What is AdBlue?
AdBlue is a non-toxic fuel additive which is required by many modern diesel vehicles, especially commercial vehicles such as lorries, tractors and buses. It is composed primarily of urea which is a safe and environmentally friendly chemical. By adding AdBlue to equipped vehicles, harmful environmental pollutants and gases are removed from the exhaust, helping to meet EU Euro 6 engine pollution standards.
Our AdBlue product is manufactured to the International Standard ISO
22241-1:2006 NOx Reduction Agent AUS32 – Part 1: Quality
How does it work?
AdBlue is consumed in the engine by a process called SCR (Selective Catalytic Reduction). Essentially the urea undergoes a chemical reaction with harmful Nitrous Oxide gases in the presence of a catalytic converter comprised of rare metals. At the end of this process the exhausted materials have been converted to Nitrogen, Water and small amounts of Carbon Dioxide which are much less harmful for people and the environment. With modern SCR technology claimed NOx reductions of up to 90% can be achieved. Combined with other technology such as particulate matter filters, SCR can help to achieve near zero emissions for diesel engines and is vital for commercial vehicles to achieve the European EURO 6 engine standards which are required by law.
Since AdBlue (also sometimes known as Diesel Exhaust Fluid or DEF) is consumed in the reduction reaction, it is important to ensure that the dosing tank is always adequately topped up, much like any other important fluid in the vehicle. If the tank runs dry there is a risk that the complex SCR equipment could be damaged and emissions could exceed legal limits.
Thankfully our AdBlue product, supplied in easy to use 5L jerrycans, makes it easy and cost-effective to maintain the DEF levels in your vehicle. For commercial operators, we can also supply larger volumes of up to 1000L to ensure that your fleet can stay on the road without interruption.
How much AdBlue will I need?
The average AdBlue consumption will be about 5% of diesel use. Therefore for motorway driving you will use about 1.5 litres per 100 km.
Is AdBlue affected by cold conditions?
No, our product can be used in all European conditions. If the temperature of AdBlue drops below -11°C in extremely cold weather, it does freeze. Some SCR trucks have heating systems, which ensures stable operation of the SCR system, even in the coldest weather.
However, AdBlue that is frozen is not damaged in any way and can
be used as soon as it has defrosted.
