Manufacturing Ceramic Fiber Insulated Heaters (FIH) is not Rocket Science but it does require appropriate capital equipment, design engineering, tool fabrication and manufacturing resources. Large FIHs can require several hours of preparation wherein helically wound coils of resistance wire are precisely positioned on the mold (as shown above) prior to vacuum forming. The largest FIHs ZIRCAR Ceramics has made are these 1100OC (2012oF) rated, 480Volt, 20000 Watt, 32”ID X 36” OD X 40” L semicylinders – shown below.
