What is SCR?

Selective Catalytic Reduction is a means of converting Nitrogen Oxides (NOx) into Nitrogen and Water, using an Atomised Injection of urea with the aid of a Catalyst.

How is it achieved?

The reduction is called “Selective” as it is only targeting the NOx emissions using the reagent and Catalyst.We take the Raw NOx Value and Reduce it to the Target Value (500mg to 50mg – 90% Reduction)This is achieved through:

  1. Controlled Atomising Injection of Urea – Dosing
  2. Efficient Mixing in the Exhaust Stream – Static Mixers
  3. Coated ceramic Catalyst Surface – Reactor
