Cartridge Heaters - Stuck with Bore Seizure?

Featured Product from Dalton Electric Heating Co., Inc.

Conventional cartridge heaters require a tight fit with the bore to provide conduction heat transfer. Unfortunately, this often causes the heater to become hopelessly seized in the bore, resulting in hours of maintenance time and machine down-time, exceeding the cost of several heaters.

Watt-Flex cartridge heaters are made with a split sheath construction. When energized, the legs expand bi-laterally, providing wall-to-wall contact with the bore to maximize heat transfer, allowing the heater to run cooler to maintain the set-point temperature. Cooler running heaters last longer.

When the Watt-Flex cartridge heater is de-energized, it contracts to nearly its original size, allowing ease of removal. In fact, the Watt-Flex heater is the only cartridge warranted removable from the bore.
