WATT-FLEX®
PROCESS HEAT PRECISELY DELIVERED
Watt-Flex® Split-Sheath Cartridge Heaters make full contact with the bore wall for fast, efficient conductive heat transfer and uniform temperature distribution. Watt-Flex® helps manufacturers:
- Accelerate equipment cycle time and increase throughput
- Deliver more consistent part quality with uniform temperature distribution
- Improve yield and cut material waste in thermally sensitive production
- Prevent bore seizure and minimize unplanned downtime
- Lower total cost of heating and improve return on investment

the dalton difference
Dalton Electric’s Watt-Flex cartridge heaters are engineered as a performance upgrade for industrial process heating, not a commodity replacement. By expanding outward when energized and contracting when cool, Watt-Flex® maintains full sheath-to-bore contact for efficient conductive heat transfer and easy removal.
This design, combined with a continuous axial heating coil and highly compacted magnesium oxide insulation, delivers higher throughput, improved finished part quality, and a lower total cost of heating.
