CHROMALOX ELECTRIC HEATING ELEMENTS FOR OVEN HEATING – AIR DUCTS (cont’d)

GENERAL INFORMATION

1.Strips of equal wattage and voltage can be series connected for a maximum of 480 volts. If a higher voltage (600 volt max.) is necessary use the same series connections and use secondary insulation bushings.

2.Use iron or steel sheathed heaters for temperatures up to 750˚F maximum sheath temperature. Use chrome steel sheathed strips for temperatures up to 1200˚F maximum sheath temperature. Use alloy or Inconel® sheathed tubular heaters for temperatures up to 1500˚F maximum sheath temperature. The sheath temper- ature is the highest temperature on the surface of the heater when operating.

3.Do not bend or form strips.

4.Use manganese nickel wire or alloy bus bar for making electri- cal connections where temperatures are above 350˚F. Insulated copper wire may be used in the cooler region.

5.Terminals should always be in the coolest part of the oven. If oven temperature is over 800˚F the terminals should be placed outside the oven if possible. If not possible, weld electrical con- nections to heater terminals. Protect terminals from welding flux.

6.Tubulars are to be mounted the same as strips and supported on 24” centers.

MAINTENANCE

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 per- son in accordance with the National Electrical Code, NFPA 70.

1.Periodically clean terminals of dust and corrosion to maintain good electrical connections and to permit rapid heat dissipation. Use airblast and be careful to avoid damage to mica insulation.

2.Check for loose terminal connections.
