Description

Strip-heater advantages for higher temperature applications are offered by NS series. 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.

Clamp-on temperatures to 1200°F
Maximum work temperature depends on the watt density of the heater. Table 1 gives a few examples of work temperatures at different watt densities. Figure C-11 of the Heater Selection Nomographs page can be used to determine allowable watt densities for other specific temperatures.

Mounting
The flat top and bottom surfaces may be flush mounted or sandwiched between two heatconducting metal parts. Straight heaters can be mounted on surfaces curved to 6" (15 cm) inside radius or larger. The heater may be field bent to minimum 3 " (8 cm) inside radius. Standard strip heater clamps and clamping bands may be used for mounting.

In free or forced air, sheath temperature to 1500°F, maximum work temperature depends on the watt density of the heater. Table gives a few examples of work temperatures at different watt densities.
