Round Tubular Heater

Calrod Watrod
Milled Groove Metal Tubular Heaters

Tubular Heater CALROD / WATROD Single- and Double-Ended Elements.  Versatile and economical, the tubular heating element lends itself to virtually the entire range of immersion and air heating applications.

Double-ended tubular heater elements can be formed into spirals, compounds, multi-axis, and multi-planes from 36 common bend configurations. Custom bending with tighter tolerances can be made to meet specific application needs.

Please see the pictures and descriptions below for all the options:

We can ship any of the above formations from stock by using a modified stock unit.  If we do not have the right tubular calrod in stock, we can ship a custom made unit quickly. Finned or Non-finned.

We stock and supply various diameters, voltages, and watt density to cover the majority of application needs.

 

A variety of mounting and termination options are available.
