What is AdBlue®: discovering the additive with special care of the environment

More and more often, we found it in the fuel tanks of diesel vehicles, both private and industrial transport: it is a small blue cap that is beside a black one, or yellow, larger-sized, traditionally dedicated to refuelling diesel.
Is the AdBlue® tank blue cap, the innovative additive that, introduce in our cars or in our tractors, allow to reduce the highly polluting emissions of exhaust gases, having a positive impact on the environment.
Since the introduction of Euro IV and Euro V regulations, up to the current Euro VI, diesel engines have been applied to the technology “Scr” (Selective catalytic reduction), an emission treatment system, that, by injection of a special substance after the combustion phase at hight temperature, adding it to the exhaust gases before they enter the catalyst, converts the fumes nitrogen oxides (“Nox”), dangerous for health, into substances such as nitrogen and water vapour, which on the other hand, are not dangerous, even reducing particulate matter.
This substance, whose international code is Aus32, is precisely AdBlue® (commercial name is held by Vda, Association of German car manufacturers; in the Usa is called “Def” and in Brazil “Arl32”), whose international code is Aus32.
Tecnically, is a solution with hight Urea purity at 32,5% demineralized water, present in an amount of 67,5%: this product is generated by special systems, which is colourless and generally odourless, complies with the characteristics indicated by European normative Iso 22241 as it is non-flammable and also non-toxic.
The AdBlue® consumption oscillates on average between 1% (for cars) and 5% (for commercial and industrial vehicles) of the diesel consumption, so you need a few AdBlue® litres every thousand kilometres. It is important that dedicated tanks, generally made to contain few litres teens of the substance, don’t run out of fuel, because in case of additive absence the engine will remain stationary until the essential topping up.
In the light of the spread AdBlue®, in the renewed context towards “green” issue, in recent years the AdBlue® roots has been growing, investing all the means of the last generations that are precisely equipped with the “Scr” system.
But where recover additive? The finding develops on various commercial channels, starting from the service areas, more and more often equipped with special dispensing pumps and from the resale spare parts auto, but also from a big supplier present at international level.
It is important to underline, for those who want to buy this additive, the important service offered by Emiliana Serbatoi.
The Italian company, always attentive to the environment respect, has been the first worldwide operators to launch a wide range of products dedicated to the AdBlue® storage and transport.
There are a lot of solution proposed, from handy Emilcaddy 55 and 110 litres until the polyethylene tanks of teens of thousand litres, passing through intermediate proposal such as Bluetank (from 3 thousand to 10 thousand litres, also in the certificate version), Giantank (3.300 litres) and transportable Hippotank (960 litres) and Carrytank (from 220 to 440 litri). In the Carrytank range stand out 400+50 and 900+100 combined tanks that join in a single product two tanks, one for (from 400 or 900) and one for Urea solution (from 50 or from 100) just to meet the needs of the market that, as mentioned above, demand the availability in parallel both Diesel and AdBlue® to power the means of the new generation.
Finally, in Emiliana Serbatoi offer there are also two products designed for the certified refuelling “Mid”, approved for commercial transactions of solution based on Urea: it is Emiltrolley Mid, the electric tank refuelling system for 60 or 200 litres drums and EmilBlue Station (from 1.500 to 6.000 litres).
