AdBlue converts harmful NOx from your diesel vehicle exhaust into harmless nitrogen and steam, therefore considerably reducing the emissions of nitrogen oxides (NOx) that are a major source of atmospheric pollution and that lead to smog in urban centres. According to studies done by the World Health Association, NOx emissions are known to aggravate asthma.
Since 2005, legislation on diesel vehicles in Europe demanded a drastic reduction of NOx emissions. Vehicle manufacturers, and first and foremost those of large goods vehicles, had to re-think the exhaust systems on their vehicles. More and more diesel cars, tractors and other non-road vehicles are also now equipped with the SCR system in the exhaust.
"SCR" is the name of a post-combustion technology treatment for diesel vehicles, which allows them to reduce their harmful emissions of NOx (nitrogen oxides). SCR stands for Selective Catalytic Reduction. This technology requires the use of a reagent called AdBlue. Almost all of the main engine manufacturers use this technology to meet the requirements of new legislation on NOx (Nitrogen oxides) emissions.
The main components of the SCR system are the:
AdBlue is injected from the vehicle’s dedicated AdBlue storage tank into the exhaust pipe, which is in front of the SCR catalyst, but downstream of the engine. As it is heated in the exhaust, the AdBlue changes into ammonia (NH₃) and carbon dioxide (CO₂). When the nitrogen oxide (NOx) gases from the exhaust pipe react inside the catalyst with the ammonia, the harmful NOx molecules in the exhaust are converted into harmless nitrogen and water, which is released to the atmosphere as steam.
The SCR system is installed in your vehicle by the manufacturer and works automatically. You do not need to maintain or modify it. AdBlue is automatically injected into the exhaust depending on your vehicle engine’s load. As for adjusting the consumption, the level of AdBlue consumption is determined by the vehicle manufacturer.
To make sure that your SCR system works correctly, please make sure that you only use high quality AdBlue, such as that sold under the brand name Air1 by Yara. This will protect the investment you have made in your vehicle as a low quality reagent would not be pure enough and could be contaminated with impurities. This could cause damage to your catalyst and lead to very high repair costs, that the vehicle manufacturer will not cover.
Yara's AdBlue is marketed under the Air1 brand. Air1’s AdBlue is produced from a high purity urea solution. Urea is produced synthetically from ammonia and CO₂ (carbon dioxide), from which Air1’s AdBlue is extracted directly as “hot melt” urea, which is a different process to fertilizer grade urea. This AdBlue process is quality assured to ensure the correct, stringent specification is attained, ensuring the quality and purity of Yara’s Air1 AdBlue.

If you want to add AdBlue to the range of products you already offer your customers, do it by choosing the benchmark brand: Yara's Air1!
AdBlue is a solution of very pure urea. Yara is a leading producer of urea in the world, producing AdBlue in several plants across the world, and operating the world’s largest AdBlue plant in Sluiskil in the Netherlands. With Yara as a supplier, you can count on uninterrupted supply reliability, when and where you need it anywhere in the world.
Our AdBlue is extracted directly from the production of urea in a dedicated quality process, which guarantees purity. This is an extremely important point because not all AdBlue producers use this process which can affect quality. As the SCR catalyst is very sensitive to impurities, it is important for you to rely on a quality product through a supply chain dedicated to AdBlue. Demand the best quality for your customers.
Yara's Air1 brand has been on the market since the very beginning of the AdBlue market in 2005. We were one of the pioneers of this product, along with the OEMs of the vehicles using SCR technology. We know all the secrets and we'll let you take advantage of this unique expertise to get yourself started in this market. It's reassuring when you adopt new products to have an expert by your side.
Air1, Yara’s AdBlue brand is available through a network of authorised Air1 AdBlue distributors. You can buy AdBlue from retail stations or from resellers of fuel and other spare-parts for large goods vehicles. AdBlue can be delivered direct to your depot or garage in bulk from a road tanker to your bulk storage tank, or packaged in an IBC or drum.
Our Air1 distributors provide you with local service. You may find that your existing fuel and lubricant supplier might also be an authorised Air1 AdBlue supplier. Simply ask your current supplier for Air1 AdBlue from Yara.
