Self-Regulating Cartridge Heating (PTC)

Resistenze_Cartuccia_Autoregolante (PTC)_2 Resistenze_Cartuccia_Autoregolante (PTC)_1


The self-regulating cartridge heaters contain a PTC (positive temperature coefficient) ceramic component.
The main feature of these components is self-regulation: they reach their maximum power with low temperatures and when the temperature increases, they reduce their consumption.
Self-regulation enables as well to avoid temperature
The PTC cartridge heater can be used fully immersed in
liquids or in free air.
