AdBlue

AdBlue is a Diesel Exhaust Fluid (DEF) used in vehicles with Selective Catalytic Reduction (SCR) technology. This technology is found in cars, vans, trucks and buses to reduce the emission of nitrogen oxides (NOx). AdBlue is a 32,5 % solution of high-purity urea in de-mineralized water. Product complies with ISO 22241 standards and CEFIC guidelines for NOx reduction additives.

AdBlue is injected in the exhaust phase before reaching the SCR catalyst. A reaction takes place between the NOx and the Urea, converting the Nox into unharmful nitrogen and water vapor.

Handling instructions

AdBlue is not a toxic, poisonous or dangerous liquid. However, there are some points to take into account when working with it.

• Never add or mix extra water content to the AdBlue mixture
• Do not add the AdBlue to your diesel, it is not a fuel additive
• The AdBlue has to be kept pure and can not be contaminated with other components
• Do not use any IBC, drum, jerrycan or other container that was used for other chemicals before
• Do not clean the IBC’s or other containers you’re going to use with microfiber cloth. The fibres of the cloth can damage the nozzles of the SCR system
• Keep out of direct sunlight or away from extreme temperatures, the urea in the AdBlue starts to decompose at 60°C
• Prevent freezing. It has a freezing point of -11°C
