Cryostar has a unique experience in the design of these TFC, with the first unit built in 1991 and more than 50 TFC in operation sold to the major gas companies.
Turbo expander with cryogenic compressor and variable oil brake mounted on a common shaft.

Diffuser design allows low radial loads at all operating flows.
Variable oil brake is used to adjust the cold production
