Urea 

DEFendal® Diesel Exhaust Fluid is comprised of two major components; urea and deionized water (DI). Urea is an organic compound with the chemical formula (NH2)2CO. Urea has common uses in fertilizer, agriculture, and the pharmaceutical industry. Urea is used at a 32.5% mixture with 67.5% DI water in DEFendal Diesel Exhaust Fluid in Selective Catalytic Reduction Systems (SCR). The fluid is used to reduce the NOx pollutants in exhaust gases from combustion from diesel, dual fuel, and lean-burn natural gas engines. In SCR systems, a water-based urea solution is injected into the exhaust system. The ammonia produced by the hydrolysis of urea reacts with the NOx emissions and is converted into nitrogen and water within the catalytic converter.

 Quick Facts! Urea Based DEFendal Diesel Exhaust Fluid is:

  • A stable fluid that will not separate, and is colorless
  • Not flammable
  • Not a pollutant
  • Not listed by any U.S. or Canadian transit authority as a hazardous material
  • Not impacted by freezing and subsequent defrosting. It does, however, freeze at 11°F. The heating and cooling system on board is used to thaw the fluid.
  • Will degrade in direct sunlight
  • May have a slight odor similar to ammonia
  • Weighs 9.10 lbs per gallon and is shipped Class 14 as an “Environmentally Friendly Fluid”
