Dumbell Shaped Silicon Carbide Heating Elements the enlarged cold ends of the Dumbbell style element were originally made with over sized cold ends to increase cold end cross section, lowering electrical resistance, thereby lowering cold end operating temperatures. 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.
