Extend the shelf life of your diesel exhaust fluid (DEF) while storing it in cold places. Also called heat blankets, these heaters wrap around 330 gal. DEF totes to evenly warm the fluid inside. They’re insulated with foam, so they retain heat even in chilly environments. Designed for DEF totes with a built-in pump, these heaters have an extended frame to fit the pump housing and an opening for the pump equipment. Manually set the temperature with the digital keypad. A thermostat automatically turns these heaters on and off to maintain the set temperature. To prevent overheating, a resettable fuse opens if the temperature rises above the maximum heat output.

Secure these heaters with the included buckles and straps—no need for adhesive. They’re quick to unbuckle and remove once your tote is empty. Made of heavy duty vinyl, these heaters stand up to scuffs, water, and UV rays, so they last even outdoors. The vinyl is NFPA rated for flame retardance; however, you shouldn’t use these heaters near combustible gases or dust. A ground fault circuit interrupter (GFCI) is built in to their power cord to prevent electrical shocks.

Add an insulated top cover to stop heat from escaping through the top of your tote. The cover has a flap that folds down to insulate the opening for pump equipment.
