Mini cartridge heaters
Split sheath cartridge heaters feature a unique new construction that eliminates the failure points of conventional miniature heaters. A continuous resistor is packed into the highest density insulation and welded to the heater connections. Lead wires exit through continuous insulation rated to about 480 °C. The cartridge heaters generate heat continuously for the full length of the heater, unlike conventional cartridge heaters, which have cold spots along their length and cold sections at each end. The even heat distribution means more uniform temperatures for your process. The cartridge heaters feature a unique hot tip, allowing you reach into every place in your process that needs heat. When energized, the action of the split sheath design forces its opposing legs to expand into contact with the surrounding bore for maximum heat transfer. The result is lower operating temperature and up to five times longer life!
