Offering simple troubleshooting solutions, low maintenance, and highly efficient heat transfer, Positive Temperature Coefficient (PTC) heaters — specialized resistors that vary resistance in accordance with their temperature — offer versatile, easy-to-use solutions for a range of industries.

Thermistor Technology

PTC heating for different industriesA resistor that changes resistance as a function of its temperature is also referred to as a thermistor.

Thermistors increase their resistance when temperature increases, thus resulting in a Positive Temperature Coefficient.

An NTC thermistor, meanwhile, decreases its resistance when temperature increases, resulting in a Negative Temperature Coefficient.

When crafted with very pure semiconducting ceramic, PTC heating discs, fins, and honeycombs make ideal solutions for specialty applications.

PTC heaters can quickly create enormous heat transfers in small spaces; in fact, these heaters can produce an instantaneous flow of heat that is 50% hotter than the flow created by more conventional oil or ceramic chip heaters.

Industries and Applications

With the ability to perform in extremely small spaces with superior heat transfer and safe, powerful, and energy-efficient operation, PTC heaters offer several benefits across a wide range of industries.

Food and Beverage

Versatile and compact, PTC heaters are especially useful in the food and beverage industry. Used for heating and temperature control in various appliances, including coffee hot plates, food warmers, and temperature-controlled containers, PTC heaters allow for consistency and reliability in a range of applications.


With superior dehumidification and anti-condensation properties, PTC heaters are ideal for food safety, food processing, and other high-moisture manufacturing processes. As moisture problems take on increasing importance in plant environments and USDA and federal requirements grow stricter, processors are looking to PTC heating technology to reduce humidity and resulting bacteria growth on food machinery and equipment.

Avoid issues encountered while using coil or conventional heaters including cracking or bursting.
