Also known as band heaters, these wrap around containers to warm contents without direct contact. 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. The spring-loaded clamp closure allows heaters to expand to fit around slightly larger container diameters. Do not use these heaters with flammable materials or in hazardous areas.

9 1/2" Overall Width—9 _1/2" wide heaters maximize surface area contact and heat distribution.

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.

Adjustable Thermostat—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.

Nonadjustable Thermostat—Heaters with a nonadjustable thermostat output a consistent heat and turn on and off intermittently to maintain that temperature. Since you can’t change their heat output, there’s no need to monitor them and no risk of tampering, which could damage containers and their contents.

Hazardous Location Thermally Insulating Wraparound Heaters for Drums and Totes


For 55 gal. Containers	For 275 and 330 gal. Containers

These ETL-listed heaters keep containers warm in areas where hazardous material is present. Also known as heat blankets, they surround drums and totes to heat them up quickly. They’re also insulated with foam or fiberglass to retain heat. They have a built-in thermostat that cycles on and off to keep contents at a set temperature. There's no need to monitor these heaters—since the temperature can’t be changed, there’s no risk of tampering.

Hazardous Location Rating—Hazardous location ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.

Wraparound Coolers


For 275 gal. Containers	For 5-, 15-, 30-, and 55-Gal. Containers

Cool the contents of your pail, drum, or tote from the outside. Since they cool from the outside, there's no risk of introducing contaminants to your material. These coolers are often used to stabilize solutions or keep liquids from evaporating. Connect them to a chiller or water source to circulate cold liquid around your container. Secure them with elastic straps. When they’re filled, these coolers conform to the surface of a container, eliminating air pockets to cool evenly. A layer of insulation locks in the cold and reduces condensation. As liquid flows out of these coolers, you can channel it back into your chiller or empty it into a drain.

You can also use these coolers to keep material warm—they circulate fluid up to 120° F. When using them at temperatures above 45° F, fill with water only.

Battery Heaters


Band Heater	Sheet Heater


NEMA 5-15	NEMA 1-15

Keep your battery running at full power even when the temperature drops—these heaters warm batteries quickly without overheating them. They fit most automotive and marine batteries. Made from oil- and acid-resistant materials, they stand up to the harsh conditions under the hood of your vehicle. Add a timer switch to automatically turn them on and off at a set time and day.

Band Heater—Band heaters are best if you want to move the heater from vehicle to vehicle or only need to heat your battery every now and then. They heat faster and more evenly than sheet heaters, and they’re simpler to install—just wrap them around your installed battery. However, you have to take them off before running your vehicle, so you can’t leave them on permanently.

Sheet Heater—Sheet heaters are best when you need to heat your battery frequently. They heat from underneath, so you’ll need to remove your battery to install them. Once installed, you can safely leave them inside your vehicle as it runs. Just make sure to secure the cord so it doesn’t get caught on any moving parts.

Thermally Insulating Wraparound Heaters for Gas Cylinders


	5-15

Strap these heaters around cylinders to keep gas flowing when the temperature drops. Also known as heat blankets, they heat cylinders from the outside, safely warming liquefied gas enough so that it can vaporize. They’re sized to fit industry-standard cylinders. Do not use these heaters in hazardous areas.

Adjustable Thermostat—The thermostat is adjustable, and it automatically turns the heater on or off to keep your cylinder at a consistent temperature.

LCD Display—Check the current temperature on the LCD display and use the keypad to make changes.

Cordura Nylon Fabric—Made with tough Cordura nylon fabric, these heaters resist mold and mildew, and they’re difficult to tear.

Acrylic Plastic—They’re also lined with acrylic plastic insulation to retain heat.

For Use Outdoors—Both the fabric and the NEMA 4X-rated controller are weather-resistant, so you can install these heaters on outdoor tanks.

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.

Thermally Insulating Wraparound Heaters for Propane Tanks


	5-15

Keep gas flowing even when the temperature drops—also known as heat blankets, these heaters wrap around propane tanks to safely warm liquefied gas so it can vaporize. These heaters are sized to fit industry-standard propane tanks. Quickly install and remove them using the buckles or latches. A GFCI is built into the power cord to prevent electrical shocks.

Nonadjustable Thermostat—Because you can’t adjust the thermostat, there’s no risk of accidentally changing the set temperature.

90° F Maximum Heat Output—Their built-in thermostat heats up to 90° F, then automatically adjusts the power output to keep your tank consistently warm.

Vinyl Plastic—Made of heavy duty vinyl plastic, these heaters stand up to scuffs, water, and UV rays, so they last even outdoors. The vinyl plastic is NFPA rated for flame retardance; however, you shouldn’t use these heaters near combustible gases or dust.

Foam—They’re insulated with foam, so they retain heat even in chilly environments.
