Featured Product from Dalton Electric Heating Co., Inc.

Unlike conventional cartridge heaters, the Watt-Flex® Split-Sheath Cartridge Heater is manufactured with two semicircular legs that expand bi-laterally when the heater is energized. These legs make intimate contact with the walls of the bore, maximizing heat transfer, using less energy to maintain set-point temperature and significantly extending the life of the heater.

When the Watt-Flex® heater is de-energized, the legs retract to nearly their original size, allowing for easy removal of the heater from the bore. This feature makes the Watt-Flex® Cartridge Heater the logical choice of machine manufacturers for use in small, long sealing bars and large, long platens which are nearly impossible to drill out. 

Watt-Flex® cartridge heaters are warranted removable from the bore.
