CCEWOOL® PCW Module HD 2912

CCEWOOL® Polycrystalline Wool Fiber Module HD 2912 is made of Polycrystalline Wool Fiber Blanket. This module is designed specifically to meet the insulation requirements of all fiber lining furnace between 1300 ℃ (2372 ℉) and 1500 ℃ (2732 ℉). CCEWOOL® Polycrystalline Wool Fiber Module HD 2912 is equipped with various anchoring systems and can be quickly, easily, and efficiently installed on most furnace linings. CCEWOOL® Polycrystalline Wool Fiber Module HD 2912 has the advantages of good corrosion resistance and long service life.

We can produce alumina fiber composite module made of CCEWOOL® Polycrystalline Wool Blanket and CCEWOOL® Ceramic Fiber Blanket 2600 which is more cost saving while meeting the working temperature.

Composite Module A: Module made of CCEWOOL® Polycrystalline Wool Blanket and CCEWOOL® Ceramic Fiber Blanket 2600 through cut, composite, and extrude according to a certain size. It is a high-temperature refractory lining product developed and manufactured specifically for 1200 to 1400 ℃ high temperature furnace.

Composite module B: All hot surfaces are CCEWOOL® Polycrystalline Wool Blanket, cold side CCEWOOL® Ceramic Fiber Blanket 2600.
This product greatly improves the utilization rate of Polycrystalline Wool Blanket, fully utilizing it on the firing side. This can increase the operating temperature of the module while not increase the usage of PCW blanket. The advantages of Polycrystalline Wool Blanket are fully utilized and the service life of module is extended. 
According to practical applications, the thickness of the hot surface Polycrystalline Wool Blanket layer can be adjusted to meet different furnace temperature requirements.

Composite Module C: The hot surface is red and is made of CCEWOOL® Polycrystalline Wool Blanket. It can fully utilize the high-temperature resistance performance of Polycystalline Wool Fiber, and improve the service temperature and lifespan of the module. The cold surface is white and is made of CCEWOOL® Ceramic Fiber Blanket 2600. It can be hardened at high temperatures, to ensure a sturdy structure. The thickness of the hot surface Polycrystalline Wool Blanket layer can be adjusted to meet different furnace temperature requirements.


  • 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.
