What Is Adblue ®?

Contact Us Products

AdBlue® is a high purity operating fluid, used in the emissions removal systems of diesel engined vehicles and equipment. Chemically speaking AdBlue® is a 32.5% solution of Urea in purified water.

The AdBlue® is stored in a tank on the vehicle and from there dosed automatically by the ECU directly into the exhaust gas at a rate in relation to the amount of Nitrous Oxides (NOx) being produced by the engine.

Adblue Diesel Exhaust Fluid

Following mixing, the AdBlue® and exhaust gas mixture passes into a catalyst system where a chemical reaction takes place converting the NOx to harmless Nitrogen and Water, which are then expelled from the end of the exhaust.

During the reaction the AdBlue® is consumed and needs to be replaced by refilling the tank periodically. AdBlue® consumption is related to engine load, engine size, travelling terrain and temperature.

Adblue, The Pure Diesel Exhaust Fluid

Since January 1, 2005, new HGVs sold in Europe have been required to comply with the Euro 4 emissions standard which halves the emissions limit permitted under Euro 3. A drastic reduction in Nitrogen oxide (NOx) and soot particles in lorry and bus exhaust fumes.

In order to meet the environmental requirements of the Euro 4 and Euro 5 standards (Euro 5 is a stricter standard which is being introduced in 2009) on polluting HGV emissions, the vast majority of manufacturers have chosen SCR (Selective Catalytic Reduction) technology to reduce their nitrogen oxide emissions. This involves incorporating the urea into an aqueous solution called Adblue.

What Are The Advantages?

There are many advantages of SCR technology: around 85% of nitrogen oxide is converted into water vapour and harmless oxides thanks to the use of Adblue in the vehicle's exhaust system. This is a weighty argument at a time of high fuel prices and provides an additional asset when it comes to protecting the environment as it reduces CO2 emissions.


  • A secure investment in order to meet future anti-pollution standards.
  • SCR works throughout Europe with varying qualities of diesel fuel.
  • Designed to last as long as your vehicle, SCR doesn't require any maintenance.
  • No impact on frequency of maintenance and oil changes.
  • Reduces fuel consumption: a lorry using SCR technology burns between 2% and 5% less fuel than a similar model without SCR technology.
