DEF Roadsign

What is DEF?

Used throughout Europe since 2006, DEF is mandated by the EPA as part of the Clean Air Act, and meets Selective Catalytic Reduction (SCR) engine designs on most 2010 and newer diesel engine designs.

It improves fuel economy 3–5% and leads to more efficient combustion with near zero NOx emissions by converting NOx emissions into pure nitrogen and water. NOx or Nitrogen Oxides are exhaust elements that contribute to acid rain, smog, and greenhouse gas levels.

DEF Performance

DEF from PAPCO is API certified and meets ISO 22241 specifications. Diesel engine DEF consumption will be about 2–4% of its diesel fuel consumption. To maintain DEF quality it should be stored between 20°F and 85°F in a dry, well-ventilated area and out of direct sunlight.

On average, one gallon of DEF should yield around 300 miles of travel depending on driving conditions.

DEF Storage

DEF Handling and Storage

Specialized handling as well as dedicated storage and dispensing equipment are critical to maintaining DEF purity, functionality and integrity.

PAPCO specialists have the expertise to store, handle, transport and administer DEF for fleets in any weather condition. Our teams are constantly involved in ongoing education programs ensuring you always have access to the most up to date industry information in the business.

DEF Process

How DEF Works – The Selective Catalytic Reduction (SCR) Process

The use of DEF allows for a much more efficient combustion process with near zero Nitrogen Oxide (NOx). When injected into the exhaust stream, DEF converts NOx into water vapor and nitrogen – pure and natural components of the air we breathe – and passes them harmlessly through the tailpipe. It is a clean, uncomplicated process that is nontoxic, non-hazardous, nonpolluting and results in increased fuel economy as well.
