Superthal® flat panels

These flat panels are heated by Kanthal® Super MoSi2 heating elements with the terminals either straight or 90° bent with fixed contacts. Element dimension and configuration depending on demands. The panels are designed for horizontal use.



Superthal® flat panels are commonly used in the glass industry as overhead heaters of feeder forehearths. The panels consist of Kanthal® Super molybdenum disilicide (MoSi2) heating elements integrated into reinforced ceramic fiber. The dimensions and heating element layout on each panel are specially designed.

Kanthal® can give detailed technical advice on design and installation. Installation is very simple and takes normally 1–2 days for a feeder.


The panels are specially designed to fit the requirements of each specific feeder in terms of power and dimensions. The general experiences from a great number of installations are that the energy consumption is steeply reduced, often up to 40%, and that a precise temperature control is obtained, contributing to an improved glass quality. The panels are designed for horizontal use.
