Watt-Flex

IPSWICH, MA - Watt-Flex® Cartridge Heaters are warranted removable from bores by their manufacturer, Dalton Electric Heating Co., Inc. Because their unique split-sheath design prevents warping, the primary cause of bore seizure for conventional cartridge heaters, Watt-Flex® Heaters are the only cartridge heaters warranted removable from bores. If removal by drillout from a properly sized bore...

Quality Coils Produce Quality Heater

Nickel Chromium (80-20 NiCr) wire is used to form the resistance coil that produces the heat within the Watt-Flex® cartridge heater. These coils can be wound by hand or by machine, depending on the quantity of the order ... it certainly takes less time to set up and hand wind an order of ten heaters than it does to perform a machine set-up. Each gauge of resistance wire has a different resistive...

Stuck Heater Solutions: Cut Your Heating Costs

A situation was described where a 20 long heater got stuck in the bore and cost the customer many hours of down-time to remove the heater. The study said that the customer called this manufacturer for an answer to their "sticky" situation. They had two suggestions ... the first being that the customer should use two 10" heaters coming in from each side of the bore and affix a hex nut to each...

Get the Most Reliable Cartridge Heater Made Today

The Watt-Flex® cartridge heater has a hot tip feature that is unparralled by conventional cartridge heaters. Because the coil passes across the tip of the heater, it can be left unstretched to produce a true hot tip or stretched to de-rate" the tip of the heater. The hot tip is useful for very localized heat at the tip of the heater ... for applications such as probes for injection molding, heat...

Cartridge Heaters offer choice of mounting configurations.

Watt-Flex® Split-Sheath Cartridge Heaters are available with stainless steel flange, mounting bracket, NPT fitting, or puller end plug. Split-sheath construction allows each half of heater to expand independently when energized, for metal-to-metal contact with surrounding bore, maximizing heat transfer. Standard diameters range from 1/4 to 1 in., and 8 to 20 mm. Units come in lengths from 1 1/4...
