What is a cast iron heating element?

A cast iron heating element is a resistance heater, usually a tubular element, that is cast directly into a solid iron body. The iron surrounds and protects the element, then carries its heat to the surface it’s mounted against. The result is a single solid part that can be shaped to fit flat platens, round barrels, pipes, tanks or custom equipment.

In a shop, warehouse, or production floor, heating equipment takes a beating. Dust, vibration, temperature swings, and long run times wear down lighter units fast. That's why industrial cast iron heaters remain a go-to choice for facilities that need heat they can count on year after year.
