Heat Cartridges

Process Heating by Cartridge Heaters – split-sheath Watt-Flex

Dalton Electric’s Watt-Flex Cartridge Heaters use a unique, patented split-sheath design that allow the heater to expand when energised to maximise 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 split-sheath design and highly specialised manufacturing techniques of the Dalton Watt-Flex cartridge heater reduce your total cost of process heating by an average of 40% over other heaters.

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