Diesel Exhaust Fluid (DEF)

What is Diesel Exhaust Fluid (DEF)?

Diesel Exhaust Fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. This system is called Selective Catalytic Reduction (SCR) and can be found on 2010 and later model year trucks and many diesel pickups and SUVs. DEF is not a fuel additive and never comes into contact with diesel. It is stored in a separate tank, typically with a blue filler cap.


Fuel Polishing

What is Fuel Polishing?

Fuel polishing is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and microbial contamination from such fuels as diesel, red diesel and biodiesel. This fuel contamination, also known as "fuel bugs" or "diesel bugs" build up over time in stored fuels if they aren't tested and treated on a regular basis.

Fuel polishing is a vital part of a Preventative Maintenance program for diesel fuel that is stored in a holding tank.  Diesel fuel in a holding tank starts to degrade in just six months from bacteria growth, dirt, water, and other contaminants.  Fuel polishing will decontaminate the diesel fuel so it can be used the most efficiently in your equipment.
 

Benefits of Fuel Polishing

  • Improved system performance
  • Environmental compliance
  • Reduced wet stacking in diesel engines
  • Increased equipment life and reliability
  • Less down time
