Moduthal® heating modules

Moduthal® heating modules

Prefabricated heating modules with metallic heating elements and non-electrically conductive, dense ceramic insulation for use at element temperatures up to 1350°C (2460°F).


The construction method of Moduthal® heating modules ensures accurate positioning of the coils and eliminates the distortion or other problems connected to the coventional open coil elements in grooves or on tubes.

A fibre-free version of Moduthal® heating modules is available for up to 1250°C (2280°F) element temperature.

Module type will determine the maximum permissible element temperature. Download our datasheet to read more.

What are thermocouples?

Thermocouples are instruments for measuring temperature, based on the thermoelectric effect – a voltage is generated when two dissimilar metals are joined, which is proportional to the temperature difference. The voltage is called Electromotive Force (EMF) or the Seebeck voltage, discovered by German scientist Thomas Seebeck. Temperature can be further calculated from EMF.
