AUS40

AUS40 for marine ISO18611 applications is a blend of demineralised water and urea (urea content 40%). It acts as a reduction agent for SCR (Selective Catalytic Reduction) technology for NOx emission control.

AUS40 has a higher concentration of urea and is more efficient for larger vessels, while AdBlue® is more delicate and therefore more suitable for small engines.

Strong efforts have been made on the development of technology that can reduce such emissions effectively. SCR (Selective Catalytic Reduction) technology, using urea solutions as the reduction agents, is considered to be a key technology for abating NOx emissions in the marine sector. New and stricter emissions legislation will be implemented in the marine sector. Shallow and deep sea vessels, as well as inland vessels, will be equipped with SCR technology.

In so-called ECAs (Emission Control Areas), the emissions legislation is already in place and will be further enforced to wider areas.
