Give machines a stronger heart with Watt-Flex®

Featured Product from Dalton Electric Heating Co., Inc.


Uneven Heat:  Unlike conventional cartridge heaters, Watt-Flex® cartridge heaters use a continuous heating coil that allows for a more uniform temperature profile.  Watt-Flex Temperature Profiles Test results highlight the superior temperature profile along the length of a torpedo probe heated by a Watt-Flex® heater. Dalton Electric - Eliminate Uneven Heating

Eliminate Bore Seizure:  Watt-Flex® cartridge heaters are warranted removable from bores because their split-sheath design prevents warping. Split-sheath construction allows the heater to expand bilaterally when energized. When de-energized, the heater contracts uniformly to ease removal from the bore.  Dalton Electric - Eliminate Bore Seizure

Cost Savings:  With all of the unique design factors, Watt-Flex® heaters last up to 50% longer resulting in fewer heaters used annually. Routine maintenance costs and down time are reduced or eliminated.  While the initial purchase price of Watt-Flex® cartridge heaters may be slightly higher than conventional cartridge heaters, the benefits of switching to Watt-Flex® are easily recognized by Maintenance Managers, Process Engineers and Purchasing Professionals who understand production costs, maintenance shop hours and the total cost of heating.

All of the benefits of switching to Watt-Flex heaters is part of  “The Dalton Difference” and can add up to valuable COST SAVINGS!   The Dalton Difference is easily recognized by Maintenance Managers, Process Engineers and those who understand production costs and maintenance shop hours.  The motivation to change such an integral process part is usually prompted by those who work with heaters daily.
