What is BlueDEF Diesel Exhaust Fluid?


BlueDEF is stable, colorless, non-flammable, non-toxic and is classified as minimum risk for tranportation. BlueDEF conforms to the ISO-22241-1 specification for DEF, is API registered and meets or exceeds OEM specifications.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 in to the catalytic converter where it reacts and neutralizes the NOx molecules, converting it to nitrogen and water vapor - two harmless and natural components of the air we breathe.

BlueDEF® diesel exhaust fluid meets ISO 22241 standards and is certified by the American Petroleum Institute.


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. ISO standard 22241 was created to insure fluid quality of diesel exhaust fluid. BlueDEF® is manufactured in accordance to these strict standards giving you the peace of mind you need using it in your SCR system. With BlueDEF®, you get the highest quality diesel exhaust fluid you can buy, guaranteed!
