Profiles

As a specialist in efficient relining, we're not only qualified to maintain your kiln, but to improve it using our products. With our patented components made of CFC, we are setting new benchmarks here. Our L-, U- and h-shaped plate-setters for the construction of insulation lining are very strong and extremely rigid. They can easily be connected to form complex structures using screw connections or plug-in connections. Our double-L plate-setter is the innovative solution for a longer door insulation service life, as the edges of the door are perfectly protected and the insulation permanently remains in the intended position.

You benefit from these advantages:
  • Relining the hot zone as a comprehensive service
  • Plate-setters made of perfectly matched materials
  • L-, U- and h-shaped plate-setters available
  • Innovative double-L plate-setter for door insulation
  • Greater efficiency and longer service life of your kiln

Radial Fans / Convection Fans

As a specialist in efficient relining, we're not only qualified to maintain your kiln, but to improve it using our products. With our patented components made of CFC, we are setting new benchmarks here. Our CFC radial fans have been used successfully for years. They are characterized by application options in many atmospheres thanks to considerably less weight in comparison to steel and considerably greater effectiveness compared to "paddle fans."

You benefit from these advantages:
  • Significantly lower weight
  • Maximum operating temperature at full revolutions (no throttling required)
  • No creep, no deformation and no embrittlement equals longer service life
  • More even temperature distribution and better heat transfer
  • Improved energy and process efficiency
  • Significantly higher efficiency than simple “paddle fans”
  • One-piece impeller design, no screws and no joints
  • Given the improved efficiency, hydrogen can be replaced with nitrogen

Recuperative Burners

Ceramic recuperative burners, because of their enlarged surface area, function as an integrated heat exchanger for preheating the combustion air from the combustion exhaust gases – among others - in fully ceramic systems for the indirect heating of heat treatment furnaces. With our variants CarSIK and IntrinSiC®, materials are available, which ensure a high level of efficiency due to excellent material combinations. The material IntrinSiC® (3D-printed RBSiC) enables short delivery times and a high level of complexity in the design.

You benefit from these advantages:
  • Possible RBSiC-Variants: CarSIK, IntrinSiC®
  • High oxidation and corrosion resistance
  • Very good thermal shock resistance
  • Unique in the world: 3-D printing with IntrinSiC®
  • (Short delivery times, high design flexibility, elimination of cost-intensive model and mold costs)
