

Did you know?
World 1st expander with magnetic bearings has been developed by Cryostar 30 years ago.
APPLICATIONS
Hydrogen expanders are required to efficiently liquefy hydrogen.
Various liquefaction cycles are possible; our expanders are customized to be seamlessly integrated to your process.
POTENTIAL DEVELOPMENT
Cryostar’s range of magnetic turbo-expander/compressors is able to cover H2 liquefiers larger than 30 tpd.
Nevertheless, new applications with H2 will appear, and our engineers are ready to customize our turbo-expanders to fit your needs.
