FAQ's
1) What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid or DEF is a high purity chemical solution containing 32.5% urea mixed with high purity water.
2) What is urea?
Urea is the active ingredient of Diesel Exhaust Fluid. Urea is created from synthetic ammonia and carbon dioxide when subjected to high heat and pressure and can be produced as a liquid or solid. Synthetic urea is used mainly in fertilizers but is used in plastics, animal feed, cleaning agents, and pharmaceutical applications.
3) What would I use Diesel Exhaust Fluid for?
Diesel engines are required to meet stringent emissions requirements in 2010. Many diesel engine manufacturers have chosen a technology called Selective Catalytic Reduction (SCR) to meet these requirements. When added to the exhaust gases Diesel Exhaust Fluid reduces the NOx to the EPA required levels. If you purchase a car, truck, tractor or any diesel powered product with SCR technology it will require Diesel Exhaust Fluid.
4) Do I add this fluid to the diesel fuel?
No, vehicles manufactured with SCR technology are designed with a separate urea tank to hold Diesel Exhaust Fluid. The fluid is sprayed into the exhaust system.
5) Is Diesel Exhaust Fluid a hazardous material?
No, Diesel Exhaust Fluid is classified as a non-hazardous product.
6) How often will refueling of Diesel Exhaust Fluid be required?
The consumption rate of DEF is between 2-4% of the diesel fuel consumption. For example, for every 100 gallons of diesel fuel consumed, between 2 and 4 gallons of Diesel Exhaust Fluid will be automatically injected into the exhaust system. A typical diesel truck could go about 300 miles on one gallon of Diesel Exhaust Fluid. The refueling interval will depend on the size of tank you have.
7) Does Diesel Exhaust Fluid have a shelf life?
Yes. The shelf life will depend on the temperature at which product is stored, however product older than one year is not recommended to be used.
8) Is this product affected by temperature?
Yes, Diesel Exhaust Fluid will begin to crystallize at 12°F. It can also lose its potency if stored for prolonged periods over 86°F. Brenntag can assist you in developing storage solutions to ensure these conditions are avoided.
9) What about freezing on the vehicle?
Diesel equipment has heated tanks and supply lines that are designed to freeze and thaw with no performance issues.
10) Will Diesel Exhaust Fluid be harmed if it freezes and then thaws?
No, the urea and water will not separate or lose its strength.
11) How much does Diesel Exhaust Fluid cost?
Cost can depend on a variety of factors. Please contact your local sales representative.
12) What advantages are there to Diesel Exhaust Fluid and SCR technology?
In addition to reducing NOx emissions, the use of DEF and SCR technology will typically result in improved fuel mileage for most vehicles. The amount of improvement will vary based on your equipment.
13) How do I obtain Diesel Exhaust Fluid?
If you are truck driver, DEF will be available at many of the locations where you buy diesel fuel. If you have a fleet, Brenntag can provide Diesel Exhaust Fluid in a variety of package and dispensing solutions that meet your needs.
14) How will Diesel Exhaust Fluid be stored and dispensed?
DEF is stored in dedicated containers and dispensed through dedicated dispensing units.
15) How is the quality of Diesel Exhaust Fluid insured?
DEF is manufactured to strict ISO 22241, AUS 32 and DIN 70070 standards. These standards ensure proper manufacturing, testing and handling procedures. Diesel Exhaust Fluid should only be purchased from companies that provide proof that they follow these standards.
