Cartridge Heaters
Type H Hi Density
Type S Low Density
General Description and Construction
Type H FIREBRAND® Hi-Watt Density cartridge heaters are highly compacted by swaging. This provides a dense uniform refractory material with excellent heat transfer and electrical insulation. The FIREBRAND family of sizes is unique in uniformity of refractory density. Careful coordination of components provides the same excellent performance in all sizes at high power outputs.
Type S Lo-Watt Density cartridge heaters are time-tested conventional design with helical resistnce cails supported in ceramic cores and insulated with magnesium oxide. These units provide excelent life and performance in applications at medium and lower power requirements.
Typical Applications
Dies, platens, molds, and other applications requiring localized heat in restricted work areas with close thermal control.
