AdBlue ISO 22241 for Industry | Beta Pramesti Asia

AdBlue® is the registered trade name for AUS 32, a 32.5% urea solution in demineralized water used separately from diesel fuel in selective catalytic reduction (SCR) systems. Its quality must follow ISO 22241 and OEM requirements; misfuelling or contamination can damage SCR pumps, injectors, and catalysts.

PT Beta Pramesti Asia supplies industrial chemicals in Indonesia, including AdBlue procurement support for diesel fleets at mines and industrial facilities. A reliable proposal starts with OEM data, consumption history, storage size, site conditions, and the dispensing arrangement.

Composition of AdBlue

AdBlue is not a fuel or fuel additive. Its composition is:

• 32.5% urea meeting the AUS 32 quality specification
• 67.5% deionized water

This mixture is non-toxic and non-flammable.

VDA states that AdBlue contains 32.5% urea and 67.5% demineralized water; the AdBlue name applies to AUS 32 that conforms to ISO 22241 and its licensing conditions (VDA, AdBlue). ISO 22241-1:2019 defines AUS 32 quality characteristics for SCR systems, while ISO 22241-3:2017 covers handling, transport, and storage (ISO 22241-1; ISO 22241-3).

Document	Decision protected	Receiving evidence to request
ISO 22241-1	AUS 32 quality	Batch-traceable Certificate of Analysis
ISO 22241-2	Test methods	Laboratory method used for parameter verification
ISO 22241-3	Handling, transport, storage	Tank/hose cleanliness records and transfer procedure
ISO 22241-4	Refilling interface	Connection that prevents misfuelling and cross-contamination

Function and How it Works

AdBlue is used in SCR (Selective Catalytic Reduction) systems.
How it works:

1. AdBlue is sprayed into the hot exhaust gases of a diesel engine.

2. The heat of the exhaust gas decomposes urea into ammonia (NH₃).

3. Ammonia reacts with NOx inside the SCR catalyst and converts it into:

   • Nitrogen (N₂) and
   • Water vapor (H₂O),
     both of which are harmless to the environment.

AdBlue is not added to diesel fuel. VDA explains that it is held in a separate tank and reacts in the exhaust stream to form nitrogen and water. Because dosing is managed by the engine control unit, field consumption should not be fixed at one universal percentage. Use OEM data and historical litres of AdBlue per litre of diesel, engine hour, or kilometre to plan stock.

Role in Mining Industry

In the mining sector, AdBlue is used to:

• Reduce NOx emissions from large diesel machines (dump trucks, loaders, excavators, etc).
• Support compliance for equipment designed and certified with an SCR system, including selected Tier 4 Final or EU Stage V configurations.
• Protect aftertreatment function when fluid quality, filling, and maintenance follow OEM requirements.

The same quality discipline applies to SCR-equipped haul trucks, excavators, generators, and road vehicles. Buffer stock, however, must reflect active units, measured consumption, lead time, weather, site access, and the operating reserve.

Period requirement = active units × actual use per unit per day × operating days

For a planning example—not an OEM consumption claim—20 units recorded at 12 litres/day for 14 days require 3,360 litres. A site policy adding a 20% buffer produces a 4,032-litre receiving plan. Replace every assumption with fleet history and each model’s manual.

Things to Note in the Mine Area

• Protect AdBlue from excessive heat and direct sunlight; set the temperature and shelf-life limits from the supplier/OEM for the actual packaging system.
• It should not be contaminated with other materials (such as oil, fuel, or mine dust).
• Use tanks, pumps, hoses, nozzles, and sampling tools dedicated to AUS 32.
• AdBlue use must follow the equipment manufacturer’s SCR requirements.

ISO 22241-3 sets handling, transport, and storage practices intended to preserve AUS 32 quality until the fluid reaches the vehicle tank (ISO 22241-3). Quarantine a delivery if a seal is broken, batch documents conflict, the liquid is discoloured or visibly dirty, or misfuelling is suspected.

Risk point	Minimum control	Action if failed
Truck/IBC arrival	Match product, batch, seal, CoA, and volume	Quarantine; do not transfer
Storage tank	Clear label, dedicated connection, closed to dust/rain	Stop use and investigate contamination
Transfer	AUS 32-only hose/nozzle, capped when idle	Clean/replace components to supplier procedure
Equipment filling	Verify the AdBlue port; prevent diesel/oil contact	Do not start; follow the OEM misfuelling procedure
Inventory	FIFO/FEFO with batch and date records	Segregate expired or untraceable product

AdBlue storage audit checklist

1. Make AUS 32/AdBlue labels and the no-diesel warning visible at the tank and nozzle.
2. Match wetted materials, hoses, seals, and pumps to ISO 22241 and supplier approval.
3. Retain the CoA, batch, receipt date, supplier, volume, and transfer destination.
4. Inspect vents, caps, bunds, leaks, dust, rainwater, and evidence of shared hoses.
5. Reconcile use by unit against history; a sudden increase requires an SCR or leak check.
6. Sample only with a container and procedure that protect the fluid from contamination.

Conclusion

AdBlue for industrial fleets is a quality-controlled product, not agricultural urea dissolved on site. Procurement should verify ISO 22241 conformity, batch traceability, dispensing compatibility, and OEM requirements. See the wider industrial specialty chemical portfolio and mining chemical support.
