Achieving an operating temperature of more than 1382°F (750°C) using rod-shaped heating cartridges in a small-diameter housing can be difficult. Such heating cartridges are increasingly required for applications in fuel-cell construction, battery technology, aviation and factory automation and casting technology.

Watt-Flex cartridge heaters are warranted removable from bores by their manufacturer, Dalton Electric Heating Co. Inc., because their split-sheath design prevents warping.

Designed for maximum temperature, heat transfer and heater life, the 0.125” Superwatt optimizes heat transfer from the resistance wire to the sheath.

Watt-Flex can be manufactured with a groove along the outside of the sheath to accommodate a needle-type thermocouple for accurate sensing and control in temperature-critical processing applications such as molding heat-sensitive resins.

With heavy-duty materials of construction, immersion heaters are constructed using high-grade materials and put through a vigorous quality assurance testing procedure to ensure that each heater conforms to specification.

SPI: The Plastics Industry Trade Association is accepting presentation and speaker proposals for its educational program on advanced technologies and pressing business issues that will take place during the NPE 2015 international plastics exposition.

 Watt-Flex can be manufactured with a groove along the outside of the sheath to accommodate a needle-type thermocouple. 

Electric heater buyers can peruse the latest catalog on heating solutions from St. Louis-based Watlow in print, online or via tablets and smartphones. Available formats include a printed book, PDF file, CD and a flip book.

The 0.125" (3.175 mm) cartridge heater was developed for OEMs that required a small but high power thermal solution.
