DEF Quick Facts - Temperature Requirements
Q: Is Diesel Exhaust Fluid affected by temperature?
A: Yes, Diesel Exhaust Fluid will begin to crystallize at 12°F. It can also lose its potency if stored for prolonged periods over 86°F. If DEF begins to lose its potency, the system will simply dose the DEF at a higher rate than 2-4% to compensate for the decreased potency level. Brenntag can assist you in developing storage solutions to ensure these conditions are avoided.
