Clamshell Elements

Mellen clamshell heating elements are used in our split furnaces.  The clamshell elements use the heaviest gauge wire consistent with voltage requirements. 

Power leads are doubled where they pass through insulation in the MELLEN furnaces.  Many temperatures are predicated on a heat-up rate of one to two hours when 3-4 inches of quality insulation is utilized. 

Two clamshell elements are required to complete an element.  Clamshell elements range in size from:

• .75" to 20" ID in any length
