Compact gas engines for continuous operation in power- or heat-led systems

Important facts about the product range and applications

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 optimised 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.

Milestones of agricultural technology

Milestones of agricultural technology

As a manufacturer and developer of diesel engines, MAN has been closely associated with agricultural engineering since the early 1920s. The innovative engines were initially installed in the company’s own machines – from motorised ploughs to the company’s tractors – but were later increasingly sold to other manufacturers. Today, MAN engines can be found in agricultural machinery from a wide range of manufacturers and are in particular used in areas with high demands on performance and efficiency.

MAN engines in wood gas CHP units

MAN engines in wood gas CHP units

In times of nuclear and coal phase-out, the question of a safe and clean energy supply is increasingly in the focus of power producers. MAN Engines has been offering solutions in this sector for decades, supplying CHP manufacturers with robust, clean gas engines. The use of special gases such as biogas and sewage gas has proven to be particularly sustainable and popular. But with wood gasification, a lesser-known technology has recently come back into focus. Here, too, MAN Engines and its partners serve a still small but steadily growing market with powerful gas engines.

Modular exhaust gas aftertreatment system for biogas CHP units

The 44th German Emission Control Act (Bundes-Immissionsschutzverordnung, BImSchV) has noticeably restricted the limit values for biogas CHP unit emissions. Operators are facing particularly strict emissions limit values for nitrogen oxide (NO_x). With its modular exhaust aftertreatment system, MAN Engines has been prepared for the new limit values. The project about minimising NO_x emissions during biogas CHP unit operation has been carried out by the Technical University of Munich (TUM).
