What is a PTC Air Heater?
A PTC air heater is an advanced heating device using ceramic-based PTC elements to provide heat. Ceramic-based PTC is different from traditional heaters which are typically made with metal coils that can over-heat. This technology self-regulates heating so the ceramic never gets dangerously hot, and when it reaches the desired heat, the energy consumption drops down.
How PTC Air Heaters Work Electric current is applied to the PTC ceramic heating element.
1. The PTC ceramic element heats up as the electric current passes.
2. As the temperature of the ceramic increases, the resistance of the PTC ceramic also increases. This decrease of electric current stabilizes the total heat output of the heating element.
3. The process of self-regulation and limit's the exposure in any overheated state. So no external thermostats are needed and will never over-heat.
