2. What is AdBlue and why is it needed
AdBlue is a high-purity aqueous Urea solution containing a 32.5% solution of Urea in water. The quality of AdBlue is important and is defined in a DIN standard, DIN 70070
New legislation regarding exhaust emission limits have been set by the European Union. These new emission limits come into force in (EURO 4) and in 2008 (EURO 5). The limits are set out in several European Union Directives, including 88/77/EEC, 1999/96/EC and 2001/27/EC.
Selective Catalytic Reduction (SCR) and AdBlue has been selected by the European Vehicle Manufactures as the solution to reduce the emissions from Diesel engines.
SCR systems will be used on diesel powered heavy-duty vehicles over 3.5 tons to reduce the nitrogen oxide emissions (NOx). AdBlue usage amounts to approximately 3-4% of the fuel consumption on EURO 4 vehicles. A typical heavy-duty vehicle will consume approximately 3 tons of AdBlue each year.

3. How does SCR technology work
SCR is an after-treatment system which deals with emissions in the exhaust system. AdBlue is mixed with air and injected directly into a catalytic converter inside the exhaust system. A chemical reaction takes place which converts the NOx present in the exhaust into a harmless gas and water.

4. Projected Requirement for AdBlue in Europe
The requirement for AdBlue will increase steadily over the coming years. It is estimated that by 2010 the yearly demand for AdBlue will exceed 4 million tons per year and around 20,000 filling locations will exist in Europe.

5. Careful Handling is Required
Although AdBlue is considered non-hazardous it presents several challenges when it comes to storing and handling the chemical on a daily basis. AdBlue has the following specific properties
It quickly crystallises when exposed to air
It freezes at -11oC
It has a corrosive effect on some common metals
It should be protected for contamination
It should not be released freely into the environment
These properties require that AdBlue is handled with care. Any equipment that comes in contact with AdBlue must be made of suitable materials to prevent corrosion and contamination.
Dispensing systems must minimise contact with air to prevent crystallisation, provide protection from cold weather and prevent spillage. Conventional dispensing equipment is not suitable for handling AdBlue.

6. AdBlue Requires a Sealed Connection
To ensure AdBlue can be handled in a reliable and safe way, IDENTIC has developed a sealed dispensing system for refilling AdBlue on vehicles. This spill-free vehicle refilling system provides the following advantages
It prevents the risk of spillage reducing the risk of crystallisation and corrosion on the vehicle and at the filling point
It ensures only AdBlue can be filled in the vehicles AdBlue tank preventing the risk of incorrect filling which could permanently damage the vehicles SCR equipment or create a hazard
It protects the quality of AdBlue preventing the risk of contamination, ensuring the vehicle reaches the emission standards it was designed to achieve.

7. Spill-free Vehicle Refilling (SVR) for AdBlue

8. AdBlue SVR Nozzle and Tank Inlet Adaptor
IDENTIC has designed a spill-free nozzle specifically for use with AdBlue. The SVR Nozzle provides a sealed connection between the dispenser and the vehicles AdBlue tank.
Key Benefits
Only AdBlue can be filled in AdBlue tank
No spillage
No crystallisation
Protects SCR-system from contamination
Automatically filling to correct level

9. AdBlue SVR Tank Inlet Adaptor
A tank inlet adaptor is fitted inside the neck of the vehicles AdBlue tank. This allows the SVR Nozzle to be connected and ensures only AdBlue can be filled in the tank.
Key Benefits
Can be installed by the vehicle manufacturer or tank supplier
May be retrofitted by the vehicle operator
Adaptable for all types of vehicle tanks
Allows the tank inlet to be positioned at all angles
Built-in pressure and expansion control

10. Designs for Tank Inlet Adaptors
A range of tank inlet adaptors are being produced to suit different AdBlue tank designs

12. Refilling Using the SVR Nozzle for AdBlue

13. AdBlue SVR Nozzle in Use
Refilling Sequence – Connection (Step 1 of 3)
The operator connects the Nozzle to the vehicles AdBlue tank.

14. AdBlue SVR Nozzle in Use
Refilling Sequence – Filling (Step 2 of 3)
Pumping begins and the tank is filled to the correct level. The operator is free to stop the filling as any time or wait for the pump to stop automatically.
The VCM signals the pump when to start and stop

15. AdBlue SVR Nozzle in Use
Refilling Sequence – Disconnection (Step 3 of 3)
Filling is complete. The Nozzle is released and returned to the holster with no spillage.
