  • Element Materials:
    • 2200°F (1204°C) Elements: High quality Kanthal A1 wire, consisting of an alloy of iron, chromium, and aluminum. Provides high-temperature service and long-life performance
    • 1850°F (1010°C) Elements: 80 Ni/20 Cr wire, known for it’s reliability for decades
  • Embedding:
    • 2200°F (1204°C) Elements: supplied with open windings or supplied embedded.
    • 1850°F (1010°C) Elements: supplied with open windings or supplied embedded.
  • Lead Length:
    • 18 in. Standard.  Other lengths available upon request
  • Element Clearance:
    • To achieve maximum element life, provide at least 1/8 in. radial clearance per inch of tube diameter when heating process tubes.  For example: Provide at least 3/4 in. clearance on each side when using a 6 in. diameter process tube
  • Element Life:
    • Avoid rapid voltage fluctuations and temperature changes to obtain optimum element life
  • Voltage Limits:
    • Elements may be connected in a series to accommodate higher voltage, however, operation at 440 volts is not recommended due to dielectric properties for the spacing and temperatures being used
  • Diameter Tolerance:
    • Due to changes in dimensions when fired, element diameters may vary from 1/8 in. on smaller units to 3/8 in. on large ones
  • Atmosphere Cautions:
    • Contact one of our engineers regarding unusual applications, especially when corrosive atmosphere conditions exist
  • Price Quotations:
    • Consult one of our engineers to obtain a cost quotation for specific requirements
