This is the easiest to use, most cost effective drum heater we have ever offered! Simply wrap the amazingly thin band around the drum, attach the spring fastener, plug it in (110 volt) and set the attached thermostat. Thermostat adjusts from 50°F to 400° F (10° C - 204.4° C). The heavy-duty 4" (10.16 cm) wide heater has nickel-iron heating elements insulated with fiberglass and laminated between two layers of silicone rubber-impregnated fiberglass cloth with dense grounding grids. Fits 55 gallon (208.14 l) drum, 6' (1.82 m) power cord, moisture resistant, chemical resistant, spring closure expands 3" (7.62 cm). 1200 watts. Liquid must be at least 4" (10.16 cm) above band.
TIP: For speed heating, use 2 heaters, place a piece of styrofoam under the drum and cover with a styrofoam box.
