Positive temperature coefficient technology
BACKER: PTC ELEMENTS: PTC elements are used as heating sources in air heaters, drying units and compartment heaters for cars and trains. PTC elements consist of PTC thermistors and aluminum strips joined by brazing or gluing. The PTC element can be mounted in a frame of heat-resistant plastic or integrated a specific application.
GENERAL INFORMATION: "PTC ELEMENTS – POSITIVE TEMPERATURE COEFFICIENT: PTC elements offer many advantages such as quick and uniform heating of the element and no power variation despite the presence of air flow. They have a self-regulating function and a long life-time. There is no risk of overheating. PTC technology is also used in tubular and flexible elements."
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.
Element in stainless steel with vulkanized connection.
This PTC ceramic heater is designed for the heating of forced air and can be incorporated in a variety of heating appliances and systems.
The PTC technology offers many advantages compared to conventional resistance heaters. E.g. the self regulating temperature control and automatic temperature limiting effect offers increased safety and eliminates the need of extra thermal protection.
AIR: Our standard PTC-heaters are constructed for heating of forced air and can be built into several heating devices and systems.
The PTC technology offers many advantages compared to conven-
tional resistant heating elements, for instance the self-regulating
automatic temperature control gives an increased security and
eliminates the need of further thermal cut-off.
WATER: The element automatically adjusts its power consumption
until it reaches the pre-set desired temperature (curie
temp). Thanks to it’s self-regulating properties there is no
need for overheating protection and temperatureregulation
and the same element can be used both for air- and
water heating without any risk of overheating.
In addition to above standard range, unique PTC
elements can be produced, e.g. with nipple and cable.
