An adjustable thermostat senses the container’s surface temperature to automatically control heat output. These heat sheets permanently adhere to container surfaces to warm contents without direct contact.

Since the thermostat only responds to the container’s surface temperature, the temperature of its contents may be lower. The first time you heat material, monitor its temperature with a thermometer (not included) and record the thermostat setting so you can consistently reach the same temperature in the future.

Adhesive-back sheets have a pressure-sensitive adhesive.

For gentle warming, choose sheets with a watt density of 2.5 watts per square inch. Sheets with a watt density of 5 watts per square inch are good for general purpose heating. For rapid warm-up and high-temperature applications, choose sheets with a watt density of 10 watts per square inch.

Note: Do not cut, crease, or overlap these sheets—this will damage the heating element. Use a roller during installation to remove air pockets and ensure direct surface contact. Once sheets have been applied to a surface, they cannot be removed and reused.

Less than 0.015″ thick and highly conformable, these heat sheets warm components in tight spaces within complex designs. Stick them to surfaces with their adhesive back. You need a temperature switch or controller (not included) to regulate their heat output. Made of polyimide, these sheets emit minimal gas and won’t leave an oil residue, which means you can use them in vacuum systems.

Sheets with a watt density of 5 watts per square inch are good for general purpose heating. For rapid warm-up and high-temperature jobs, use sheets with a watt density of 10 watts per square inch. Choose sheets with a watt density of 20 watts per square inch for your highest-temperature applications, such as starting chemical reactions and altering the viscosity of liquids.

Note: Do not cut, crease, or overlap these sheets—this will damage the heating element. Use a roller during installation to remove air pockets and ensure direct surface contact. Once these sheets have been applied, they cannot be removed or reused.

For more durability than other adhesive-mount heaters, a thick layer of fiberglass-reinforced silicone rubber encases the heating element. These heaters permanently adhere to container surfaces to heat contents without direct contact. All require a temperature switch or controller (sold separately) to regulate heat output.

Also known as foil heaters, these bend around tank corners and edges without damaging the heating element. They permanently adhere to container surfaces to heat contents without direct contact. All have a pressure-sensitive adhesive back for easy installation. Heaters require a temperature switch or controller (sold separately) to regulate heat output.
