Ideal location, optimal material: Tank systems for AdBlue®

Double-walled, overfill-proof, impermeable to liquids: The requirements a tank system for AdBlue® must meet depend on volume, location and environmental guidelines. We show you what you need to consider when purchasing an AdBlue® tank system and how to store the urea solution safely.

 

The right location

AdBlue® is not a particularly demanding substance. The chemical substance copes well with temperatures between -5°C and +20°C. However, you should avoid direct sunlight on your tank system, as the urea concentration of AdBlue® drops at temperatures above 30°C. Nor must the location be too cold either – at -11°C the urea solution freezes.

You can easily store AdBlue® containers outdoors. Remember to consider the precipitation water and adjust the retention volume accordingly if the site is not covered.

Your storage container is safe near kerbs, crash barriers, large field stones or similar, because collision protection is provided.

 

The optimal material

With tank systems made of stainless steel or approved plastic (polyethylene) you are on the safe side. Steel containers are unsuitable for storing AdBlue® because the urea will cause it to rust. If the tank system has a volume greater than 1,000 l, the tank must be double-walled or have a retention volume.

 

Observe the water law

Although AdBlue® is chemically harmless, it is slightly hazardous to water. Therefore, operators and owners of AdBlue® tank systems are obliged to comply with the provisions of water law. What you have to consider when filling the tank systems, whether splash protection walls are necessary and how you should handle contaminated water is laid down in the technical regulation TRsW 781. Important: It is essential to avoid AdBlue® getting into the light oil separator or the sewerage system. A liquid-impermeable filling surface is mandatory for storage and refuelling.

 

Retention volume – yes or no?

Basically, a retention volume is required when refuelling and storing AdBlue®. You can find exceptions in the regulatory service of the TÜV SÜD Industry Service GmbH. No retention volume is required, for example, if the filling hose cannot be driven over, the locking catch on the nozzle is removed and an immobiliser is used on the tank truck.
