Remedy for reducing nitrogen oxide emissions. High quality reagent Vitex Blue AUS 32 NOx is used as an additional working fluid in diesel engines which are equipped with SCR system — it is selective catalytic Converter, designed to reduce the emissions of the nitrogen oxides (Nox). Using a new generation reagent German Power Additives makes the ammonia chemical reaction with nitrogen oxides of emissions. Due to this reaction, forms the non-hazardous nitrogen and vapour. The environmental standards (Euro 4/Euro5) are achieved because of the reagent’s injections.
