Advantages
Higher Temperatures, Faster Production Rates
Because Type CIR's patented construction and high watt density capability let you put more
heat in less space.
Shock and Vibration Resistant Tightly compacted
refractory insulation makes CIR heaters suitable for severe applications.
Even Temperature throughout the heater's length is
produced by the uniform winding of the wire on the smooth supporting core. Close and even
spacing between wire and inside of sheath is maintained for good heat transfer. Tight
spacing between turns permits the use of largest gauge resistance wire.
Excellent Oxidation and Corrosion Resistance is
provided by special Chromalox alloy sheath. Thermal expansion characteristics of sheath
and refractory are closely matched.

3/8" Dia. Cartridge heaters can be sleeved to
fit 1/2 and 5/8" diameter holes, allowing one
diameter to fit most applications.
3/4" I.D. Sleeves permit installation of type
CIR high watt density heaters in 1-1/4"
diameter holes to replace old style large diameter
heaters.
Makes Removal of heaters easier. No more drilling,
hammering, etc.
