What is Diesel Exhaust Fluid?

Diesel exhaust fluid is one of the key elements of the Selective Catalytic Reduction (SCR) process used by most medium and heavy-duty engine builders to meet EPA 2010 regulations.

DEF is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. DEF is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, DEF helps convert NOx into nitrogen gas and water vapor—two harmless and natural components of the air we breathe.DEF is stable, colorless and odorless, and meets ISO Standards 22241 for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place to ensure optimum SCR performance.

Making sure you do not run out of DEF in a SCR equipped truck is simple—watch the Diesel Exhaust Fluid (DEF) guage, 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. The DEF tank fill opening is designed to accommodate a DEF fill nozzle to ensure only DEF is put into the tanks. A diesel fuel nozzle will not fit into the DEF tank opening.

Dispensing-Ensuring DEF Purity

Maintaining diesel exhaust fluid (DEF) purity and concentration is vital to the efficient and long-term operation of the SCR system. Product impurities can detrimentally affect the SCR system’s performance leading to premature catalyst deactivation and clogging of the system injector nozzles. Further more, maintaining the correct product concentration is critical to ensure the vehicle meets EPA 2010 emissions requirements.

Blue DEF is an API certified DEF that meets ISO Standard 22241 for purity and concentration, thereby ensuring optimum SCR performance.Furthermore, traditional lubricant equipment should not be used to dispense DEF fluid as it may be made of components, metals and seals that are not compatible with DEF and can be detrimental to product quality.DEF dispensing equipment was specifically designed to ensure full compatibility with DEF. All of our equipment has been field tested and proven in Europe, where SCR technology and the integral role DEF plays, has been used since 2006.
