Process Heaters

Ultra-Thin Heat Sheets

Less than 0.015″ thick and highly conformable, these heat sheets warm components in tight spaces within complex designs.

Adhesive-Mount Heat Sheets

Stick these flexible heat sheets to container surfaces to warm contents without direct contact.

Adhesive-Mount Heat Sheets
with Temperature Control

An adjustable thermostat senses the container’s surface temperature to automatically control heat output.

Heavy Duty Adhesive-Mount Heat Sheets

For more durability than other adhesive-mount heaters, a thick layer of fiberglass-reinforced silicone rubber encases the heating element.

Ultra-Flexible Adhesive-Mount Heat Sheets

Also known as foil heaters, these bend around corners and edges without causing damage to the heating element.

Hazardous Location Adhesive-Mount Heat Sheets

FM approved, these heat sheets are safe for use in areas with infrequent exposure, such as from a spill or a ventilation system failure, to flammable gases, liquids, and dust.

Adjustable-Diameter Wrap-Around
Heaters for Pails and Drums

Nonstandard-size containers are no problem—use the hook-and-loop closure to adjust these heaters to fit a range of diameters.

Wrap-Around Heaters for Pails and Drums

Heaters are fiberglass-reinforced silicone rubber.

Heavy Duty Wrap-Around
Heaters for Pails and Drums

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.

Insulating Wrap-Around Heaters
for Pails, Drums, and Totes

Also known as heat blankets, these heaters completely surround containers for fast heating and increased heat retention in unheated and drafty areas.

Hazardous Location Insulating
Wrap-Around Heaters for Drums and Totes

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.

Insulating Wrap-Around Heaters for
Diesel Exhaust Fluid (DEF) Totes

Extend the shelf life of your diesel exhaust fluid (DEF) while storing it in cold places.

Insulating Wrap-Around Heaters for Gas Cylinders

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.

Insulating Wrap-Around Heaters for Propane Tanks

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.

Noncontact Wrap-Around
Heaters for Pails and Drums

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.

Constant-Wattage Heaters with Adjustable
Temperature Control for Pipes and Tubes

Turn the dial to control the percentage of time that these heaters cycle on, from 5% to 100%. Commonly used to thaw pipes, prevent valves from freezing, and heat beakers and flasks in labs, they're good for temporary and occasional use where rapid heating is required but precise temperature control is not.

Constant-Wattage Heaters with
Temperature Control for Pipes and Tubes

The thermostat automatically turns these heaters on when the temperature drops below 38° F and turns them off when the temperature reaches 45° F.

Ultra-Flexible Constant-Wattage
Heaters for Pipes and Tubes

Wrap the flexible heating element around small-diameter pipes and tubes or pack it into tight spaces.

High-Temperature Constant-Wattage
Heaters for Pipes and Tubes

Rated for a maximum heat output of 900° F, these heaters are often used for thawing frozen pipes and rapid spot heating.

Cut-to-Length Constant-Wattage
Heaters for Pipes and Tubes

With a cable that supplies the same wattage along the entire length, these heaters remain consistent regardless of the surrounding temperature. All require a temperature switch or controller to regulate heat output.

Self-Regulating Heaters for Pipes and Tubes

When the ambient temperature changes, these heaters automatically adjust the heat output along the length of their cable. Also known as self-regulating heat cable, they don’t require a separate temperature switch or controller.

Cut-to-Length Self-Regulating
Heaters for Pipes and Tubes

Also known as self-regulating heat cable, these heaters automatically adjust heat output at different points along their length to account for differences in environmental temperature.

Insulating Wrap-Around Heaters for Hose

Keep the liquid inside your hose from freezing, maintain your liquid’s viscosity, and prevent condensation in chilly environments.

Insulating Wrap-Around Heaters for Pipe

Keep liquid in your pipes from freezing, maintain a specific viscosity, and prevent condensation in cold areas.

Ultra-High Temperature Constant-Wattage
Heaters for Pipes and Tubes

For demanding applications such as hot-melt transfer pipes, these heaters have a maximum heat output of 1400° F.

Bend-and-Stay Heaters for
Ducts, Ovens, and Dryers

Form these flexible heaters into any shape to mount them through brackets, collars, and holes. They are also known as tubular heaters.

Battery Heaters

Keep your battery running at full power even when the temperature drops—these heaters warm batteries quickly without overheating them.

Bend-and-Stay Immersion Heaters with
Through-Wall Fittings for Chemical Solutions

Form these heaters into any shape and install them through container walls with the attached bulkhead fittings.

Heaters for Extrusion- and Injection-Molding Barrels

Heat resins, raw materials, and food with these heaters that fit around extrusion and injection-molding barrels.

Heaters for Nozzles

Often used with extrusion, injection, and blow-molding machinery, these heaters clamp around nozzles to keep material warm for consistent discharge.

Heated Storage Enclosures

Temporarily store and warm items—these enclosures heat the space inside them.

Cooling Wraps for Pails, Drums, and Totes

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.

Protective Equipment

Body Warming Sheets

Stick these sheets anywhere onto your clothing—they’ll radiate heat for up to 12 hours of warmth.

Hot and Cold Packs

Hand Warmers

Place these pads inside gloves and mitts for 10 hours of warmth.

Roof and Gutter Heat Cable

Before ice begins to form, install this constant-wattage heat cable on roofs and in gutters and downspouts to prevent damage caused by ice buildup.
