Our production also includes PTC medium density heating elements for applications that reach a maximum temperature of 220°C.

In the place of resistive wire, PTC cartridges have a ceramic semiconductor with positive temperature coefficient, separated from the sheath by a layer of compressed magnesium oxide.

This type of heater does not need overheating safety systems because as the temperature rises resistance increases, reducing power absorption.

PTC cartridges are used for secondary domestic heating (towel warmers), industrial/commercial refrigeration (for evaporating the water from defrosting refrigerated counters) or for anti-condensation on numerous applications.
