Higher Watt Densities and Operating Temperatures

Watt Flex heaters produce up to 50% higher warrantable watt-densities than conventional heaters and can operate at much higher temperatures - up to 1850 degF (1000 degC).

The Watt-Flex Cartridge Heater is a high-quality tubular heating element bent back on itself and swaged into a cylindrical format. Dalton manufactures heaters using an incoloy sheath, high-purity magnesium oxide, nickel chromium resistance wire and stainless steel terminals.

Special filling methods and equipment compact the magnesium oxide inside and around the resistor coil to extreme density. Unlike conventional heaters, Watt-Flex cartridge heaters have no ceramic core that can crack during swaging. Therefore, swaging further compacts the magnesium oxide to virtually maximum density, which yields high dielectric strength and efficient internal heat conduction.

Watt-Flex Cartridge Heaters run more efficiently, use less power, last longer and are much simpler and faster to replace than conventional cartridge heaters.
