Watt-Flex Split Sheath Cartridge Heaters

Dalton Electric’s Watt-Flex® cartridge heaters run more efficiently, use less power, and last up to five 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 to maximize 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.
• 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 expands 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 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, resulting in significantly longer heater life.

Watt-Flex® cartridge heaters last up to five 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.
