Dumbell Shaped Silicon Carbide Heating Elements

Dumbell Shaped Silicon Carbide Heating Elements

One of the earliest Heating Element designs, the enlarged cold ends of the Dumbbell style element were originally made with over sized cold ends to increase cold end cross section, lowering electrical resistance, thereby lowering cold end operating temperatures.

Modern Dumbbell Alpha Rod by contrast, employ an advance technology to keep the terminal ends cool by virtue of the decreased resistivity of the lower resistance cold end material used in the manufacturing process.

Over size cold ends are therefore no longer necessary, the old style resistance ratio was 1:3, whereas the new DB resistance ratio is 1:40. Maximum temperature is 1550 deg. C. (For Dimensions, Resistance, etc. kindly contact us):
