CARTRIDGE HEATERS - LOW WATT DENSITY
  Technical Data


 
Normax heating cartridges are made of three elements: an 80/20 nickel-chrome heating wire spiral, studied for the desired watt density, inserted in a ceramic insulator that resists well to temperature variations and bears good thermal conductivity, all contained in a gauged stainless steel tube.
The ceramic insulation consists in a mass of powder magnesium oxide, with a physical structure and particle dimensions that allow:
-excellent density and compactness
-perfect maintenance of the spiral’s position, even when bent or at high temperatures
-minimum oxidation
-optimal heat transmission from the wire to the metal sheath.
The heater is fed by pure nickel flexible cables, insulated with PTFE and fiberglass
APPLICATIONS
Normax cartridges are generally used in practically any cartridge heating application, depending only on the watt density needed. Their most typical applications, though, are in presses for thermo-welding, dies for footware, refrigerators, air conditioners, food-processing machinery, packaging machinery, household appliances. Also typical is the application in the heating of gases, liquids or small metallic bodies, as well as in relatively progressive heating. Very used is also the waterproof version for water heating radiators.
SPECIAL FEATURES
As Ultramax cartridges (see Ultramax options), Normax cartridges can incorporate a variety of options that include built-in thermocouple, special cable protections and special outlets, in both shape and construction (connectors, flanges, threaded fittings, with flexible, rigid, bent, liquid-proof cable outlets.
