AdBlue® Solutions FAQs

1. What is AdBlue®?

AdBlue® is a diesel exhaust fluid composed of synthetic urea and deionised water. It is injected into the exhaust system of diesel vehicles to reduce harmful emissions and meet Euro 6 standards. AdBlue® is non-toxic and non-flammable but slightly corrosive, so it should be stored in rust-proof containers away from direct sunlight.

2. How does AdBlue® reduce emissions?

AdBlue® is used in selective catalytic reduction (SCR) systems. When injected into the exhaust, it vapourises and triggers a chemical reaction that converts nitrogen oxides (NOx) into nitrogen, water and a small amount of carbon dioxide. This process helps reduce air pollution and supports environmental targets.

3. What happens if a vehicle runs out of AdBlue®?

If the AdBlue® tank is empty, the vehicle will continue to run until the engine is switched off. A dashboard warning light will appear when the range is around 1,000 miles and will flash at regular intervals. If ignored, the vehicle will not restart until the tank is refilled. Engine damage is unlikely, but performance may be temporarily impaired.

4. Is AdBlue® required for all diesel vehicles?

AdBlue® is legally required for most heavy goods vehicles (HGVs), vans and cars built from 2015 onwards that use diesel fuel. It is essential for meeting Euro 6 emission standards and avoiding penalties for non-compliance.

5. How should AdBlue® be stored?

AdBlue® should be stored in stainless steel or corrosion-resistant bunded tanks, ideally above ground. Bunded tanks have a secondary containment layer to prevent leaks. The fluid must be kept free from contaminants to protect the SCR system and maintain product quality.

6. What should be done in the event of an AdBlue® spill?

Spills should be cleaned promptly using water and absorbent materials to prevent crystallisation. Although AdBlue® is not hazardous, gloves are recommended during clean-up to avoid skin irritation. It should not be poured down drains due to its ammonia content.

7. What AdBlue® solutions does TSG UK offer?

TSG UK supplies, installs and maintains a wide range of AdBlue® dispensers and storage solutions for both fuel retail stations and commercial fleets. Options include plastic intermediate bulk containers (IBCs) and integrated steel tanks with twin compartments for diesel and AdBlue®.

8. Are TSG’s AdBlue® dispensers compliant with regulations?

Yes. All TSG AdBlue® dispensing solutions comply with ISO 22241 standards. This ensures compatibility with SCR systems and protects against corrosion and contamination.

9. What are the features of TSG’s AdBlue® dispensers?

TSG supplies Tokheim and Wayne AdBlue® dispensers, which feature corrosion-resistant components and advanced meter technology for certified accuracy. These dispensers are known for their reliability, long service life and minimal maintenance requirements.

10. What is the AdBlue® Combo dispenser?

The Quantium ML FHR and Helix 6000 II AdBlue® Combo integrates petrol, diesel and AdBlue® dispensing in one unit. It supports dual transactions and features a user-friendly display for fast, convenient fuelling.

11. Does TSG offer servicing and repairs for AdBlue® equipment?

Yes. TSG UK provides expert servicing and repairs for AdBlue® tanks and pumps, including transfer pump issues, motor replacements, electrical faults, damaged hoses, faulty meters and sensor repairs. All services are carried out by engineers with specialist AdBlue® expertise.

12. How does AdBlue® support sustainability goals?

AdBlue® helps reduce NOx emissions from diesel engines, contributing to cleaner air and supporting climate change targets. While alternative fuels such as electricity, gas and hydrogen are emerging, diesel will remain essential for heavy vehicles in the near future, making AdBlue® a vital part of sustainable fleet operations.

13. Can TSG support the transition to new energies?

Yes. TSG UK helps businesses move to greener fuels, including electricity, gas and hydrogen. At the same time, it continues to support existing diesel infrastructure by supplying, installing and maintaining AdBlue® systems, ensuring fleets remain compliant and operational throughout the energy transition.
