FreeSpin In-line Turboexpander™
An oil-free, hermetically sealed solution for reducing pressure in gas How FreeSpin In-line Turboexpanders™ Work processing and distribution systems while generating clean power. 1 The pre-heated high-pressure gas flows into the turboexpander.
The Calnetix FreeSpin In-line Turboexpander™ (FIT) provides a way to capture the energy wasted in pressure reduction. 2 The gas expands through the radial turbine wheel. Turboexpander systems with Calnetix’s Magnaforce™ motor generators extract kinetic energy from the pressure reduction at 3 The low-pressure gas exits the FIT and is ready for delivery to residential and commercial users. the various stages of gas processing and distribution and allow for the generation of electricity with no added pollution. 4 The energy wasted during the pressure reduction process is recovered by the FIT and converted to electrical power.
The FreeSpin In-line Turboexpander system consists of an integrated high-speed turbine and high-efficiency generator that 5 Any excess high-pressure gas not directed through the FIT is expanded by the conventional pressure regulator. runs on magnetic bearings in a hermetically sealed, lubrication-free unit, and provides more reliable performance. 6 The produced electricity enters the Vericycle™ Bi-directional Power Electronics Unit, which can be programmed to Its high-speed Magnaforce™ motor generator has variable speed and load capabilities and provides greater power density in a specific power requirements. smaller footprint than conventional systems.
