What is AdBlue ?
- AdBlue is the trade name for Aqueous Urea Solution 32,5% (AUS32).
- AdBlue is a clear, non-toxic liquid. It is harmless in handling and does not damage the environment.
- AdBlue is used in cars running with diesel engine, where in catalyst SCR (Selective Catalytic Reduction) is implemented.
- AdBlue is based on Urea ( highly pure for automotive needs, so called Automotive Urea), the same Urea which is used for the fertilizers in agriculture world.
- AdBlue is sensitive to extreme temperatures, both hot and cold. Its recommended storage temperature is from -11°C to 30°C. It starts freezing, if its temperature falls below -11°C.
- Yet, AdBlue is not harmed by the freezing process and once thawed retains its liquid state and quality. In areas where the temperature is frequently > 30°C, it is necessary to ensure that the solution is not stored in direct sunlight
AdBlue nowadays is used in:
- most of the trucks/vans produced in the World ( due to diesel engines),
- most of the diesel passengers cars with big diesel engines ( Audi, BMW, Mercedes-Benz)
- in big new ships
- in trains
- in energy producing heating plants
- soon in airplanes
What is AdBlue/SCR technology?
SCR technology is implemented to reduce harmful gases in diesel engines and meet the EURO4, EURO5, EURO6 and further EURO7 standards of emissions. These standards are required in many countries all over the World: whole Europe, USA, Africa, Australia, Singapore, Israel and many others.
When car/truck/van/or any other engine have implemented SCR technology, then the use of AdBlue is obligatory from legal point of view.
AdBlue in the catalyst is spread over the harmful gases (NOx – nitrogen oxide) and by chemical reaction transforms the harmful gas into harmless nitrogen and vapour – the components of atmosphere.
