WebbThe Selective Catalytic Reduction (SCR) system is an advanced exhaust after treatment system to reduce NOx. The engine controls the production of PM by increasing the combustion temperature thus limiting it within the permissible value. NOx increases while doing so, which is then controlled outside using a catalytic reduction process. WebbWe offer proven exhaust gas after treatment systems that meet the International Maritime Organization’s strict regulations for NOx emissions and fuel sulfur content, even in Emission Control Areas (ECA). Selective catalytic reduction (SCR) and exhaust gas recirculation (EGR) are highly effective technologies to minimize harmful NOx emissions.
