PTC Heaters
frost protection and temperature stabilization in control cabinets

PTC heaters are used to protect electronics in control cabinets and enclosures against condensation, moisture and low temperatures.
Through self-regulating heat, PTC heaters contribute to stable operation and extended service life of components in industrial installations.

When are PTC heaters the right choice?

PTC heaters are the right choice when the enclosure is at risk of being exposed to low temperatures or condensation.

  • Frost protection in control cabinets at cold ambient temperatures
  • Condensation prevention which may cause corrosion or malfunctions
  • Self-regulating heating effect which reduces the risk of overheating
  • Energy-efficient solution for temperature stabilization

When might other solutions be more appropriate?

PTC heaters are not always the right solution. In some applications, different air conditioning is required.

  • High heat load that must be cooled down → cooling unit or filter fan is more suitable
  • Precise temperature control required → heater with control or thermostat solution
  • Very large enclosures where higher heating output is needed

FAQ - Frequently Asked Questions About PTC Heaters

PTC stands for Positive Temperature Coefficient and means that the heating effect automatically decreases as the temperature rises.

In many cases, the self-regulating function is sufficient, but a thermostat can be used for better control.

Yes, by raising the temperature in the enclosure, the risk of condensation is reduced.

PTC heaters are used in enclosures that are suitable for outdoor environments, not directly exposed.
