Nonstandard-size containers are no problem—use the hook-and-loop closure to adjust these heaters to fit a range of diameters. They wrap around containers to heat contents without direct contact. All require a temperature switch or controller (sold separately) to regulate heat output. Do not use with flammable materials or in hazardous areas.

Also known as heat blankets, these heaters completely surround containers for fast heating and increased heat retention in unheated and drafty areas. Do not use in hazardous areas.

Heaters with an adjustable thermostat automatically turn on when the temperature drops below your set temperature and off when it rises above your set temperature. Adjust the set temperature with the keypad.

Heaters without temperature control require a temperature switch or controller (sold separately) for regulating heat output. They have a resettable fuse that opens if the heater temperature rises above the maximum heat output to prevent overheating. Once you set them up, there’s no need to monitor these heaters because they have one consistent, safe temperature. There’s no risk of tampering with the temperature, which could damage containers and their contents. Add insulated expansion strips to make heaters for 22 1/2" dia. containers fit drums with a diameter up to 24.2". They’re also needed for these heaters to fit around drums with removable lids.

Add insulated top covers to reduce heat loss and speed up heating.

To prevent hot spots that can damage heat-sensitive materials such as adhesives, sealants, and food, these heaters warm the air around containers without touching them. They provide uniform heat to 80% of the container. An adjustable thermostat automatically turns the heater on when the temperature drops below your set temperature and off when it rises above your set temperature. Adjust the set temperature with the dial. Do not use these heaters with flammable materials or in hazardous areas.

Heaters for 5-gallon containers do not open; set containers in from the top.

Heaters for 55-gallon containers close around containers. They are mounted on casters.

Heat resins, raw materials, and food with these heaters that fit around extrusion and injection-molding barrels. All require a temperature switch or controller (sold separately) to regulate heat output.

Note: The heater must be sized to fit tightly around the barrel to prevent air gaps that lead to inefficient heating and premature failure.
