Avoid Cracks, Bursts, and Burns in PTC Heaters

Under certain airflow conditions, PTC (positive temperature coefficient) heating solutions may fail as a result of cracking, bursting, or even burning.

PTC Heater Burns These issues are commonly caused by poor airflow or poor, incomplete, or improper combustion: Dirty or otherwise obstructed vents can lead to poor airflow, which in turn overworks the furnace and causes premature damage, while subpar combustion causes burners to run longer and hotter in order to achieve the same amount of heating output.


Long periods of use can also cause failures; over time, the stress caused by normal expansion and contraction of a furnace as it turns on and off in its cycles can result in cracks.

Solutions for PTC Heater Cracks

Use of Fin PTC Air Heaters provides a simple solution for cracks, bursts, and burns; specifically developed to prevent typical issues encountered with coil or conventional heaters, these heaters are self-regulating, meaning they won’t overheat.

By eliminating the risk of overheating, these heaters offer greater operating efficiency, stable electronic response, and longer life expectancy.

Extremely versatile, Fin PTC Air Heaters can be used in a wide range of applications, including electric automotive vehicles, general dehumidification, and thermal retention, and are frequently found in electronic household appliances such as hand dryers, irons, laminating machines, air conditioners, and adhesive sealing machines.
