Low Density Cartridge Heaters
| » |
SUPER POWER ELECTRICAL's LOW-DENSITY cartridge heaters line of various sheath diameters and lead terminations is used in any assembly, equipment or machines. |
| » |
The LOW-DENSITY cartridge heater design consists of a helically wound resistance coil made from nickel-chrome wire, evenly stretched and strung through holes in a round steatite ceramic insulator. |
| » |
The element assembly is inserted into a 304 stainless steel sheath. This alloy provides the best combination of physical strength and resistance to heat oxidation up to 1000 0 F (540 0 C). |
| » |
Specially selected high purity MgO is used to fill all remaining space inside the ceramic insulator to increase thermal conductivity, dielectric strength, and provide longer operating heater life. |
| » |
LOW-DENSITY cartridge heaters are used in plastic injection, packaging machinery, heat sealing, shoe machinery, labeling machines, hot stamping and liquids, plus many other types of heating applications. |
