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.
The “cartridge” design of the rotor assembly allows access to the rotating element without re- moving the expander casing and its cold box extension.
For easy maintenance, a spare “plug-in unit” (expander without casings) allows customer to change all internal parts within a minimum of time and with maximum reliability.
Diffuser design allows low radial loads at all operating flows.
Variable oil brake is used to adjust the cold production
