Dumbbell Shaped Silicon Carbide (SiC) Heating Elements are one of the earliest and most efficient heating designs. These elements feature enlarged cold ends to lower electrical resistance and maintain cooler terminal temperatures. Modern advancements in SiC technology eliminate the need for oversized cold ends by using low-resistance materials, achieving a cold zone to hot zone resistance ratio of 1:15. Silcarb’s Dumbbell SiC Heating Elements are designed for durability, with aluminum-metallized cold ends for secure electrical connections using stainless steel spring clamps and flat aluminum braids. With a maximum furnace operating temperature of 1500°C (2730°F), these elements require proper insulation for optimal performance. Their high-density composition (2.4 g/cc) ensures resistance to oxidation and slow aging, making them suitable for long-term industrial use. These elements can be mounted in any orientation and customized in various sizes and geometries to meet specific heating requirements.
