Finned Strip Heaters are used for both forced and natural convection air heating. It is designed using a helically wound resistance coil placed on a ceramic insulator. Remaining voids are filled with high purity magnesium oxide to increase thermal conductivity and dielectric strength. Continuous spiral fins are permanently furnace brazed to the sheath.
