Information

By using a newly developed special Kanthal® Super molybdenum disilicide (MoSi2) heating element material, the maximum temperature is now increased to 1725°C (3140°F) for Superthal® HT, enabling up to 1675°C (3050°F) furnace temperature.

Superthal® HT heating modules can be operated vertically and are available in standard sizes or as specially designed heating packages with heating modules, back insulation and stainless steel casing.

The modules are mainly used together in rows or sets in special tubular furnaces or other heating systems. Each module can be individually controlled to ensure a uniform temperature profile and fast and accurate ramping. Kanthal® can assist in designing and building special heating systems on request.

On request, Kanthal® can assist in calculating and manufacturing complete heating packages.

Characteristics

SPECIFICATIONS
The extra high temperature is achieved by using a new Kanthal® Super type of element material, combined with special supporting hooks and high grade ceramic fiber. The electric contacts are attached on the module and ready to be connected.
Vertical use only.
