DEF is used as a consumable in selective catalytic reduction (SCR) in order to lower NOx concentration in the diesel exhaust emissions from diesel engines.
By 2016 all newly manufactured over-the-road and off-road vehicles and equipment will be fitted with Seletive Catalytic Reduction (SCR) technology and use DEF tanks that must be regularly refilled to help reduce engine emissions.

DEF is a volatile product and requires specific handling. Listed below are a few tips on handling Diesel Exhaust Fluid.
- Use dedicated equipment for DEF dispensing and storing. Do not use funnels or bottles from other product. ISO standards have very strict limits on contamination, which limit the material that the fluid can contact. Per ISO standards, the suitable materials are Stainless Steel, Titanium, Hastelloys, and several plastics, so long as they are free from additives.
- Store DEF between something above 32 degrees and 86 degrees and not in direct sunlight. With proper storage your shelf life should be a solid 12 months.
- DEF Creep is the evaporation of DEF fluid that leaves a white powdery substance behind that can build up on the surfaces of your DEF containment and dispensing equipment. That substance is the crystallization of the urea in the DEF after the ionized water evaporates away. You should clean DEF Creep with water when possible for the crystals can cause the concentration of the DEF to be high causing equipment to shut down due to the sensors involved.
The table below shows our recommended onsite DEF storage based on the number of SCR equipped trucks you will be running out of the local location.
