With over 100 years of experience in advanced ceramic materials, NGK the global market leader in ceramic substrates and filters for the automotive industry has applied its unmatched expertise to industrial hot‑gas treatment. The result is Cerallec, a ceramic hot gas filtration system engineered for high‑temperature operation, outstanding filtration efficiency, and a remarkably compact footprint.

Cerallec enables direct filtration of hot process gases up to 600°C, while its ceramic honeycomb filter substrate offers thermal resistance up to 900°C, ensuring exceptional durability and stability even in extreme environments. The inherently non‑flammable, corrosion‑resistant ceramic structure delivers long service life and highly reliable performance under demanding thermal and chemical conditions.

The system’s compact architecture approximately one quarter the size of conventional bag filter systems simplifies integration into space‑constrained industrial settings. At the same time, Cerallec offers significantly easier maintenance and much faster filter replacement compared to conventional filtration technologies, resulting in substantial reductions in operational downtime.

By eliminating the need for gas‑cooling steps, Cerallec supports sustainable process optimisation, reducing energy losses and enhancing overall process efficiency. Its ability to recover valuable particulate materials further contributes to circular‑economy strategies, transforming filtration into a value‑adding component of industrial production.

With over 400 installations across multiple industries, Cerallec stands as a proven, future‑ready technology for cleaner, safer, and more resource‑efficient high‑temperature gas treatment.
