Product Overview
  • Known for its versatility, ruggedness and dependability, tubular heaters can virtually be factory-configured to suit a variety of industrial heating applications. Tubular elements are frequently regarded as the foundation of all heating elements. The basic design consists of a resistance wire/coil precisely centered in a metal sheath. This wire/coil is surrounded by magnesium oxide to provide efficient heat transfer from coil to heating medium. Diameters are varied to give customized design and adjustable watt densities for best performance and long life. Bending radius is carefully chosen so as to give optimum performance. Tubular heating elements perform heat transfer by all three modes (conduction, convection and radiation). They are available in both single ended and double ended designs.
  • The single-ended tubular design has both terminals at one end. The opposite end is sealed. Flexible lead wires are 12 in. (305 mm) crimp connected to the terminal pin and have silicone-impregnated fiberglass over-sleeves. Maximum watt density is up to 45 W/square inch while the maximum operating temperature is 1200 degree F, so INCOLOY and stainless steel sheaths can be used.
  • The double-ended design has round cross sectional geometry, is highly adaptable for bending—especially when bending is performed in the field. Double-ended tubular elements offer several assemblages of resistor coils and thermocouples inside one sheath. They have the ability to sense the heater’s internal temperature accurately every time, or offer three-phase capability in one element. Maximum watt density is up to 120 W/square inch while the maximum operating temperature is 1800 degree F, so INCOLOY and stainless steel sheaths can be used.
