Tubular Calrod® Elements

Tubular heating elements, the most versatile of all types, are used for practically the entire range of electric resistance heating applications. A cut-a-way view showing the components of the elements is shown below:

Tubular Calrod® Elements

Tubular Calrod® ElementsThe metal sheath material and the proper size resistance wire for the heating element are carefully chosen and verified by computer calculations to insure the longest service life possible. The nickel/chromium resistor wire is then fusion welded to a terminal pin to assure a positive connection. It is centered in the metal sheath and insulated with high quality magnesium oxide,(MgO). The MgO is tightly compacted around the coil and acts as an electrical insulator. The material rapidly conducts the heat from the coiled resistor to the metal sheath and puts the heat where it is required.

Choice of Sheath Material
A selection of sheath material is available to meet an unlimited variety of applications. Standard sheath materials are: Incoloy®, Types 304 and 316 stainless steel, copper, nickel and titanium.

Terminal Construction
Tubular elements generally have a threaded terminal for electrical connection at each end. Other types of terminal connections are available.

Variety of Mounting
Methods Elements can be supplied with threaded fittings for mounting through walls of tanks, ovens, etc. Compression threaded fittings are also available for easy field installation. Rings, clips, brackets, and washers can also be attached to elements for mounting purposes.

Nickel Chromium Resistance Wire
80% nickel, 20% chromium alloy resistance wire is the heart of the tubular element. This wire must meet strict and internationally recognized standards.

MgO Insulation
Magnesium oxide insulation is carefully selected to give the best transfer of heat from resistance wire to element sheath. This allows the resistor wire to operate at the lowest possible temperature. The MgO must meet rigid specifications

Easy Bending
To put heat where it is needed, tubular elements can be formed to fit most requirements. We can form tubular elements to your exact specifications.

Long Life
Tubular heaters are designed for long life and will outlast other tubular elements in a given application. Proper application assures long life.Consult with one of our applications engineers for assistance.

Cold Zone
Virtually any cold zone can be manufactured, provided cold zone parameters are not violated.
