Fibrothal® prefabricated heating modules

Prefabricated heating modules with metallic heating elements and vacuum-formed ceramic fiber insulation for up to 1350°C (2460°F) element temperature.


The construction method of Fibrothal® heating modules ensures accurate positioning of the coils and eliminates the distortion or other problems connected to the conventional open coil elements in grooves or on tubes. Fibrothal® heating modules also provide major energy savings in several applications.

The low thermal mass and thermal conductivity of the ceramic fiber furnace linings mean that you can build industrial furnaces which, depending on the type and mode of operation, contribute significantly to energy saving, higher output and better availability.

In the electrically heated furnace, however, it is very expensive and time consuming to combine ceramic fibers, such as blankets or folding blocks, with electric heating elements. This has led to the product concept which we introduced to the market in 1978 under the trademark Fibrothal®.

Today the Fibrothal® trademark covers a family of products consisting of vacuum-formed ceramic fiber components, with or without electric heating elements.
