AUS 40  or Aqueous urea solution 40  is the type of  diesel exhaust fluid (DEF) usually used for ships. It reduces Nitrogen Oxide (NOx) emissions from vessels and 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. It can also be described as AdBlue for ships.

Benefits of using  AUS40 DEF?

• Decrease the DEF emissions or mono-nitrogen oxide from diesel engines
• Allow You to introduce your company as an eco-friendly provider
• Reduce fuel consumption
• Decrease fleet costs
• Optimizes engine performance
• Operate more efficiently
