DEF (AdBlue
®
)
•
Use the AdBlue
®
indicated at DIN 70070.
•
DEF (AdBlue
®
) is a harmless, colorless and odorless
liquid.
•
The freezing point of DEF is -11°C (12.2°F). Because the
volume of DEF (AdBlue
®
) may expand about 9% when it is
frozen, it's recommended to leave 10% of the total volume
of the tank empty after filling.
•
DEF (AdBlue
®
) may smell a foul odor if the temperatures of
the DEF (AdBlue
®
) is high.
•
Doosan recommends that temperature of the DEF
(AdBlue
®
) is between 4°C (39°F) to 60°C (140°F).
•
If the temperature rises about 60°C (140°F), the DEF
(AdBlue
®
) concentration might be high because of the
evaporation.
•
In the worst case, the circulation line of DEF (AdBlue
®
)
might be clogged by the DEF (AdBlue
®
) crystallization.
Non-permitted Container Materials for Storing DEF (AdBlue
®
)
Materials forming compounds because of reaction with ammonia, which may negatively interfere with the
SCR system: carbon steels, zinc coated carbon steels, mild iron
Non ferrous metals and alloys (copper, copper alloys, zinc, lead)
Solders containing lead, silver, zinc or copper
Aluminium, aluminium alloys
Magnesium, magnesium alloys
Plastics or metals coated with nickel
