Positive Temperature Coefficient ("PTC") heaters by Pelonis Technologies are specialized heating discs that enable superior heat transfer in a small space. Made from an advanced ceramic material, PTC heaters enable safe, powerful, and energy efficient heat transfer.

PTC heaters are available as a Fin element or in a Honeycomb form. By combining honeycomb PTC heaters with a PTC holder assembly, the heating elements can be configured to produce greater heat output. PTC heaters are used in a wide variety of applications across many industries.

Fin PTC Air Heaters, in particular, offer a range of unique benefits. Because they are self-regulating, there’s no risk of overheating, which allows for better conductivity, greater efficiency, and a longer life span while ensuring stable electronic response. Extremely versatile, these heaters are offered in various designs, including low air resistance models and high heating efficiency models; they can also be designed with either single or double insulation. Double insulation, in particular, allows for safe, efficient use underwater. Featuring fast thermal response time, low inrush current, and internal safety-fuse protection, as well as auto-cut-off to prevent abnormally high currents, Fin PTC Air Heaters are specifically designed for optimal safety. Available in a range of sizes based on customer needs, Fin PTC Air Heaters can be customized with outer frames, fuses, protective shields, and axial cooling fans.

Safe and energy-efficient Pelonis' specialty Honeycomb PTC heating disc is made from a revolutionary semiconductor ceramic material that has a very high Positive Temperature Coefficient (PTC). The application of power on the PTC, resistance is initially decreased and temperature increased. The disc has over 1,200 holes that heat the majority of the airflow across the surface area of the disc. This generates a massive heat transfer in a small space which produces an instantaneous flow of heat up to 50% hotter than ceramic chip or conventional coil heaters.

The honeycomb disc is very safe and functions below the combustion point of paper. Honeycomb holder assemblies hold 3, 4, or 5 disc configurations producing up to 2000 watts of heat output. Choose among the various Pelonis ready assemblies or customize according to specific application needs.
