The patented split-sheath design of the Watt-Flex cartridge heater
reduces your heater change-out costs by preventing heater bore seizure.
Dalton Electric will replace,
free of charge, any Watt-Flex Heater that cannot be withdrawn from
the bore.
| What causes conventional heaters
to warp and bind? |
| |
In conventional cylindrical heaters,
temperature can vary from one side of the heater diameter to
the other. These differentials are caused by heat deflection
within a close fitting bore, and are the most frequent cause
of heater warping and binding during removal. |

How the Watt-Flex
Split-Sheath prevents bore seizure:
With the Watt-Flex heaters' unique split-sheath design,
each half of the heater expands and contracts independently. |
 |
|
| |
| |
When energized, the heater expands
to make intimate contact with the bore wall. When de-energized
the sheath contracts for ease of removal:
Dalton Electric's standard warranty covers the removal of Watt-Flex
Heaters from bores, provided that the bore fit is a minimum of
0.005" and there is no bore contamination to cause seizure. |
