Diesel Exhaust Fluid
What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid (DEF) is installed on Diesel Engine Exhaust Systems, and found in diesel engines equipped with SCR systems to reduce nitrogen oxide emissions by converting nitrogen oxide into water vapor. Typically used in its standard form, DEF is a clear, colorless, non-toxic liquid. DEF is most commonly used in automotive, agriculture, and transportation industries. DEF is 32% Urea and 68% Deionized water.
What is the most effective storage solution for Diesel Exhaust Fluid?
Our experts recommend our Double Wall Polyethylene Tanks, as they provide the most protection against spills. Additionally, our experts may recommend specific accessories for DEF storage, such as proper venting, fittings, joints, manways, and secondary containment.

The Assmann Way
The Assmann difference is in the process. Assmann keeps quality first and failure far out of mind.
Uniform Wall Thickness
Uniform wall thickness provides better structural integrity compared to other tanks on the market. Because of its unified durability throughout, Assmann storage solutions are less susceptible to tears and spills.
Air Cooling
Air cooling eliminates a process related stress in rotomolding, where water cooling shocks the plastic and causes an abrupt stop to the curing process. Assmann is the only manufacturer who uses non-shielded molds with low temperature heat and gradual air cooling to ensure reliability that lasts.
Specific Gravity
Using a 1.5 rated tank gives additional wall thickness to help extend the lifespan of the storage tank. Assmann offers 1.5 rated storage tanks in either crosslink or linear polyethylene.
Venting
Under-venting is one of the most common causes for tank failure. When filling and draining tanks, it’s important to keep the tank from vacuum and pressure exposure. A vent two times the size of your largest inlet is required to avoid pressurization. Sometimes a larger vent is necessary when tanks are pneumatically filled. Assmann offers a variety of venting options in multiple sizes and configurations.
