Kamlrok® Heaters

These unique heaters are constructed of a rust-resisting iron sheath with optional chrome steel sheaths available. They are precision pieces of equipment proven to be suitable for continuous duty applications. Heater reliability is assured by high quality nickle-chromium resistance wire, which is embedded in a special ceramic formula developed for long life with excellent heat conductivity. This refactory insulation is compressed and then cured in high temperature ovens to insure maximum quality.

The primary application of ring & disc heaters is the heating of flat surfaces: tank bottoms, melting pots, hot plates, platens, dies, molds, coffee urns, vacuum formers, oil vacuum pumps (diffusion pumps), incubators, vulcanizers, ovens, and resistive load banks.

Ring & disc heaters should be clamped firmly to the application surface. Small diameter disc heaters can be nested inside larger ring heaters to increase heating capacity. Center holes of all heaters accomodate positioning of the heater and facilitate mounting to threaded studs welded to the surface to be heated. Utility clamps are positioned over the heater and bolted down upon the threaded studs. The studs can also be through bolted vs. welded. Tighten clamps wrench tight and then back off 1/2 turn for good expansion.

When the application requires heating of a permanent, fixed surface, any air gap between the heater and this surface will greatly reduce the heater efficiency, and will develop hot spots on the heater surface that are detrimental to its life and serviceability. Heaters should be clamped firmly to the heated surface so they cannot readity "expand away" from this surface.

Resistance wire is precision wound.
O.D. tolerance on all ring heaters is 1/16 inch under nominal size +1/64th.
I.D. tolerance on all ring heaters is 1/16 inch over nominal size +1/64th.
Thickness is 5/16th inch +-1/64th.

On all ring heaters are located 5/8th inch from outside edge on radius of heater. Standard terminals are made of cold rolled steel and oxidized in a controlled atmosphere to keep them from rusting. Terminal thread size 8-32. All ring heaters are dished 1/2 degree from the center of the outside edge. This makes good contact possible when heaters spring down tight on the surface to be heated.

• All sizes are available without center holes (blank).
• No three heat under 3" O.D. 3 heat rings (3 terminals) which divide the total wattage into two equal circuits for a 3 heat switch (1/4, 1/2, or full power application).
• Dished heaters curved to fit convex surfaces with the following radii: 3/16, 1/4, 3/8, 1/2, 7/8, 1-1/8, 1-1/2, and 2.
• Over 250 Volts available: 120 or 240 Volt are standard.
• Nickle plated terminals are available.
