PTC element 12mm

PTC element 12 mm

This element automatically adjusts its power consumption until it reaches a pre-set temperature (Curie temperature). Thanks to its self-regulating properties, the same element can be used both for air- and water heating without any risk of overheating.

We have a standard range of PTC 12 mm as well as custom made products.
