I Squared R RR054X30X1.25 Starbar Silicon Carbide Heating Element

The RR054X30X1.25 Starbar Silicon Carbide Heating Element from I Squared R is a 54-inch overall length, 30-inch hot zone, 1.25-inch diameter RR-type Starbar made from recrystallized silicon carbide, designed for high-temperature industrial heating. With a nominal resistance of 1.06 ohms, this element converts electrical energy into heat according to W = I^2 R, enabling current-based control in demanding furnaces. Starbar elements are rated for service up to about 2,912°F (1,600°C) and are used across ceramics, heat treating, metallurgy, assaying, and incineration applications; RR Starbars are manufactured in the United States and feature a central hot zone with cold ends, built for high-density silicon carbide and robust thermal performance. The RR054X30X1.25 is one of many dimensional configurations described by overall length, hot-zone length, and diameter, allowing engineers to match furnace geometry and operating temperatures while delivering reliable long-term operation in high-temperature atmospheres.
