The quality of AdBlue is important, and this is controlled by the DIN V 70070 standard.

Why do I need to use AdBlue?

AdBlue is used by an advanced pollution control technology installed in the exhaust system called Selective Catalytic Reduction or SCR. SCR systems work by reacting AdBlue with the harmful NOx gases in the exhaust to form harmless water and nitrogen. NOx is an abbreviation for nitrogen oxide gases, which are produced during the combustion process in diesel engines and are one of the main components of atmospheric pollution.

It is important to ensure that you always have an adequate supply of AdBlue in the tank. If a truck or bus with an SCR system is operated without AdBlue, then there is risk that the complex SCR equipment will be damaged, and the emissions will not meet legal requirements. The driver would also experience a loss of engine power until the vehicle is refilled with AdBlue.

What is Euro 4 and 5?

Euro 4 is a new standard in Europe that limits the amount of harmful pollutants from commercial vehicles, and was implemented in October 2006. Euro 5 is the next, more stringent standard and will be fully implemented by October 2009. In some countries, Great Britain Included there are tax incentives for investing in Euro 5 vehicles before the regulations enter effect.

What does AdBlue cost?

The cost of AdBlue varies depending on where and how you buy it. AdBlue is not taxed like diesel (although VAT applies), and normally costs about half of the price of diesel. In most driving conditions, the cost of AdBlue will be more than offset by savings on diesel fuel consumption. Please contact Keith Pennington in our parts department to discuss your requirements and storage ability (01942.230026).

How much AdBlue will I use?

As a rough rule, average AdBlue consumption will be about 5% of diesel use. Therefore for motorway driving you will use about 1.5 litres per 100 km.

What is AdBlue made from?

AdBlue is a made from a chemical called urea (sometimes called carbamide) dissolved in pure water. Urea is a synthetic product, generally manufactured from natural gas, and is used in chemical fertilizers, plastics, and cosmetics. AdBlue is not made from recycled agricultural products.

Is AdBlue affected by extreme weather conditions?

AdBlue can be used in all European conditions. If the temperature of AdBlue drops below -11°C in extremely cold weather, it freezes. Therefore AdBlue pumps in the Nordic countries and other cold areas are heated to resist winter problems. Some SCR trucks have heating systems, which ensures stable operation of the SCR system, even in the coldest weather.

AdBlue that is frozen is not damaged in any way, and can be used as soon as it has defrosted.

Where can I buy AdBlue?

You can buy AdBlue at filling stations and from dealers across Europe. FindAdBlue.com allows you to enter your location, or planned route, and find the most convenient filling stations selling AdBlue. FindAdBlue.com also provides you with information about the suppliers that can deliver AdBlue to your home depot.

Can I use a normal pump?

No, definitely not! Adblue is horrible stuff to dispense. It’s 67% water so rusts steel, oxidises aluminium and leeches brass. What’s worse it dries to form solid crystals.

So what do I do now ??

In co-operation with GreenChem suppliers of AdBlue we supply equipment developed equipment to dispense AdBlue safely and reliably. We can offer either a 1,000 ltr IBC pump set, floor standing cabinet pumps or smaller 18 and 10 ltr containers. The larger storage facilities use specialist pumps, meters, hoses, nozzles and fittings. The cabinet version can be connected to an IBC or a bulk storage tank.
