500kW Biogas Generator With MAN Industrial Engine
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.
MAN engines for natural gas and special gas (biogas, landfill gas, sewage gas) ensure security of supply – they have been thoroughly tested and optimized in field trials. The engines have proven themselves through their robustness, combined with high operating hours in peak-load and continuous operation, in the agricultural and municipal sectors, in hotels and hospitals as well as in numerous other industries. The long service intervals and high service life of MAN gas engines ensure low total cost of ownership.
