APPLICATIONS
Versatile tubular elements can be
designed for use in most applications.
See guide lines in the Tubular Heater
Overview section
at
omega.com/heaters
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 3 Terminals: Heliarc-welded to
the cold pin. See terminal detail drawing
in the Tubular Heater Overview section
at omega.com/heaters
Work Temperatures: See Tubular
Heater Overview section at
omega.com/heaters
Bending: Customer’s minimum
bending inside radius is 1
5
⁄16". See
bending requirements in the Tubular
Heater Overview section at
