What are PTC Heaters?

PTC Convection Heating Improves Efficiency New PTC ceramic heating elements improve the efficiency of typical resistive heating elements used in applications where natural convection heaters are preferable over conventional forced-air heating. The PTC, Positive Temperature Coefficient, heating element is built into ext...

Four Selection Considerations for PTC Heaters Positive temperature coefficient heating elements have some unique properties that are taken into consideration when deciding which type to use for industrial applications. These are small scale heating applications for both industrial, commercial, and residential applications.           . Application Temperature & Controls Voltage & Watt Density Space & Safety How Does the Application Impact Design Considerations? We find PTC thermistor elements in almost every industry. They are primarily known as PTC heating elements or PTC ceramic heating elements utilized for creating heat. Used with industrial applications, these are small scale heating...

Cartridge, Immersion, Tubular, and Fin Heaters These terms can be confusing, and applications for each vary considerably. Round cartridge heaters, Square cartridge heaters, Cartridge immersion heaters, Flanged cartridge heater, Fin cartridge heater, Insertion heater, Rod heaters, Pencil heaters, Low density, and High density.

PTC Ceramic Heating Elements are Unique in Industrial Heating.

Industrial heating brings to mind huge furnaces, pouring hot lava-like metal, and long annealing ovens, but there is another subset of heating elements not talked about as often.

Windmills that provide clean energy for our home use them. 3D printing, an industry that's revolutionizing everything from engineering to healthcare, relies on them. Even outside electronic devices, such as ATMs, rely on PTC heaters to maintain an ideal working temperature.

You're probably wondering how these heaters can operate without getting too hot and damaging electrical components.
