Mica Strip Heater

Strip Heaters are an outstanding industrial heating product and are extremely effective in surface heating applications. They are composed of resistance wire, uniformly coiled and stretched inside a ceramic insulator along the length and width of the heater to ensure uniform heating.

The assembly is embedded in a stainless steel sheath to have high mechanical strength and corrosion resistance and is filled with high purity magnesium oxide to remove air pockets and thus providing excellent thermal conductivity and dielectric strength.

For air heating applications, strip heaters are incorporated with fins to maximize surface area to increase heat transfer rates and thus provides faster and more efficient heating. Finned Strip Heaters are used for both forced and natural convection air heating. Continuous spiral fins are permanently furnace brazed to the sheath.
