Flanged immersion heaters are designed for direct immersion into fluids and gases, constructed by brazing or welding elements into an ANSI or plate flange. These heaters are installed via a flanged port in the tank or vessel, providing efficient heating. Mounted through bolted flanges to a process installation, they come in direct contact with the medium, such as water, liquid, oil, or gases like nitrogen and air. Heating elements are typically made of copper, steel, stainless steel, or Incoloy sheath, with standard flanges composed of carbon steel rated for 150 or 300 Lbs. Alternative flange materials and shapes are also available.
