Through the patented split-sheath design and highly specialized manufacturing techniques, Dalton Watt-Flex cartridge heaters reduce your total cost of process heating by an average of 40% over other heaters.

Dalton Electric's Watt-Flex Cartridge Heaters use a unique, patented split-sheath design that expand when energized to maximize heat transfer through greater contact with the wall of the bore. Better heat transfer means less power is consumed to maintain the set point temperature, reducing operating costs.

The Watt-Flex heater construction eliminates ceramic cores typically found in conventional cartridge heaters. Dalton has developed and highly-specialized manufacturing techniques to compact high-grade MgO dielectric to its near theoretical maximum around the heater coil, which increases dielectric strength and heat transfer away from the coil which results in significantly longer heater life.

Watt-Flex cartridge heaters last up to 5 times longer than conventional heaters with less downtime for heater replacements and lower maintenance costs. Watt-Flex heaters contract when de-energized, eliminating bore seizure and the need for expensive drill-outs.
