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.
 
SCR technology is implemented to reduce harmful gases in diesel engines and meet the EURO4, EURO5, EURO6 and EURO7 standards of emissions.
 
These strict standards are required in many countries all over the World.
 
When car/truck/van/or any other engine have implemented SCR technology, then the use of AdBlue is obligatory.
 
AdBlue in the catalyst is spread over the harmful gases and by chemical reaction transforms the harmful gas into harmless nitrogen and vapour – the components of atmosphere. 
 
AdBlue is based on Urea, highly pure for automotive needs, so called Automotive Urea - TGU.

 
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.
 
 
Since AdBlue is highly corrosive that’s why all devices for dispensing, storage and production of AdBlue that have contact with the liquid must be made of materials intended for AdBlue contact. The list of these materials is set out in the restrictive ISO 22241-1/ -2/ -3/ -4 standards.

 
Our devices always meet restrictive ISO 22241 standards.
 
AdBlue nowadays is used in:
 
·         most of the trucks/vans, beginning from EURO4
·         most of the diesel passengers cars with diesel engines, beginig from EURO 5  (Audi, BMW, Mercedes-Benz)
·         big new ships
·         trains
·         heating plants
·         construction machinery
