Heating elements manufactured from APM tubes.

In the following cases, heating elements made from APM tubes give large advantages:

• In furnaces, where the carbon activity is so high, that elementary carbon can be deposited on furnace components. In such a case, there is a need to use heating elements which can work at low voltages, to avoid electrical currents on and between elements.
• When there is a need for increased heat capacity and the furnace geometry is such, that the installation of traditional heating elements is difficult to perform.
• When the heating elements are subject to mechanical influence and there is a risk for fracture of traditional heating elements.

Installations of heating elements manufactured from APM tubes have been made in a number of cases with excellent results; Increased heat capacity was easily added and the service lives of the heating elements increased. Examples of used geometries are shown below.
