Diesel Exhaust Fluid Insulator

Diesel Exhaust Fluid (DEF) is injected into the exhaust system of modern diesel engines. Containing no chemical additives, DEF is used to break down nitrogen oxide into water vapor. Although beneficial to the environment, diesel exhaust fluid will freeze at 12°F. For gas stations and pumps in colder regions, insulated DEF tank covers are essential. Thankfully, our Bartelt team has the ideal gas pump cover solution for you and your application: our signature diesel exhaust fluid insulator! The DEFender™ was designed to insulate diesel pumps containing DEF to prevent the fluid from freezing. Our product has proven to be an effective and cost-efficient solution to the problems that arise when DEF is exposed to cold temperatures. Simply place one of our gas station pump covers over your DEF pumps to enjoy superior performance, efficiency, and safety.
