MarineBlue40 (Aqueous Urea Solution 40%)
Aqueous urea solution 40 or AUS 40 is the other type of DEF usually used for ships. It reduces Nitrogen Oxide (NOx) emissions from vessels and sometimes from the other diesel engine exhaust systems. Marine Urea is injected into the diesel engine exhaust systems and reacts with nitrogen oxide gas emissions. So this solution converts the harmful emissions to water vapor and Nitrogen.
