Diesel Exhaust Fluid (DEF)
Diesel Exhaust Fluid (DEF) is a reactant
that’s key to the SCR process. It’s a
nontoxic, ultra-pure solution of urea and
ultra-pure water. Urea is a compound
of nitrogen that turns to ammonia when
heated. The fluid is non flammable,
and is not dangerous when handled as
recommended. However, it is highly
corrosive to certain metals, especially
copper and brass. Read the separate
section concerning the handling of DEF
solution.
Use only
Diesel Exhaust Fluid that is
clearly labeled as meeting ISO-22241
standards, and certified by the American
Petroleum Institute. The container must
display the API certification seal. Never
use agricultural or industrial grade
urea.
Use of fluids other than API certified
Diesel Exhaust Fluid will compromise
aftertreatment system performance,
increase emissions, and may impact your
product warranties.
Never dilute DEF
with water or any other fluid.
It is recommended that DEF not be stored
in extreme hot or cold conditions, or for
prolonged periods. Follow the instructions
for proper storage and handling as
indicated on the container or provided
with the purchase.
Note: Agriculture mixtures are not pure
enough for use in the SCR system and
impurities in the solution will comprise
the SCR system.
