PTC elements are used as heating source in air heaters, drying units and compartment heaters for cars and trains.
PTC elements consist of PTC thermistors and aluminium strips put together by brazing or glueing. The PTC element can be mounted in a frame of heat resistant plastic or built-in in a specific application.
Characteristics:
- Rapid heating of the element
- Self regulating function
- Heating power controlled by the air flow
- Uniform heating without any power variation
- No risk for overheating
- Long life time
