Rank® – Organic Rankine Cycle (ORC) Modules

What is Rank®?

Rank® equipment allows the production of electrical energy and useful heat using a low-temperature heat source, through the use of a turbine on an organic Rankine cycle (ORC), with the associated economic and environmental benefits.



Among the main applications of the Rank® ORC machines, we highlight the waste heat recovery and the utilization of renewable heat sources, with a special interest in cogeneration and trigeneration systems.

Rank® Technology – How a Heat Pump works

Most heat pump systems use the Vapour Compression Cycle, a thermodynamic cycle that produces heat from mechanical work (or electricity, on a regular basis), using a refrigerant as a working fluid. The Vapour Compression Cycle begins in the compressor, where the...
