DEF 101
EPA Emission Requirements: In 2010 the Environmental Protection Agency, OEMs, and many trucking fleets committed themselves to a cleaner environment by reducing NOx emissions. To reduce NOx emissions, most new trucks are equipped with a Selective Catalytic Reduction (SCR) system. The SCR technology requires the use of Diesel Exhaust Fluid (DEF).
EPA Emission Requirements: The Challenge Facing Heavy Duty OEMs For 2010: Further Reduction Of Oxides Of Nitrogen (NOx) PM (g/hp-hr)
What is SCR Technology? SCR is an acronym for Selective Catalytic Reduction. It is a catalyst installed on the exhaust system of a diesel truck. It sprays DEF into the exhaust stream to mix with exhaust gases to convert to nitrogen and water.
OEM Position Exited The On-Road Market
The Benefit Of SCR Technology Less Heat Rejection Higher Engine NOx Levels + + Less Active Regenerations = * Compared To Same 2007 Engine
EPA Standards Are Not Limited To On-Road Applications 2010 On-Road Diesel Engines 2014 Off-Road Equipment 2014 Largest C2 Marine 2015 Locomotives 2016 C3 Ocean Going Vessels 2017 C1 Marine
EPA Standards For Off- Road Equipment: 2014 Opportunity: SCR Technology Is Widely Used Today In The Ag Market Why? Fuel Economy Improvement Of 10% Or More
What is Diesel Exhaust Fluid? Diesel Exhaust Fluid is the mixture of high purity synthetic automotive grade urea and deionized water that is used in Selective Catalytic Reduction (SCR) systems on diesel engines. 32.5% High Purity Synthetic Automotive Grade Urea 67.5% Deionized water Meets ISO-22241 Quality Standard
What is Diesel Exhaust Fluid? DEF is NOT a diesel additive. DEF is injected into the exhaust stream via a controlled dosing module where the water vaporizes leaving ammonia molecules free to travel into the catalytic converter where it reacts and neutralizes the NOx molecules, converting it to nitrogen and water.
What Is Urea? Urea Is A Nitrogen Compound With Many Commercial Uses: Fertilizer Animal Feed Supplement Production Of Adhesives And Resins SCR Systems Use A High Quality Urea Currently Used In SCR Systems In The Stationary Power Generation

The Difference Between Fertilizer And DEF QUALITY DEF
DEF Quality Standards SCR systems are sensitive to potential chemical impurities in the urea solution. Therefore, it is essential to maintain high standards of diesel exhaust fluid quality and ISO standard 22241 is in place to insure fluid quality. DEF is manufactured in accordance to these strict standards giving you the peace of mind you need using it in your SCR System.

DEF Characteristics Weighs 9.1 lbs per gallon Heavier than Petroleum Products Bulk Load = 5,000 gallons Will freeze below 12 F not affected by freeze / thaw Crystallization Creeping or Leaching
DEF Shelf Life Storage Temperature Between 40 F and 80 F is recommended to maintain shelf life. Above 12 F is recommended to avoid crystallization, which starts at 11 F. Prolonged storage above 86 F will cause hydrolysis to occur, with the consequent formation of ammonia and pressure rise, and will reduce shelf life.

3 Important Factors About Diesel Exhaust Fluid Quality Of DEF Is Critical To Vehicle Performance Informing Market About DEF Purity Is A Must It Needs To Be Stored And Handled Properly To Maintain The Quality
Impact Of Impurities In DEF when mixed with tap water or Ag Urea
Impact Of Aldehydes, Hard Water, And Insolubles Clogged DEF Injector Exhaust Pipe Clogged Catalyst
Just How Important Is Maintaining DEF Purity? One Teaspoon Of Salt Will Contaminate 5,000 Gallons Of DEF
Diesel Exhaust Fluid Handling Product integrity is critical. Stored in chemical equipment, not petroleum equipment. All wetted materials should be DEF compatible materials. Tanks Piping Hoses Nozzles Fittings Seals
