Riscaldatori PTC

PTC elements are used as heating source in air heaters, drying units and compartment heaters for cars and trains.
PTC elements consist of PTC thermistors and aluminium strips put together by brazing or glueing. The PTC element can be mounted in a frame of heat resistant plastic or built-in in a specific application.


  • Rapid heating of the element
  • Self regulation function
  • Heating power controlled by the air flow
  • Uniform heating without any power variation
  • No risk for overheating
  • Long life time

Esempi di prodotti

Besides traditional PTC element Backer also produces tubular elements, where the PTC technology is used - please see below. We also keep a standard range of PTC element in plastic frame on stock for a fast delivery.

PTC Element 12 mm


The element automatically ajusts its power consumption until it reaches the pre-set desired temperature (curie temp). Thanks to its self-regulating properties, the same element can be used both for air- and water heating without any risk of over heating.
