Process Heaters

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.

Ultra-Thin Heat Sheets

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

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.

Battery Heaters

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