Product Details

MAN Engines offers low-pollution gas engines for purely electrical power generation and cogeneration. The power range extends from 37 kW to 750 kW with natural gas and from 68 kW to 750 kW with special gas (biogas, landfill gas, sewage gas). The MAN engines developed especially for the application with natural and special gas excel through their ultimate reliability and highest energy efficiency. Thanks to their optimum combustion process, they achieve best overall efficiencies in excess of 90 percent.
