The FreeSpin™ In-line Turboexpander (FIT) provides a way to capture the energy lost in pressure reduction. Turboexpander systems with Calnetix’s Magnaforce™ motor generators extract kinetic energy from the pressure reduction at the various stages of gas processing and distribution and allow for the generation of electricity with no added pollution.
The FIT system consists of an integrated high-speed turbine and high-efficiency generator that runs on magnetic bearings in a hermetically sealed, lubrication-free unit to provide more efficient and reliable performance. The company offers standard or custom-engineered turboexpanders to meet customer requirements in any industry for applications, such as air separation, natural gas pressure letdown, geothermal power recovery, steam pressure letdown, gas liquification and distribution, chemicals and petrochemicals and gas turbine power recovery.
For more than a decade, Calnetix has been at the forefront of turboexpander technology, designing, implementing and manufacturing some of the most innovative solutions for expanders across many industries. The unique advantages of Calnetix’s FreeSpin™ system include the following:
