Product Description

Product Description

 

WHAT IS DIESEL EXHAUST FLUID (DEF)

Diesel Exhaust Fluid (DEF) is a non-toxic, high purity solution comprised of 32.5% urea and 67.5% de-ionized
water for specific use in Selective Catalytic Reduction (SCR) systems. Using this fluid in diesel-powered vehicles, such as
trucks, buses, and tractors, helps to reduce the amount of nitrogen oxides (NOx) emitted into the air by 90%. It is not a fuel additive and must be filled into the dedicated Diesel Exhaust Fluid tank on your diesel vehicle.

 

WHY DO I NEED DEF

 

Simply put, you need DEF to keep your trucks running. This is because many diesel engine manufacturers have chosen Selective Catalytic Reduction (SCR) technology to meet the 2010 EPA Emissions Standards. Diesel Exhaust Fluid is used in the SCR system for on-road diesel vehicles manufactured beginning in 2010. Without DEF, your diesel vehicles will not function. SCR and DEF are used to convert Nitrogen Oxide (NOx) into harmless Nitrogen and Water molecules. Nitrogen makes up about 78% of the air we breathe.

 

How Diesel Exhaust Fluid Works

 

When injected into the exhaust stream with a specialized dosing module, DEF vaporizes, leaving ammonium molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor-making for cleaner emissions. Making sure you do not run out of DEF in an SCR equipped truck is simple - watch the DEF gauge, which is part of the diesel fuel gauge, for when it is time to refill. DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The tanks range in size from 6 to 23 gallons depending on the truck's application.
.DEF is key to helping improve fuel economy by up to five percent while simultaneously reducing exhaust emissions.


 

Automotive Grade Urea

Automotive Grade Urea is a special, uncoated version of highest purity. It is a main component of urea solutions like Diesel Exhaust Fluid or AUS40/45 which are used within SCR-systems for the reason of NOx reduction. It is the only type of Urea that meets the ISO 22241 specification and the only suitable Urea for the production of DEF/AUS32/ARLA32 solutions. For meeting the ISO 22241 the Urea needs to be of highest purity/quality.
