Hotwatt, established in 1952, began with the manufacturing of one product, the open coil heating element. Since then Hotwatt has expanded our product line to include cartridge, air process, immersion, strip and finned strip, tubular and finned tubular, band, foil, flexible glasrope® and ceramic heaters. We are dedicated to the design and manufacturing of resistance heating elements for a variety of OEM, industrial, medical, commercial and military applications. In addition, we can supply compatible accessory items, which enable us to offer a complete heater system.
