Selective Catalytic Reduction (SCR) systems are the part of your vehicle that converts harmful and hazardous gases (NOx emissions) into harmless nitrogen gas and water vapour. The SCR catalyst system is a reliable technology that enhances your fuel economy and requiring very little maintenance.

Many cars, trucks and heavy vehicles now use them as stock-standard in their design.

The Science of Selective Catalyst Reduction (SCR) Systems

Interested in the science behind SRCs?

The SCR catalyst is integrated to the oxidation catalyst. This transforms the unburnt hydrocarbons (HC) and the carbon monoxide (CO) within the particulate filter (DPF) installed on your vehicle. It works through a chemical additive made of ⅔ water and ⅓ technical urea (AdBlue). Additives are injected directly into the SCR catalyst. Due to the contact with the exhaust gas and the high temperature it turns into ammonia. This thereby neutralizes the NOx and reduces it to a mixture of oxide and steam. Amazing!

Clean & Regenerate Your SRC System Before You Forced Into A Replacement

If you see any of these symptoms you should clean your SRC immediately.

  • Fuel efficiency suddenly drops
  • Your vehicle loses power and won’t accelerate like it used to
  • Failed emissions test
  • Strong exhaust odour
  • Your engine light comes on

If you start to see any of the above symptoms its possible that your SCR is starting to fail. But there’s hope if you spot it early.

First you’ll see a progressive decrease of the operating capacity. Continued use of your vehicle under these conditions will lead to instant and irreversible damage caused by metals (such as copper and zinc) and other pollutant substances. Unfortunately, once this occurs the only solution is to replace the SCR catalyst.

If you get to us before this stage we can save your SRC. Our Flash Cleaner Machine regenerates your SCR back to its original efficiency. We flush out the areas that have have become clogged and remove any obstructions which returns your SRC back to full operating health.

Where all the other cleaning systems fail, our Flash Cleaner Machine can intervene successfully. In a relatively short time your vehicle will be back on the road.
