Product Brochure

Each shipment comes with a laboratory certification that it meets the ISO specification
and extraordinary care is taken in the chain of custody to the end consumer to ensure that
whether the DEF is in one, two-and-a-half gallon jugs, drums or 275 or 330 gallon totes it
is of the same guaranteed quality. This also applied to DEF that is delivered in bulk, with
dedicated tank trucks hauling only DEF making the deliveries.
BlueDEF refers to this as a closed liquid system and is one of its differentiators compared
to some competitors. Customers are also required to have closed systems that have a
valve coupling system that seals the container opening on drums and totes (IBCs) that
meets BlueDEF specs. This will prevent contaminants such as dirt, debris and bugs, from
entering the container.
BlueDEF is unique in its
careful handling of its DEF but
a customer should look for the
correct labeling. If shopping
on the spot market, there is no
guarantee that the DEF will be of
the same purity as the fluid that
is distributed in this closed liquid
system. There may be problems
with the water used to dissolve
the urea, or the urea may itself
be of inferior quality.
CONsequeNCes Of iNferiOr Def Or shOrt supply
The consumption of DEF is only around 2% to 3% of the volume of diesel fluid, so heavy
and medium trucks carry only around 25 gallons or less of the exhaust fluid on board.
More would only add weight to the system. But with such low rates of use, poor quality
DEF can lead to problems with the injection system that introduces the fluid into
the exhaust. If the DEF is off-spec and not cleaning the truck exhaust as it should, a
downstream NOx sensor will send a fault code and a warning to the driver. This will also
happen if the truck runs out of DEF because the driver didn’t top up the DEF tank when
filling the vehicle’s diesel fuel tanks.
