Technical data

DESIGN OPTIONS

A tubular element has four basic components: a metal sheath, a helically wound coil of special resistive alloy, end seals, cold pins on each side of the coil, and magnesium oxide (MgO) insulating material. The tube is the outer casing of the heater and houses the other basic components. The cold pins protrude from the ends of the assembly to allow for
power connections.

END SEAL TREATMENTS


Backer Springfield offers multiple end seal treatments. The operating temperature of the heaters, as well as the storage, operation, and end user application will determine the appropriate seal material.

 

LEAD WIRES AND TERMINATIONS


The power connections to the heater assembly can be provided by either splicing lead wires to or directly welding terminals on the cold pins. Multiple lead wire types and terminal pin options are available.
