DIESEL EXHAUST FLUID
DEF
What is DEF?
DEF is the reactant necessary for the functionality of the SCR system. It is a carefully blended aqueous urea solution of 32.5% high purity urea and 67.5% deionized water.
How do I store DEF?
DEF should be stored in a cool, dry, well-ventilated area, out of direct sunlight. While the optimum storage temperature is up to 77 deg F (25 deg C), temporary exposure to higher temperatures has little to no impact on the quality of DEF.
5,500-gallon Bulk DEF trailer no job is too big or too small.
