Agriemach SCR System Overview

Technology Explained

Understanding SCR & NOx

What is NOx?

Nitrogen Oxides are a hazard to human health. Scientific evidence links NO₂ exposure — from 30 minutes to 24 hours — with adverse respiratory effects including airway inflammation. Ozone is formed when NOx and Volatile Organic Compounds react in the presence of heat and sunlight, affecting anyone that comes into contact with them.

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. The process specifically targets NOx emissions using the reagent, reducing raw values to target outputs — achieving up to 99% reduction (500mg to 50mg).

How is it Achieved?

  • Controlled Atomising Injection of Urea — Dosing
  • Efficient Mixing in the Exhaust Stream — Static Mixers
  • Vanadium Coated Catalyst Surface — Reactor
  • System Overview — Monitoring and Control via PLC
System Intelligence

PLC Control & Monitoring

The PLC (Control Panel) monitors and controls the entire system in real time, ensuring optimal performance and regulatory compliance across all operating conditions.

Established 1976

Experts in NOx Reduction

Agriemach have been specialists in the emissions field since 1990. It is important that when new legislation is introduced, that operators do not get misled and find themselves falling into a money pit of extras after the project has started. We offer complete solutions, services and aftersales support.

What Our Customers Say

“

I would like to say thank you for your help on this project. Things have not always been easy, and we have had a few challenges, but you — both corporately and personally — have conducted yourself with integrity at all times and have made things a lot less painful than they could otherwise have been for us.

In a few years' time I am sure the birthing pains will have been forgotten and the investment we made will have delivered the anticipated benefits — and I am confident that the level of emissions we put into the atmosphere will not give anyone cause for concern.
