DEF Storage Heaters

Powerblanket DEF fluid heaters are temperature specific for Diesel Exhaust Fluid, and protect from freezing and maintain optimal temperatures. Diesel Exhaust Fluid (DEF) is one of the key components used to meet emissions regulations for diesel engines. For DEF to work effectively, it should be stored in a cool, dry, well-ventilated area. The ideal storage temperature for DEF is between 15ºF and 77ºF (-9ºC and 25ºC). In colder temperatures, it’s crucial to find an effective storage and heating solution for DEF. Powerblanket’s patented DEF tank heater takes the hassle out of DEF storage heating. Powerblanket DEF storage tanks save you time, money, and energy.

This heating solution for DEF prevents overheating and provides efficient freeze protection by enclosing the entire tote system and features a top flap for easy access. Built with a rugged vinyl shell that is safe to use in temperatures as low as -20ºF, you can be sure that Powerblanket products will keep your DEF storage containers warm when temperatures drop well below freezing.
