- Quick heating with self regulating function
PTC elements are used as heating sources in air heaters, drying units and compartment heaters for cars and trains.
PTC elements consist of PTC thermistors and aluminum strips joined by brazing or gluing. The PTC element can be mounted in a frame of heat-resistant plastic or integrated a specific application.
PTC elements provide a number of advantages, including fast and even heating of the element without variation in the power, even with high airflows. They are self-regulating and have a long working lifetime. There is no risk of overheating. PTC technology is also used in tubular elements and flexible elements. We now supply 12 mm PTC elements – click on Product examples for more information.
