✓ The Technology (Diesel Exhaust Fluid-DEF)

"SCR" is the name of a post-combustion technology treatment for diesel vehicles, which allows them to reduce their harmful emissions of NOx (nitrogen oxides). SCR stands for Selective Catalytic Reduction. This technology requires the use of a reagent called Ad Blue®. Most engine manufacturers use this technology to meet the requirements of new legislation (euro V/VI) on NOx (Nitrogen oxides) emissions.

✓ How does AdBlue® work with SCR technology 

AdBlue® is injected from the vehicle's dedicated AdBlue® storage tank into the exhaust system, which is in front of the SCR catalyst, but downstream of the engine. As it is heated in the exhaust, the AdBlue® changes into ammonia (NH3) and carbon dioxide (CO2). When the nitrogen oxide (NOx) gases from the exhaust pipe react inside the catalyst with the ammonia, the harmful NOx molecules in the exhaust are converted into harmless nitrogen and water, which is released into the atmosphere as steam.

✓ What We Do

Our product (re-agent) is called "Siya Blue"; is locally produced under licence and according to ISO standards.

Our Market - All diesel engines with factory fitted SCR (Selective Catalytic Reduction) technology. Passenger, Commercial, Industrial & Mining.

Do I need to maintain my vehicle's SCR system: The SCR system is installed in your vehicle by the manufacturer and works automatically. You do not need to maintain or modify it. AdBlue® is automatically injected into the exhaust depending on your vehicle  engine's load. As for adjusting the consumption, the level of AdBlue® consumption is determined by the vehicle manufacturer.
