Chromalox OCE Open Coil Element assemblies are specifically designed to fit inside standard 2 or 3" Schedule 40 NPS pipe for use in tank and pipe heating. They can also be used inside metal tubing. (Requires 1/8" min. clearance between ceramic and inside tube wall.)
An OCE heater assembly installed inside a
Schedule 40 NPS pipe provides uniform heat
over a large surface area. This method of
indirect heating lowers the watt density or heat
flux on the surface area of the pipe in contact
with the heated media, reducing the tendency
to coke or breakdown heat sensitive materials.
Rugged Construction — Insulating supports
are made of high density electrical ceramic
Easy Installation— Only 3 feet is required for installation or removal in cramped areas
Highly Flexible — Can be bent in a vertical
plane on a minimum 12" radius
Continuous Support Bar positions the ceramic insulators and provides sufficient rigidity for
handling and installation in pipe
Heavy Gauge Bus Bars provide spacing of
heated section away from terminal area
Heavy Gauge Resistance Wire provides reliable
service and long element life
Special Ratings and Lengths available
CAUTION — OCE elements should never be
mounted in a vertical position as the
resistance wire will sag causing uneven heating
and short circuits. Allow 3/8" per foot of
heater length for expansion. Users should
install temperature regulating controls, fusing
and backup safety devices.
