Sealing Success with Watt-Flex® Cartridge Heaters

Featured Product from Dalton Electric Heating Co., Inc.


Packaging machines generally utilize smaller diameter heaters that extend some considerable length through the sealing bar.  Over time a conventional heater will seize up in the bar due to warping, uneven heating and contamination. The small diameter heater is very difficult to remove without damaging the bar and, if drilling out is required, the likelihood of ruining the bore is high.  The Watt-Flex cartridge is warranted to be removable and will not cause damage to the bore.

Conventional cartridge heaters are manufactured with a varying number of resistance cores, depending on the length of the heater.  They are wired in parallel and segments can burn out independently, causing a cold spot on the sealing bar and rendering the bar incapable of a consistent seal.  The continuous coil construction within Watt-Flex ® Cartridge heaters solves problematic junction failure, keeping production running!
