A Mark Of Quality

SCR (Selective Catalytic Reduction) is a crucial component of EATS (Engine After Treatment System), aimed at reducing NOx (Nitrogen Oxides) emissions in Diesel engines. A reducing agent called AUS 32, also known as AdBlue® in Europe and DEF (Diesel Exhaust Fluid) in North America, is used in SCR Catalyst. This colourless, non-toxic liquid, comprising 67.5% demineralized water and 32.5% technical grade urea, efficiently converts nitrogen oxides into nitrogen and water. ISO 22241 (BS 17042 in India) is the global standard for manufacturing, testing, storage, and handling of AUS 32. AST Blue complies to BS17042 standards and is tested for compliance in ARAI (Automobile Research Association of India)

AST Blue quality directly affects the efficiency of the SCR system, which, in turn, impacts your vehicle’s engine performance. High-quality AST Blue ensures that the SCR catalyst operates at its best, enabling effective emission control without compromising engine power. The SCR system relies on a precise chemical reaction between AST Blue and the NOx in the exhaust gas. Using high-quality AST Blue ensures that this reaction occurs as intended, maintaining the SCR system’s efficiency and preventing malfunctions.
