A Series Ring Heaters

Item# A-20-33/120

A Series Ring Heaters A Series Ring Heaters
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 10 31/32" 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.
