Blue Sky DEF​ 

Blue Sky manufactures diesel exhaust fluid to the highest standards meeting ISO 22241 and API specifications. A synthetically produced 32.5% urea solution which reduces the emission of poisonous nitrogen monoxides produced by diesel engines. The solution acts as a reducing agent for SCR systems.BlueSky reduces the NOx components of the exhaust gas to nitrogen, water and carbon dioxide, which are components of air. We ensure our BlueSky is of the highest quality solution for the exhaust gas after-treatment and can guarantee the faultless operation of the catalytic converter in reducing NOx emissions.



The Peak

Blue DEF​

BlueDEF Diesel Exhaust Fluid is a non-toxic solution engineered to help diesel-powered vehicles reduce emissions and improve fuel economy.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. 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. 

Products available in a 2.5 gallon case, 5 gallon pail, 55 gallon drum, or bulk.
