Old World Industries, a leading supplier of functional fluids, will distribute its BlueDEF™ brand of diesel exhaust fluid (DEF) to meet the demands of the North American commercial diesel vehicle industry beginning in 2010. The company's established supply network of 10 production locations and more than 4,500 distribution points will enable truck stops, fleet operators, dealerships and truck manufacturers to maintain DEF inventory. BlueDEF is a urea-based fluid that converts pollutant NOx into harmless nitrogen and water in selective catalytic reduction (SCR) emissions-control systems. It is required to help nearly all diesel-powered commercial vehicles meet new EPA standards taking effect in 2010.
