Flat ceramic fiber heaters consist of an iron-chrome-aluminum (ICA) heating element and a thick layer of ceramic fiber insulation within a non-curved housing.  They are manufactured in a variety of shapes and sizes. The most common geometric shapes for flat ceramic fiber heaters are square and rectangular, but other shapes can be custom-configured depending upon the application. Flat ceramic fiber heaters offer faster heat up, greater temperature uniformity, faster recovery rates, and faster cool down time then most other heater types.
