The Wärtsilä NOx Reducer (NOR) is optimized and validated for Wärtsilä medium-speed engines in terms of reliability, easy installation and meeting compliancy over whole lifecycle. It is available for both newbuild and retrofits and is compatible for operation on current and future marine fuels. Furthermore, with the Wärtsilä NOx Reducer, the overall performance of the engine and exhaust aftertreatment is optimized in terms of emissions reduction, noise abatement, and engine efficiency. Future engine modifications are easier with OEM SCR system. Wärtsilä provides IMO and EPA Tier III EIAPP certificates for a complete package of an engine and a SCR unit. Beyond IMO Tier III, other ultra-low NOx emission levels are also available. The SCR system can also be integrated with different silencers.
