The Rank® equipment allows the production of electrical energy and useful heat using a low-temperature heat source, with the associated economic and environmental benefits.


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