When to Extend Cold-end
Nothing shortens heater life like open air heating.
A maintenance engineer at a battery plant was inquiring about a problem
heater in their plant. In the description of the problem he noted that he
sometimes sees the heater glowing outside the bore after experimenting
using one heater in this application versus two separate heaters for their
lead melting application that has two bore depths.
After reviewing their tool drawings we were able to recommend a single
heater with an extended cold end to prevent any heated section from
being outside the bore in an “open air heating” situation. Heaters can
quickly fail in this open air heating condition, because they over heat and
literally burn out. With an extended cold end heater, they now have
a robust heater with no heated section outside the bore.
