What is AdBlue® / urea AUS32?

AdBlue® (also urea AUS32 or DEF – Diesel Exhaust Fluid) is an aqueous urea solution with 32.5% urea content, used in the SCR catalytic converters of diesel vehicles. It converts nitrogen oxides (NOx) into harmless nitrogen and water vapour. Since the Euro 6 standard, AdBlue® has been mandatory in almost all diesel cars, trucks and construction machinery – consumption is around 4–8% of diesel consumption.

Stationary vs. mobile tank systems

Stationary tank systems (2,500–9,000 L) are the economical solution for haulage operations, fleets and farms with their own AdBlue® demand – a lower purchase price by IBC or tanker, plus their own refuelling infrastructure. Mobile tank systems (200–1,000 L, with pump and meter, on wheels or as a transport cube) suit construction sites, changing locations and smaller fleets.

Kingspan BlueMaster – STANDARD & PRO

The Kingspan BlueMaster tanks are the best-selling stationary AdBlue® systems in Europe. BlueMaster STANDARD: a simple, rugged solution without electronics. BlueMaster PRO TitanAccess: with a full fuel management system, user identification, consumption recording and an optional climate package for operation in frost – even when AdBlue® freezes at –11°C.

Special requirements for AdBlue® systems

AdBlue® is corrosive to copper, brass and zinc – all system components (pumps, hoses, fittings, nozzles) must be made of stainless steel or AdBlue®-resistant plastic (HDPE, EPDM). Separate lines, fittings and draw-off points from fuel are mandatory. The Elafix-40 magnetic adapter for the vehicle tank prevents mix-ups.

Planning your AdBlue® supply – the right solution for your operation

📦

Drum, IBC or storage tank?

Drum/IBC (200–1,000 L): a flexible solution, no dedicated system needed – cost-effective for low demand. Downside: manual decanting, higher purchase price. Mobile system (200–1,000 L with pump): drum or IBC with an integrated pump and meter – for construction sites and changing locations. Stationary tank system (2,500–9,000 L): your own refuelling infrastructure, the lowest purchase price by tanker – economical from around 10 trucks or 2,000 L/month.

🏥

Why a climate package on the BlueMaster PRO?

AdBlue® freezes at –11°C – in frost the whole system can freeze and dispensing can fail. The optional climate package on the Kingspan BlueMaster PRO includes heating of the tank and the pump unit, so the system works reliably even in winter. For operations in regions with harsh winters, or for systems not housed in heated rooms, the climate package is indispensable.

📈

Fuel management – why does it matter?

The Kingspan BlueMaster PRO TitanAccess system records every refuelling event: driver ID, vehicle, quantity, timestamp. This prevents misuse, enables precise cost allocation per vehicle or department and provides reports for the fleet manager. It is indispensable above all for haulage operations with many drivers. Data is stored locally and can be exported.

🔌

Which pump for which use?

Hand pumps: for occasional draw-off from a drum – cheap, no power supply. 12V DC pumps: for mobile systems on vehicles or construction sites – connected to the vehicle battery. 230V AC pumps: for stationary applications in the workshop or at the fleet base. Flow rates of around 35–60 L/min are sufficient for most car/truck refuelling – trucks have AdBlue® tanks of 20–75 L.

Material compatibility – what may AdBlue® touch?

AdBlue® attacks the following materials: copper, brass, zinc, galvanised steel – all parts coming into contact with AdBlue® must be made of stainless steel (V2A/V4A), HDPE, PP or EPDM. That's why all AdBlue® fittings, nozzles and pumps are specially marked and not compatible with brass fuel fittings. ISO 22241 sets out the material requirements.

📝

Storage & shelf life of AdBlue®

AdBlue® has a shelf life of around 12–18 months when stored between 0°C and 30°C. At higher temperatures (above 30°C continuously) or in direct sunlight, urea breaks down faster. A maximum storage temperature of 35°C is recommended (ISO 22241). Storage tanks should therefore preferably be set up in covered, shaded areas. The climate package protects against frost, the right positioning against overheating.

Frequently asked questions about AdBlue® / urea AUS32

AdBlue® (also urea AUS32, DEF, SCR fluid) is a solution of 32.5% urea and 67.5% demineralised water. It is injected into the SCR catalytic converter (Selective Catalytic Reduction) of diesel vehicles and converts harmful nitrogen oxides (NOx) into harmless nitrogen (N₂) and water vapour (H₂O). Since the Euro 6 standard (cars from 2014, trucks from 2013), the SCR catalytic converter has been mandatory in almost all diesel vehicles. If the vehicle runs without AdBlue®, the engine control unit automatically reduces power or refuses to start the engine.
Consumption depends on the vehicle type and engine load. As reference values: cars and light commercial vehicles: around 0.5–1 litre of AdBlue® per 100 km (about 4–8% of diesel consumption). Trucks and heavy commercial vehicles: around 2–8 litres per 100 km – depending on the vehicle and load. Agricultural and construction machinery use correspondingly more depending on engine power. For a fleet of 20 trucks at 100,000 km/year, that works out to around 100,000–160,000 litres of AdBlue® per year – a stationary 9,000 L tank then has to be filled around 12–18 times a year.
Your own tank system pays off thanks to the lower purchase price in bulk containers. AdBlue® in an IBC (1,000 L) costs around 20–30% less than in canisters, and by tanker (5,000–10,000 L) a further 10–20% less. As a rule of thumb: from a consumption of around 2,000 litres per month (equivalent to around 10–15 trucks), a stationary system pays for itself within 1–2 years. Haulage operations with their own fleet, farms and municipal vehicle fleets are the typical buyers.
AdBlue® freezes at –11°C – considerably warmer than diesel (–25°C to –35°C). On cold winter days an unprotected outdoor system can freeze and fail. After freezing, AdBlue® can still be used once thawed – the quality does not suffer. Against frost: Kingspan BlueMaster PRO with climate package (tank heating and pump heating), set-up in heated rooms, covering the lines, or draining the pipework at night. On the vehicle side: modern vehicles have their own AdBlue® tank heating.
That is a serious defect: diesel in the AdBlue® tank destroys the SCR catalytic converter and the injection system – repair costs are typically €5,000–15,000. The other way round: AdBlue® in the diesel tank does less damage in small amounts, but can clog the fuel filter and cause corrosion. Against mix-ups: the Elaflex Elafix-40 magnetic adapter for the vehicle tank (the AdBlue® filler neck is magnetically secured), separate, colour-coded nozzles (blue for AdBlue®), and physical separation of the refuelling points. ISO 22241 requires mix-up prevention.
AdBlue® (urea AUS32) is not a hazardous substance within the meaning of the Hazardous Substances Ordinance and not a substance hazardous to water under the AwSV – unlike diesel and heating oil. Therefore no special official permits or WHG inspections are required for AdBlue® storage tanks. General set-up rules nevertheless apply: no direct sunlight above 35°C, no frost without a climate package, set-up on a level surface, accessibility for filling by tanker. For larger systems, it is advisable to consult the local building authority.
