PTC element | Standard range

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.
