Diesel Exhaust Fluid (DEF) is one of the key elements of the Selective Catalytic Reduction (SCR) process used by most medium and heavy-duty engine builders to meet EPA 2010 regulations. BlueDEF(R) is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. BlueDEF(R) is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, BlueDEF(R) helps convert NOx into nitrogen gas and water vapor - two harmless and natural components of the air we breathe. BlueDEF(R) is stable, colorless and odorless, and meets ISO Standards 22241 for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place to ensure optimum SCR performance. Our patented closed liquid dispensing system provides everything you need to effectively dispense your BlueDEF(R). In order for BlueDEF(R) to work well product integrity is critical and our dispensing systems are the only way to maintain this quality. These reusable systems are also cost effective by providing a significant savings over single-use containers. BlueDEF(R) dispensing systems are available in configurations for fleet, retail and commercial applications. BlueDEF(R) is key to helping improve fuel economy by up to five percent while simultaneously reducing exhaust emissions.
