Fibrothal® prefabricated heating modules

Fibrothal® heating modules play a central role in electrifying large-scale industrial heating processes as they are specifically designed for high-temperature applications. These modules consist of metallic heating elements encased in vacuum-formed ceramic fiber (KF) insulation that can withstand temperatures up to 1,350°C (2,460°F). Fibrothal® heating modules are quick to install, and their modular setup makes them easy to tailor to specific customer needs. The lightweight design of Fibrothal® heating modules is pivotal in modernizing industrial furnaces and significantly reducing energy consumption.

Types of Fibrothal® heating modules

Modules with embedded heating

The heating element is directly incorporated into the module and requires no additional mountings.

• Can be used for almost all furnace layouts.
• In addition to panels for furnaces with flat walls, there are a variety of module designs for cylindrical surfaces.
• Maximum element temperature up to 1,150°C (2,102°F).

RAC tubes

Embedded but virtually free-radiating heating element.

• Self-supporting and/or self-stabilizing inside the furnace body.
• Maximum element temperature up to 1,300°C (2,372°F).

ROB in panel and shell design

Modules with built-in mounting system and meander-shaped heating elements of round wire, the element legs mainly running next to each other in V-form.

• Both Kanthal® and Nikrothal® alloys can be used.
• Element temperature up to 1,300°C (2,372°F).
• Possible to change the heating element.
• Long heating element length over several modules is possible, therefore far fewer terminals are required.

Meanderthal II

Heating element mountings consist of metallic hairpin-shaped parts, which are anchored in the ceramic fiber module.

• No limitation on the installation position.
• Suitable for tilting, roof heating, and round furnaces.
• Maximum element temperature up to 1,300°C (2,372°F).

Meanderthal III

Heating element mountings consist of metallic rod support and metallic holders, anchored in the ceramic fiber module.

• Elements can be replaced.
• Tilting of furnaces up to 90° is possible.
• Also suitable for round furnaces.

Special tube modules

These modules, usually multi-zone, are similar in design to the RAC tubes.

• Can also be supplied with a sheet metal shell.
• Kanthal® A-1, AF, or APM alloys are used.
• High-temperature uniformity.
• Precise temperature profiles can be achieved.
• Can be installed in any position.

Muffles

Monoblock ceramic fiber modules with embedded heating elements made of Kanthal® alloys

• Can be used for laboratory and small chamber furnaces.
• Can be heated on up to four sides.
• Maximum element temperature up to 1,150°C (2,102°F).
• Matching door modules can be supplied.
• Short assembly and heating up times.

Insulating parts

Can be supplied in the same dimensions as the special heating modules.

• FibroSiC unsupported roof modules.
• Designed to achieve self-supporting, easy-to-assemble roof insulation.
• Combination of ceramic fiber, insulation modules, and SiC tubes.
• Unsupported up to 2,200 mm at furnace temperature up to 1,200°C (2,192°F).
