Frequently Asked Questions

AdBlue® is a high purity aqueous urea solution used in selective catalytic reduction in diesel powered vehicles and machinery. The chemical formulation of AdBlue® is used to create a reaction with the noxious gases emitted by diesel engines to convert a percentage of those gases into harmless substances. Noxdown manufactures and supplies AdBlue® in bulk, IBCs, barrels and small packs.

If your vehicle requires AdBlue® it will have a separate tank, usually with a blue plastic cap labelled AdBlue®. There may also be a gauge in the cab to show how much AdBlue® the tank contains.

No. AdBlue® is injected into the exhaust and does not physically affect the engine in any way. It isn’t a fuel additive and should never be put directly into your diesel tank.

AdBlue® is a non-hazardous product and is safe to handle. The use of gloves is advised, however. For more information, please see our AdBlue® MSDS.

In general, equipment purchased from a reputable supplier should be compatible, so they should be able to answer any questions. Please note that AdBlue® is corrosive to some materials such as ferrous metals – mild steel for example. Non-ferrous metals like copper and aluminium can also be corroded, as well as alloys of these. Corrosion can lead to contamination of your AdBlue® and send it out of specification. If you suspect this has happened, we recommend that you seek advice.

Common compatible materials include stainless steel (304/L or 316/L), HDPE plastic and PP plastic. Most rubber hosing that is compatible with AdBlue® will be labelled as such. Plastics/rubbers that were coated with nickel or zinc in the manufacturing process are not compatible. These lists are not exhaustive as there are many more materials that are / are not compatible with AdBlue®, but those listed here are amongst the most common.

When stored in optimum conditions it is expected that your AdBlue® will have a safe shelf life of 18 months. Optimum conditions are defined as being out of direct sunlight, stored below 25 degrees Celsius, stored in a clean and dust free environment and stored away from any other chemicals that could potentially contaminate it. The product must also be stored in containers (including bulk tanks) made from compatible materials.

AUS40 is used in the marine industry and other heavy industry applications such as power plants. It is very similar to AdBlue but with a higher urea concentration of 40%. Noxdown supplies AUS40 in bulk, IBC and barrels.
