Watt-Flex® Cartridge Heaters

The Revolutionary* Split-Sheath Cartridge Heater

• Improves heat transfer
• Reduces maintenance costs
• Reduces the cost of process heating

* patented in the United States and Canada

Conventional Cartridge Heaters

Limitations:

• Tubular sheaths with very limited expansion. They cannot be used effectively in oversized bores. Poor contact with surrounding bore results in inefficient heat transfer, higher internal heater temperature, and shortened heater life.
• Independent coil sections that can burn out leaving portions of the heater cold. Temperature differentials along the sheath can result in warping and bore seizure.
• Cool spots at coil junctions.
• A design and construction that prohibits a heated tip.
