Spirax Sarco TR Steam MicroTurbine


The Spirax Sarco TR Steam MicroTurbine range generates electrical power via the function of steam pressure reduction. The solution allows you to generate and supplement your own electrical demands by harnessing the energy released by the resulting pressure drop.

The generated electrical power is primarily used for local plant consumption; however, any excess can be supplied back to the grid. Features include;

- Suitable for saturated or superheated steam

- Compact design makes retrofitting into existing steam plant possible

- Supplied fully assembled and tested – ready to install


Typically installed in parallel to a steam pressure reducing station, up to 700 kW* of electrical power can be produced – with the outlet steam still available for plant utilisation.

How does it work?

The TR MicroTurbine is specifically designed for use in steam systems. Coupled to a matching electrical generator, electricity is produced as steam turns the turbine blades.

The back-pressure turbine will convert the required amount of energy to lower the steam pressure, so the steam emerging on the downstream side can still be used by the process.
