Our Sourcing Team, who has over 25 years of experience in the transportation industry, trusts PEAK Commercial & Industrial BlueDEF and they are in great company. In fact, BlueDEF is America’s #1 brand of Diesel Exhaust Fluid (DEF). We asked PEAK to answer four key DEF questions.
1. What Does Diesel Exhaust Fluid Do?
Diesel Exhaust Fluid is sprayed into the diesel exhaust streams of diesel engines to lower the concentration of nitrogen oxide, NOx, in emissions.
2. Why BlueDEF Diesel Exhaust Fluid?
Engineered for use in Selective Catalytic Reduction (SCR) systems on diesel engines, BlueDEF diesel exhaust fluid is comprised of a high-purity synthetic urea and deionized water mixture that improves emissions and fuel economy.
3. How Diesel Exhaust Fluid Works?
When injected into the exhaust stream with a specialized dosing module, BlueDEF’s water vaporizes, leaving ammonia molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor – making for cleaner emissions. To ensure SCR performance, Diesel Exhaust Fluids must adhere to the ISO 22241 Standards.
4. What is Diesel Exhaust Fluid Made Of?
DEF is made with 32.5% urea, (NH2)2CO, and 67.4% deionized water. DEF is non-toxic and safe to handle, but it can corrode some metals, so it must be stored and transported carefully.
