Industrial Heaters & Heating > Watt Flex Split Sheath Cartridge Heaters

Revolutionary Watt-Flex® Split-Sheath Cartridge Heater
Watt-Flex Cartridge Heaters run more efficiently, use less power and last up to 5 times longer than conventional cartridge heaters.

  • Hot Tip or Cool Tip Option
  • A single continuous heating coil ensures a uniform temperature profile.
  • No sections to burn out as in conventional cartridge heaters.
  • Split-sheath expands tomaximize heat transfer and contracts when cold for easy removal from bore.
  • Ideal for use in oversized bores. Eliminates need for tight fits, tight tolerance bores.
  • Watt-Flex's tightly compacted MgO dielectric accommodates higher watt densities - up to 50% higher warrantable heat densities than conventional heaters.
  • Watt-Flex's tightly compacted MgO dielectric accommodates higher watt densities - up to 50% higher warrantable heat densities than conventional heaters.
  • External Thermocouple Option- a Watt-Flex exclusive-provides more accurate temperature at the point of heat transfer to host metal.

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.
