The NSA series high temperature
strip heater features a slim
1
⁄2"
(1.27 cm) width design, ideal for
heat applications where space
is restricted. The maximum
temperature rating is 260°C (1500°F)
with Incoloy sheath material.
Applications include heating
of large tanks, vats and heating
ducts while clamped to the surface.
FEATURES
3
⁄16 " (0.5 cm) thick x 1⁄2 " (1.27 cm)
wide mini-size construction similar
to NS type. The heater design,
materials and construction give
long life for given power densities.
The Incoloy sheath encloses nickelchromium resistance wire embedded
in a densely compacted refractory
material selected for dielectric
insulation value and good heat
conduction to the sheath. The small
cross-section is often an advantage
where space is a factor.
SPECIFICATIONS
Sheath Material: Incoloy
Max. Sheath Temp.: 815ºC
(1500°F)
