Flange Immersion Heaters
SK Convection is a leading manufacturer of electric flange immersion heaters for high-power industrial and process heating applications.
Flange immersion heaters are designed for direct heating of liquids in tanks, vessels, and pressurized environments. These heaters are typically inserted horizontally, allowing fluids to reach target temperatures quickly. They are an economical solution for large-volume heating in equipment like boilers, chillers, and chemical reactors.
