Stirling engine production

Like no other energy converter, Stirling engines are able to convert solar energy and renewable fuels in a low-emission and climate-neutral way. They will initially establish themselves where they are not in competition with conventional petrol and diesel engines.
At the company's site in Potsdam, a special 2-cycle Stirling engine (2-ZGM-1 kW) is manufactured that runs on a renewable fuel.
