FEATURES

Single-heat rings have two

terminals for single wattage,
ON-OFF switch or thermostat.

Three-heat rings have three
terminals which split the total rated
wattage into two equal circuits. By
using a three-heat switch 1⁄4, 1⁄2 or full
wattage may be obtained. Use the
two equal circuits in parallel to
obtain full wattage. Center terminal
is common.

Refractory-insulated construction

exclusively. By far the most rugged
and best for long, dependable
service.

Easy installation. The circular
shape and the use of OMEGALUX

®

utility clamps simplifies the use of
ring heaters. Nesting rings to pack
heat in a small area can be done
by installing rings within each other.
For examples: A-651, A-802 and
A-903 provide 4050 watts within a
1031⁄32" circle.

Utility clamps.

Usually used in sets of 4 to clamp
ring elements on flat surfaces. 5⁄16"
flat-head machine screws are
normally used, with head brazed or
welded to work surface.

To order utility clamps, ask for Model
No. 6018 Clamp, $5.35 each.
