Oxidation ovens

Excellent airflow for stabilizing precursors

Oxidation ovens are crucial for the first phase of carbon fiber production, where the PAN fibers are oxidized to stabilize their structure. Our systems set industry standards and are known for their innovative technologies, which have become indispensable.

We provide the airflow you need. Depending on your preferences, ONEJOON offers different kinds of airflow systems:

• Vertical-down – typically used for small tows
• End-to-end (E2E), center-to-end (CTE) – used for small and heavy tows

Top features and benefits of our oxidation ovens

• best-in-class airflow uniformity
• best-in-class temperature uniformity
• best-in-class end seal system
• short oxidation times
• reduced downtimes and easy maintenance
  (e.g. cleaning the filters during operation)
• short heat-up time
• efficient and energy-saving

Low-temperature (LT) and high-temperature (HT) carbonization furnaces

Best-in-class temperature uniformity

Carbonization furnaces are required for the second phase of carbon fiber production, in which the oxidized fibers are converted into pure carbon fibers at high temperatures. ONEJOON's technology is used successfully in numerous production lines worldwide.

Top features and benefits of our carbonization furnaces

• best-in-class temperature uniformity
• carbonization temperatures of up to 950 °C (low temperature, LT), 1,800 °C (high temperature, HT)
• graphitization temperatures of up to 3,000 °C (ultra-high temperature, UHT)
• long service life of the muffles and heating elements
• low transmission losses
• reduced consumption of inert gas

Road to net zero: Reducing emissions

Carbon fiber technology plays a decisive role in the energy transition

Products made from carbon fibers are used in various areas to reduce energy consumption, e.g. due to their lightweight yet robust properties. They are also needed to generate and store "green" energy.

However, the process technology for carbon fiber production is in need of optimization and must become more sustainable in the long term.

Lower operating costs, smaller CO₂ footprint: Your benefits with ONEJOON furnace technology

At ONEJOON, we are constantly working on improving our systems to make them more energy-efficient and environmentally friendly. We do this through the following measures, which lead to lower operating costs and a smaller CO₂ footprint:

• excellent energy reduction strategy for the entire carbon fiber production line
• reduced energy consumption in every single process step
• integrated and customized solutions for energy recovery
