AdBlue® is a soluble colourless solution that looks like water. In Europe& Asia Pacific, AUS 32 solution is generally known by the trademark AdBlue; in North America, Diesel Exhaust Fluid(DEF). In Latin America AUS 32 has several names, but in Brazil, it’s known as ARLA32.
It is composed of 67.5% distilled water and 32.5% high grade urea. The composition of AdBlue® makes it a biodegradable, non-explosive, non-toxic and non-flammable liquid. This liquid reduces the carbon footprint of your car and is used in many vehicles, from trucks to tractors, to vans and to cars. Heavy goods vehicles were the first to be affected by the European regulation, being equipped with AdBlue® tanks since 2005. AdBlue® meets the criteria of ISO 22241-1 to 4 and is registered as a trademark by the VDA ( German Association of the Automotive Industry). We KELAS was the first company in China who is permitted to use this trademark by the VDA.
AdBlue® is used by modern SCR (Selective catalytic reduction) systems as a way to reduce the emissions of nitrogen oxides of cars. Since 2005 European standards have aimed at reducing the emission of pollutants from diesel cars by imposing limits for the emission of nitrogen oxides. The European standard Euro VI in force since September 2014 has reinforced these limits in order to reduce the impact on the environment of pollution produced by diesel vehicles. Many car manufacturers have since chosen to equip their cars with the SCR system, which is a technology of post combustion exhaust processing that converts the harmful molecules of nitrogen oxides into a catalyst and allows the reduction of the level of pollution of diesel cars! In this way AdBlue® powers this SCR system by circulating in an independent tank to that of the diesel.
