What is AdBlue?

AdBlue is a high quality urea solution that is easy to use

AdBlue is the registered trademark for AUS32, or Aqueous Urea Solution 32.5% that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of oxides of nitrogen from the exhaust of UK diesel vehicles. AdBlue is a 32.5% solution of high-purity urea in de-mineralized water that is clear, non-toxic and safe to handle. It is non explosive, non flammable nor harmful to the environment. AdBlue is classified under the minimum risk category of transportable fluids. It is not a fuel, nor a fuel additive and needs to be used in a dedicated tank in your heavy-duty vehicle. It is replenished in a similar way to refuelling diesel. Should you spill AdBlue on your hands, simply wash it off with water.

AdBlue is now found on forecourts of UK AdBlue retail stations and at UK suppliers of fuel and other spare parts for UK heavy-duty vehicles.

How much AdBlue do I need?

Average consumption of AdBlue in UK vehicles is generally 5% of diesel use, so you will need to tank much less for AdBlue then you do for diesel. You will use about 5 liters of AdBlue to every 100 liters of diesel.

How should I store AdBlue in the UK?

AdBlue can be stored for 1 year if this is done in a correct manner ie away from direct sunlight. It needs to be protected from too warm or too cold temperatures. Its freezing point is at -11 degrees Celsius. When it thaws, the product will retain its initial quality. It should be stored in a sealed package and in a well ventilated storage area.

Why should I choose SCR with AdBlue over other technologies?

AdBlue combined with SCR offers you a fuel efficient solution, with lower CO2 emissions then competitive solutions. All major European and North American truck manufacturers currently offer SCR equipped models. The future Euro VI emission standard is set to reinforce the demand for this technology in the united Kingdom.

Why does AdBlue quality matter?

Various actions can affect the quality of AdBlue. To prevent contamination, it is imperative that foreign matters do not come into contact with the solution. Using contaminated AdBlue can lead to expensive catalyst replacement costs. The AdBlue trademark is currently held by the German Association of the Automobile Industry (VDA), who ensure quality standards are maintained in accordance with ISO 22241 (ISO-22241-1, ISO-22241-2, ISO-22241-3) specifications. Ensure that you only buy a reagent for your heavy duty vehicles that bears the name AdBlue with the registered trademark (®) on the product label. Buying AdBlue from Air1 UK is a guarantee of the correct specification required for use with your SCR technology.
