This product is a liquid-cooled SCR dosing unit for NOx reduction in close coupled applications. The Selective Catalytic Reduction (SCR) technology is a key technology in the area of NOx-reduction to meet future emission legislations especially in Europe and in the US. The Deka SCR injector delivers Aqueous Urea Solution (AUS32, Adblue) into the diesel exhaust stream. Ammonia (NH3) is formed out of this solution by means of thermolysis and hydrolysis. Ammonia then serves as a reductant to minimize the NOx-emissions in a dedicated SCR catalyst.
