CCEWOOL® Ceramic Fiber Module is made from spun refractory ceramic fiber blanket, mechanically processed, and produced according to customer drawings. The product is pure white in color, with uniform dimensions, and can be directly fastened to the steel plate anchor pins on the industrial kiln shell, providing excellent fire resistance and insulation, thereby improving the overall refractory insulation of the kiln. 

We can design and manufacture modules and shaped modules of corresponding specifications for customers based on the kiln type and specifications, and we can also produce modules of various specifications based on customer-provided drawings.


  • Ultra-Low Shot Content

    Shot content is a crucial factor in determining the thermal conductivity of fibers. Using imported high-speed centrifuges, our fibers achieve ultra-low shot content, demonstrating excellent thermal performance with low thermal conductivity and superior insulation properties in continuous high-temperature environments.

  • Minimal Shrinkage Rate

    Strict control of harmful impurities is essential for reducing thermal shrinkage and enhancing heat resistance. Through rigorous raw material management, we reduce impurity content to below 1%, ensuring low thermal shrinkage and high heat resistance in our fiber modules.

  • Maximum Tensile Strength

    Tensile strength refers to the fiber module's ability to resist breaking under tension. The fiber blanket is folded according to specifications and compressed with a 5t press, then packaged under compression. It has excellent elasticity, effectively withstanding impacts in harsh environments and significantly extending its service life.

  • Lowest Thermal Conductivity

    Through strict quality control and high-standard production processes, CCEWOOL® minimizes shot content and meticulously controls bulk density, achieving the lowest thermal conductivity. This provides customers with exceptional insulation performance and more efficient energy-saving solutions.

Features of Ceramic Fiber Module

  • Excellent Chemical and Thermal Stability

    CCEWOOL® RCF Module offers outstanding chemical and thermal stability, ensuring reliable performance and longevity even in harsh environments.

  • Low Thermal Conductivity and Capacity

    The module features low thermal conductivity and low thermal capacity, which enhances its insulation efficiency and reduces heat transfer, resulting in significant energy savings.

  • Versatile Arrangement Support

    Supporting both soldiers-march-based and assembly-based arrangements with various forms of anchors in the back of the module, it provides flexibility in installation methods.

  • Gap-Free Installation

    After unbinding, the module compresses in different directions to eliminate gaps, ensuring a continuous and effective insulation layer.

  • Resistance to Mechanical Forces

    The elastic fiber blanket resists external mechanical forces, maintaining its integrity and insulation performance even under stress.

  • Compensates for Furnace Shell Deformation

    The elasticity of the fiber blanket compensates for any deformation of the furnace shell, preventing gaps between modules and ensuring consistent insulation.

  • Lightweight and Low Heat Absorption

    The module is lightweight and absorbs less heat, making it an efficient insulation material that is easy to handle and install.

  • Strong Energy-Saving Effects

    Its low thermal conductivity provides strong energy-saving effects, reducing energy consumption and improving overall efficiency.

  • Thermal Shock Resistance

    The module can withstand any thermal shock, ensuring durability and reliability in fluctuating temperature environments.

  • No Drying or Curing Required

    The lining requires no drying or curing, allowing it to be ready for use immediately after installation, saving time and simplifying the installation process.

  • Protected Anchoring System

    The anchoring system is positioned away from the hot surface, keeping the metal anchor members at relatively low temperatures to prevent overheating and ensure stability.
