HEATROD CONSTRUCTION FEATURES
Nickel Chrome Alloy Resistance Wire. This is machine wound around an MGO core and centered in the unit. The heaviest wire gauge is used consistent with thermal design to maximize resistance wire strength.
Hi Purity Solid Nickel Connector Pins. These solid Grade A pins run the full length of the heater to connect with the resistance wire at the end of the core. This design achieves the best possible pin/wire connection location for both temperature and amperage, assuring the longest heater life.
Controlled MGO Granulation & Compaction. Heatron’s swaging process provides optimum thermal transfer and electrical dielectric strength. High purity magnesium oxide (MGO) grain electrically insulates the thin space between the resistance windings and the heater sheath, for maximum heat transfer into the part being heated. During the swaging process, the MGO is evenly compacted so that the heat transfer and dielectric strength is consistent throughout the length of the heater.
Corrosion Resistant Sheath. The wall thickness and diameter of the sheath material is custom designed to give optimum swage configuration. This tubing provides the best combination of corrosion resistance, strength, and thermal transfer. Various alloys are available for special applications.
Welded End Disc. To protect the heater from external moisture or contaminants, the end disc is welded in place. During swaging, this disc is concave, thus maintaining equivalent MGO compaction density at the heater tip.
UL & CSA Approved flexible lead wire has insulation, which allow operations up to 450° C.
Innovative Lead Construction provides minimal lead end cold section and allows a variety of custom lead configurations to meet all delivery needs.
