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. Those heaters for 56" high containers have an extended frame to fit pump housing, an opening for the pump equipment, and a cover with a flap to insulate the opening. Use them for epoxies, diesel exhaust fluid, water, chemicals, resins, rubber, and other materials with pumping applications.

Heaters without temperature control require a temperature switch or controller (sold separately) for regulating heat output. Some 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. Covers with a through-port access flap give you easy access and further minimize heat loss.

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.

For applications requiring high heat over long periods of time, these aluminized steel heaters warm up faster and are more durable than silicone rubber heaters. They wrap around containers to heat contents without direct contact. Heaters should be positioned at the base of the pail or drum. The spring-loaded clamp closure allows heaters to expand to fit around slightly larger container diameters. Heaters are not for use with flammable materials or in hazardous areas.

Heaters with three output settings have a dial to select low, medium, or high watt density.

Nonadjustable thermostat automatically turns the heater on when the temperature drops below the factory-set temperature and off when it rises above the factory-set temperature. The thermostat keeps the heater temperature at or below 165° F. Adjustable thermostats automatically turn 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.

Time-cycle controllers constantly cycle on and off to maintain your set temperature with less fluctuation than thermostats. Turn the dial to adjust the ratio of on to off time. Controllers require a thermometer (sold separately) for calibration and temperature monitoring.

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.
