Components

TRI .260" Dia. Round Cross-Section • INCOLOY ® Sheath • 175 - 2,500 Watts • 120 and 240 Volt • 30 W/In 2 • 1600°F Max. Sheath Temp. Applications Versatile tubular elements can be designed for use in most applications. See guidelines in the Tubular Heater Overview section. Advantages The metal sheath isolates and protects the resistor wire from the environment. At the same time it maximizes heat transfer capability to the work. Tubular elements can be bent to put the heat where it works best. Features Type 28 Terminals — Heliarc-welded to the cold pin. See terminal detail drawing in the
