  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.
