Powerblanket’s 330-gallon DEF storage heaters provide a range of heating solutions for warming and storing diesel exhaust fluid. These diesel exhaust fluid heaters operate at 120 volts and can deliver up to 1440 watts of heating power with an internal preset thermostat. Our patented design eliminates hot and cold spots by applying uniform full-coverage heat across the entire surface of the container, allowing users to keep DEF at the proper viscosity while remaining at specified thermal levels.

330-gallon DEF storage heaters come in two different thermal rating classes: 
  • Powerblanket - designed for any definitive heating applications, surrounded by a rugged vinyl shell, safe to use in temperatures as low as -20 F
  • Powerblanket Xtreme - designed for harsh climates, safe to use in temperatures as low as -40 F

All of our 330-gallon DEF heaters come as an insulated full-wrap design with cinch straps to secure a tight fit. They’re also water-resistant and can be used on poly and steel drums. All Powerblanket products are ETL certified to UL, CSA, and CE safety standards.
