IIon IBC Totes as well as bulk storage and transfer systems. Western has brought together a wide range of products and services to provide a complete range of solutions for handling, storing and testing DEF fluid. Diesel Exhaust Fluid (DEF) is a mixture of 32.5% high purity Urea diluted in de-ionized water for use in Selective Catalytic Reduction (SCR) systems. This solution is stored aboard diesel engine vehicles and injected into the exhaust systems' Selective Catiytic Reduction (SCR) system, initiating a chemical reaction converting the pollutant, nitrous oxide (NOx) into harmless nitrogen and water. As of January 2010, diesel trucks have DEF storage tanks on board ranging in size from 16 to 30 gallons. Additionally, in 2012, "off road" equipment powered by diesel engines will be supplied with SCR systems requiring DEF. Then, in 2014, all diesel engines greater than 75HP will have SCR systems. Western offers a wide range of DEF handling equipment that conform to ISO 22241 specifications. Both, "open" and "closed" systems are offered and are available in electric, air or hand operated versions. These systems are designed to fit 55 gallon drums, 275 and 330 gallon IBC Totes as well as bulk storage and transfer systems.
DEF Should be stored In a room temperature environment and not inventoried for longer than 3 months for optium product quality.
