What is AdBlue?

AdBlue is a colourless, solution made up of urea and de-mineralised water. It is injected into the car’s exhaust stream to eliminate harmful NOx, reducing it into harmless nitrogen and oxygen.

What is ISO 22241?

This an international standard which specifies the quality characteristics of AdBlue, together with handling and storage requirements.

Are your AdBlue Tanks ISO 22241 compliant?

Yes. All AdBlue Tanks supplied by us, together with all wetted components are manufactured from AdBlue resistant materials, compliant with ISO 22241.

Do you recommend a Dry Break Coupling for bulk AdBlue deliveries?

Yes, we do. A Dry Break Coupling significantly reduces the risk of contamination during refuelling. Additionally, the use of a Dry Break Coupling all but eliminates the risk of cross contamination as a result of mis-delivery e.g. Diesel fuel being delivered to an AdBlue Tank. All Harlequin Bunded AdBlue Tanks are equipped with a Dry Break Fill Coupling as standard. 

Can I store AdBlue in a Diesel Tank?

No. AdBlue is a specialist chemical which requires specialist containment. Storing AdBlue solution in a tank which is not purpose designed or approved for the storage of AdBlue will result in product contamination. This will damage not only to the tank, but also any vehicles or equipment filled from it.

Should AdBlue Tanks be bunded?

Yes, all static AdBlue Storage Tanks and AdBlue Dispensers should be bunded, or afforded adequate secondary containment, to reduce the risk of spills. As an environmentally responsible supplier, all Bulk AdBlue Tanks we offer are fully bunded, to protect against the risk of pollution. There is no requirement however to bund Portable AdBlue Tanks, unless the tank is being used as a static storage tank, in which case it should be positioned within a suitably bunded area. 

What is the minimum delivery volume for a bulk AdBlue delivery?

Whilst the minimum order delivery for a bulk delivery of AdBlue has fallen significantly over the past decade, it does vary by supplier. We strongly recommend contacting your AdBlue supplier to determine minimum order volumes, before ordering any tank.

Are your portable AdBlue Tanks ADR compliant?

AdBlue Tanks are exempt from ADR requirements. AdBlue solution is not classified as a hazardous liquid.

How often should my AdBlue Tank be inspected?

All AdBlue Tanks should be inspected at least annually, by an independently accredited storage tank technician. Similarly, we recommend that all electrical connections should be inspected for electrical safety at least annually.

Is AdBlue flammable?

No.
