About us

Turboden, a Mitsubishi Heavy Industries group company, is an Italian firm and a global leader in the design, manufacture and maintenance of Organic Rankine Cycle (ORC) systems, highly suitable for distributed generation. ORC systems can generate electric and thermal power exploiting multiple sources, such as renewables (biomass, geothermal energy, solar energy), traditional fuels and waste heat from industrial processes, waste incinerators, engines or gas turbines. 

The company was founded in 1980 in Milan by Mario Gaia, Professor of Energy at the Politecnico di Milano and today Honorary Chairman of Turboden. In 2013 Turboden became part of Mitsubishi Heavy Industries group that strongly supports Turboden in the development of innovative solutions.

About us


As Prof. Mario Gaia has always liked to sketch his ideas on paper, one day he stylized a turbine that reminded so much the sail of an Oriental junk that he thought it couldn't be a coincidence. From that moment the turbine that reminds the Oriental junk is the mascot of the company. The traditional Oriental junk sail has a unique design, developed over the centuries, which is easy to use, so that a crew of few sailors can run a large ship; efficient, getting the most even from light winds; safe, the sail can be reduced quickly in case of strong winds, even by a single person. 
Its combined features well represent the aim of Turboden in creating efficient, safe, user-friendly as well as environmentally friendly products, as the payoff "clean energy ahead" remarks.
