Diesel Exhaust Fluid
The Environmental Protection Agency, OEMs, 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).
What is NOx?
Oxides of Nitrogen (NOx) are exhaust elements that contribute to acid rain, smog, and greenhouse gas levels. Atlas oil Company is proud to be a part of the North American initiative to clean the environment and reduce NOx emissions. As a result, Atlas has become a major distributor of BlueDEF® diesel exhaust fluid.
What is BlueDEF®?
BlueDEF® diesel exhaust fluid is the mixture of high purity synthetic urea 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 nitrogen and water. BlueDEF® is not a fuel or fuel additive.
DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The DEF tank fill opening is designed to accommodate a DEF fill nozzle to ensure only DEF is put into the tank.
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® meets ISO standards and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place, which ensures optimum SCR performance. For more information on API certification, please visit apidef.org.
Storage temperature between 40F and 80F is recommended to maintain shelf life. Storage temperature above 12F is recommended to avoid crystallization, which starts at 11F. Prolonged storage above 86F will cause hydrolysis to occur, with the consequent formation of ammonia and pressure rise, and will reduce shelf life.
