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.

Here is a step-by-step guide that walks us through the entire process, from understanding the different types of Fibrothal® heating modules to replacement instructions.

Characteristics

Types of Fibrothal® heating modules

Type

Description

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).
