Specially designed for service stations.


BlueTec, BlueHDi, BlueMotion ... the names headed with the word "blue" are increasingly proliferating among the diesel cars on the market. The cause is the entry into force of the Euro 6 Standard which limits the pollutant emissions allowed for engines, especially with regard to solid particles and NOx gases. Although there are mechanics that manage to comply with this standard without resorting to this type of gas cleaning systems, with the arrival of the Euro 6.2 standard, practically all diesel engines will require them.

Diesel engines generate less amount of pollutants and CO2 but, unfortunately, there are two emissions that are very dangerous and that must be reduced as much as possible: nitrogen oxides (NOx) and diesel particulate matter (PM) that generates the combustion of diesel.


However, NOx cannot be physically removed, so they require a chemical reaction to transform them once generated so that they do not go out into the atmosphere. To produce this chemical reaction, two elements are required: on the one hand, a catalyst that facilitates the process to take place and, on the other, a chemical compound that reacts with dangerous NOx and transforms them into other harmless gases . This additive is known commercially as AdBlue ® and is made up of a 32.5% solution of urea .


After combustion in modern engines, most of the NOx that is generated is NO and NO2 and, to prevent it from escaping into the atmosphere, a small chemical plant is introduced into the exhaust pipe of cars. This “automated laboratory” adds urea to the gases and causes them to react in the catalyst so that   nitrogen oxides are mainly transformed into nitrogen, water and CO2 . All three are safe and, although CO2 is a greenhouse gas, it is much less “active” than nitrogen oxides.


AdBlue® or AUS32, is a technical urea solution for automotive, diluted 32.5% in demineralized water, it is clear, it is not toxic and it is safe to handle. On the other hand, it can be corrosive to some metals, and the appropriate materials must be used for its transport and storage.


Initially, the technical specification was included in the DIN 70070 standard. In 2006, the ISO 22241 standard in force throughout the world arrived. In addition to the technical specifications of the product, ISO 22241 includes the methods of analysis of samples, as well as the requirements for the handling, transport and storage of AdBlue®.


For these reasons, our technical department has designed the City Series for urban service stations where space is a problem for the installation of a tank for AdBlue® that complies with the ISO 22241 standard; in order to meet the increased demand that will occur in this sector in the short term, as sales of diesel passenger cars with SCR will continue to increase.


Since the entry into force of the ITC / 360/2010 of February 2010, the use of pumps with metrological verification issued by the competent body for this purpose is obliged for their public sale.
