With the aid of ammonia or urea, Selective Catalytic Reduction (SCR) converts nitrogen oxides, also referred to as NOx, into N2 and H2O. Diesel Exhaust Fluid – a solution with 32.5% urea and 67.5% de-ionized water is sprayed into SCR system through a dosing unit and an injector. Efficient application of SCR technology requires a specifically adapted dosing system.
