DEF PRODUCTS

DEF Products is a family run business. Ray Pedersen was the original owner who led the company from infancy until his passing in 2017. The company continues under the leadership of his wife, Sharon Stegmuller and General Manager Joe Servin and our 12 employees... Subsequently, DEF Products expanded its customer base to focus on all markets utilizing Selective Catalytic Reduction (SCR) technology, including trucking, off-road, airports, hospitals, mining operations, etc... In 2001 DEF Products and CDI began making Selective Catalytic Reduction (SCR), also know as DEF, for various diesel generating plants in Southern California and Catalina Island. Recently the EPA mandated that all new diesel trucks be fitted with a DEF system for controlling their emissions as of January 1, 2010. We manufacture DEF with a pure form of urea and pure reverse osmosis water from Siemens.
