Flexible ceramic heaters

Robust but also thin and bendable


Flexible ceramic heaters are used for indirect heating of liquids or contact heating of solids. For these applications, the ceramic element is usually fixing to the object, assembled into sheet metal casing or mounted in a tube. Elektrotermija produces flexible ceramic heaters according to customer specifications. Resistance coils are placed in longitudinal holes on flat thin ceramic segments. This type of heater can be mounted as flat or as rounded, depending on the shape of the object. Heat is transferred by radiation, conduction and natural convection.
