PTC elements
Positive temperature coefficient technology
DESCRIPTION
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 offer many advantages such as quick and uniform heating and no power variation despite the presence of air flow. They have a self-regulating function and a long life-time. There is no risk of overheating. PTC technology is also used in tubular and flexible elements.
