Immersion Heaters

​Industrial immersion heaters are designed for direct contact heating of water, oils, viscous materials, solvents, process solutions, and gases for many industrial heat applications.

And since all heat is generated within the liquid or process, virtually 100% energy efficiency is achieved. We provide a variety of immersion heater options for heating any fluid, including plain water, corrosive solutions, and highly viscous oils. Our immersion heaters can also be used for specialized applications such as high pressure and hazardous areas.
