SCR_300x225Catalytic after-treatment of the exhaust gas breaks down harmful NOx into harmless nitrogen and water. 

A reducing agent is injected into the exhaust gas flow upstream from a catalytic reactor. Together with the catalyst, this agent causes the breakdown of the NOx.

NOX reduction up to 97%

With SCR, the engine can operate at partial and full load and maximum efficiency. With this technology a NOx reduction ratio of up to 97% is achievable.

MAN has developed a standardized portfolio of SCR systems together with leading catalyst developers and producers, respecting the experience of several successful projects.
