Globar® SD silicon carbide heating elements are engineered for maximum efficiency and durability in high-temperature industrial applications. Manufactured from high-purity alpha silicon carbide, Globar® SD elements are designed to perform optimally in temperatures ranging from below 600°C (1,110°F) to 1,600°C (2,910°F). These elements are used in a variety of atmospheres, including air and controlled environments, making them versatile for use across many industries such as glass, ceramics, electronics, and metal processing. Key features Material and structure: Globar® SD elements are made from recrystallized alpha silicon carbide grains, extruded into rods or tubes, and then bonded together at high temperatures over 2,500°C (4,530°F). This process ensures strong and uniform bonds between grains, creating elements with high mechanical strength and resistance to harsh process atmospheres. Flexible installation: The elements can be mounted either vertically or horizontally without the need for special supports, as they remain rigid even at high temperatures. Available in round rod or tubular forms, and multi-leg configurations (U, CU, W, and M types), Globar® SD elements offer installation flexibility for a wide range of furnace designs. Enhanced performance: Globar® SD elements accept higher electrical loadings compared to metallic elements, leading to potential savings in furnace construction costs. The elements maintain excellent performance under both continuous and intermittent operations. For example, at 1,400°C (2,550°F), the elements typically experience a resistance increase of only 5–6% per 1,000 hours of continuous use.
