Integrated solutions

for carbon fiber production

With the expertise from more than 70 years of thermal process technology and equipment engineering, we have entered the market for high-performance fibers. Our extensive know-how in developing and deploying continuous furnaces with precise process control is the basis for cost-effective, flexible and sustainable production technology for carbon and ceramic fibers. We offer our customers scalable production concepts for R&D, demonstrations, pilot and serial production.

The constantly growing demand for carbon fiber applications is leading to an increasing need for more cost-effective manufacturing processes and alternative precursors. centrotherm offers modular scalable process equipment for stabilization, carbonization and graphitization, as well as turnkey production lines for the manufacture of carbon fibers.

Cost and time savings by low-pressure oxidation

centrotherm low-pressure oxidation for fiber stabilization enables significant improvements in the processing of PAN precursors. Compared to the conventional circulating air process, it enables precisely matched temperature profiles as well as higher temperatures. Quasi-digital heating zones enable customized process configurations for outstanding results - even for homo-PAN fibers and with renewable precursors such as cellulose or lignin.

Advantages of centrotherm low-pressure technology

Tailored process atmosphere

Quasi-digital temperature zones and state-of-the-art and modern control technology enable a quasi-autothermal process management and a direct response on the stabilization progress.

Cost and energy savings

Low-pressure technology potentially lowers energy consumption and costs by up to 30%.

Simplified exhaust treatment

The low volume of highly concentrated off gas requires no Regenerative Thermal Oxidation (RTO) and allows direct combustion.

Reduced process time

The increased process speed results in time savings of up to 30%.

High production safety

No risk of thermal runaway thanks to processing in a closed system.

Modular turnkey production lines

centrotherm is the world's only supplier of scalable turnkey lines with oxidation, LT and HT carbonization, and UHT graphitization. Our future-proof technology for PAN, homo-PAN and alternative precursors has the potential to sustainably reduce market entry costs for carbon fiber manufacturers.
