![]() ![]() SCR process allows engines to operate at maximum efficiency, increasing fuel economy, and lowering costs. SCR is the leading technology being used to meet 2010 emission regulations that uses a urea based DEF and a catalytic converter to significantly reduce nitrogen oxides (NOx) emissions. OEMs and fleets equipped with Selective Catalytic Reduction (SCR) technology have seen fuel efficiencies ranging from 4% to 11%. If the stored temperature does not exceed over 75☏ for an extended period of time, DEF’s expected shelf life is approximately two years. If stored between 10☏ – 90☏, the expected shelf life is one year. DEF will degrade as time passes due to temperature and exposure to light. The shelf life of DEF is calculated on atmosphere storage conditions. DEF is consumed at roughly 3% of diesel fuel consumption, so for every 100 gallons of diesel, 3 gallons of DEF are required.ĭEF’s Shelf Life (Defined by ISO 22241-3) DEF is contained in a separate tank a user must never fill a diesel fuel tank with DEF. It is not explosive, flammable, toxic or subject to any hazardous product regulations. A clear liquid similar in appearance to water, DEF is safe to handle by humans, pets and the environment. The market for Diesel Exhaust Fluid (DEF) is a result of the emission requirements enforced by the EPA to meet the Clean Air Act specifications.ĭiesel Exhaust Fluid (DEF) is a high purity solution of urea in demineralized water (32.5%) which meets the automotive industry specifications defined by ISO 22241. Our portable DEF packages transport easily for refills in-shop, in-field and on-the-road.
