Aqueous urea solutions AUS 32, AUS 40, AUS 20

Aqueous urea solutions AUS 32, AUS 40 and AUS 20 are NOx reducing agents.

Aqueous urea solution AUS 32 reduces nitrogen oxide emission from auto exhaust system. The solution is injected to diesel engine exhaust systems before selective reduction catalyst, consequently due to the solution reaction with nitrogen oxide gasses emissions are converted to water vapour and nitrogen. This technology optimises engine performance by reducing particle emission and maximizing fuel energy generation. Another significant effect of the process is reduced fuel consumption (on average 5 %).

Aqueous urea solution AUS 40 reduces nitrogen oxide emission from vessel or diesel engine exhaust system. The solution is injected to diesel engine exhaust system before selective reduction catalyst, consequently due to the solution reaction with nitrogen oxide gasses emissions are converted to water vapour and nitrogen.

Aqueous urea solution AUS 20 is used for removal of NOx formed from smoke stumps spreading/spraying in the incineration system, moreover as anti coniferous diseases (root sponges) spread.
