Ceramic fiber modules are folded or stacked from ceramic fiber blankets and pre-compressed to form rectangular modules. This modular design features non-exposed anchoring to facilitate economical installation and mechanical connection. The connecting mechanism can be made of various alloys or through the use of ceramic cup locks. In addition, our modules come in the form of pre-welded or shot applications and are suitable for different mounting methods. Modules are the perfect solution for the thick wall high temperature insulation needs of industries such as heat treatment, steel, refining and petrochemical, power generation and ceramics.
