Cartridge Immersion Heaters
Hi-Density Cartridge Immersion Heaters are designed for heating water and other liquids. The high watt density capability of this heater permits greater heat dissipation in a given area than would a tubular immersion heater. However it is important to note that allowable watt density depends on the material being heated. For water heating watt densities of several hundred watts per square inch are possible while oil heating may be limited to 5—to 20 watts per square inch.

Watt-Flex Replaceable Immersion Heaters
• Clean and safe.
• Heater never comes into contact with tank contents.
• Easily replaced without draining the vat or tank.
• Watt-Flex heater contracts when de-energized for easy removal.
• Stainless-steel sheath accommodates standard diameter flanged Watt-Flex cartridge heaters from 5″ to 72″ lengths.
• Solid Construction. Stainless steel sheath with a welded end cap and NPT fitting that screws into and becomes a permanent part of the tank or vat to be heated
Easy Heater Change Out
The flanged Watt-Flex cartridge heater is secured to the NPT fitting with two screws.
To replace the immersion heater, simply remove the screws, and slide out the de-energized heater.
