Electric Heating Elements for Clamp-On,

Oven and Air Duct Heating

CHROMALOX ELECTRIC HEATING ELEMENTS FOR CLAMP-ON

The electric heating element(s) supplied herein are ruggedly constructed and if properly installed, operated and maintained, are designed for long life and dependable, trouble-free service.

The following units are generally used in these applications: Tubular, Strip, Ring, Fin-Tubular and Fin-Strip

Users should install adequate controls and safety devices with their electric heating equipment. Where the consequences of failure may be severe, back-up controls are essential, including GFCI (Ground Fault Circuit Interrupters). Although the safety of the installation is the responsibility of the user, Chromalox will assist in identifying equipment options.

FIRE HAZARD. Since heaters are capable of devel- oping high temperatures, extreme care should be taken to:

A.Avoid mounting heaters in an atmosphere containing com- bustible gases and vapors.

B.Avoid contact between heaters and combustible materials.

C.Keep combustible materials far enough away to be free of the effects of high temperatures.

INSTALLATION

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam- age. Heater must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70.

High heating efficiency, low sheath temperatures and long heater life result when electric heaters are properly installed.

INSTALLATION – CLAMP-ON

1.Clamp strip heaters securely, along their entire length, to smooth metal surface. Use utility clamps spaced 5” apart and 5/16” stainless steel studs or oversized steel studs for clamping. Retighten following initial heat-up. Allow for expansion. When

more that one clamp is used, tighten clamps to avoid bowing of heater, poor heat transfer and possible premature failure. Leave 1/2” space between heater ends clamped in line for expansion. Do not use mounting tabs for clamping to surface.

2. When strips are clamped to tank bottom for melting paraffin, waxes, asphalt, greases, etc., one or two strips should be clamped vertically to the tank side extending above the liquid level. This is necessary to open a passage to the tank surface for the initially melted material, and prevent build-up of pressure.

3.Clamp ring heaters to smooth metal surface. Use cast iron utility clamps with 1/4” MONEL® or stainless steel studs. Retighten following initial heat-up.

4.Tubular heaters are clamped the same as strips against the metal surface.

5.Allow a minimum of 1” air space between heaters and insula- tion.
