The Dalton Difference (Again)
Bore Seizure is a maintenance issue the exemplifies the Dalton Difference. Bilateral expansion of the
sheath legs of the Watt-Flex® cartridge heater produces better heat transfer, but the biggest feature
is de-energized contraction of the legs, providing ease of removal. Drilling out a seized conventional
cartridge can result in many maintenance hours in the machine shop. This cost is generally more than
the price of a new heater, so where does the benefit lie in buying a cheaper heater?
