Wärtsilä NOx Reducer (NOR)

The Wärtsilä NOx Reducer (NOR) is an emission after-treatment system based on the Selective Catalytic Reduction (SCR) technology for Nitrogen Oxide (NOx) reduction. The system is compliant with various NOx emission reduction needs, such as the IMO Tier III rules.

The NOR is optimized and validated for Wärtsilä medium speed engines in terms of reliability, flexibility and size. It is available for both newbuild and retrofits and is compatible for operation on both distillate and heavy fuel oils.
