Folded cartridge heaters run more efficiently, use less power and last up to 5 times longer than conventional cartridge heaters.

The unique split-sheath design of the Folded cartridge heater allows independent, bilateral expansion of each half of the heater outward against the walls of the surrounding bore.

The result is greatly improved heat transfer under normal fit conditions of .005" to .007", assuring superior heat transfer, more uniform process heat, greater efficiency, and reduced consumption of electricity. If bores are oversized from previous use and drill-outs, the bilateral sheath expansion will maximize heater-to-bore contact for the most efficient conduction heating.
