In 2010, the Envrionmental Protection Agency, OEM's and many trucking fleets have committed themselves to a cleaner environment by reducing NOX emissions. To reduce NOX emissions, most new trucks will be equipped with a Selective Catalytic Reduction (SCR) system. The SCR technology requires the use of diesel exhaust fluid (DEF).

Frequently Asked Questions

What Is BlueDEF?

BlueDEF Diesel Exhaust Fluid is the mixture of high purity synthetic urea and and deionized water that is used in Selective Catalytic Reduction (SCR) systems on diesel engines. BlueDEF 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 hydrogen and water.

How It Works

BlueDEF is carried onboard SCR-equipped vehicles in specially designed tanks and is dosed into the SCR system at a rate equivalent to 2-5% of diesel consumption. This low dosing rate ensures long refill periods, and the use of BlueDEF helps improve fuel economy allowing fleets to realize a reduction in overall operating costs.

Committed To Quality

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 22241-1 is in place to insure fluid quality. BlueDEF is manufactured in accordance to these strict standards giving you the peace of mind you need using it in your SCR system.

Storage

Storage temperature between 40° F and 80° F is recommended to maintain shelf life. Storage temperature 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.

How Much BlueDEF Will I Need?

BlueDEF is consumed at a rate of approximately 2-5% by volume to diesel consumption.
