The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, screw, scroll, or other expander), and then through a condenser heat exchanger where it is finally re-condensed.

The Organic Rankine Cycle's principle is based on a turbogenerator working as a conventional steam turbine to transform thermal energy into mechanical energy and finally into electric energy through an electrical generator.

Opteon™ MZ working fluid is the best choice for organic Rankine cycle systems.

The Organic Rankine Cycle (ORC) is a thermodynamic process that generates electricity and heat even at lower temperatures: Instead of water, another organic process medium with a low evaporation temperature is used for the steam power process.
