What is a Flanged Immersion Heater?

A Flanged Immersion Heater is an industrial heating device that uses tubular heating elements bent into hairpin shapes and welded or brazed into a flange. The flange is bolted to a matching flange welded to a tank or vessel wall, allowing the heater to be directly immersed in liquids or gases. This direct immersion provides efficient heat transfer, ideal for heating fluids in tanks and pressurized vessels.

Key Features & Benefits

  • Robust Construction – High-quality tubular elements welded into ANSI-standard flanges ensure durability and reliability.
  • Wide Temperature Range – Can operate up to 1200°F (650°C) depending on medium and design.
  • Custom Wattage & Sizes – Available in a variety of power ratings up to hundreds of kW and flange sizes up to 24 inches or larger.
  • Efficient Heat Transfer – Direct immersion heating improves energy efficiency and temperature control.
  • Versatile Flange Options – ANSI flanges with various pressure classes (150, 300, 600 lb) and materials like stainless steel, carbon steel, or Incoloy.
  • Integrated Safety Features – Options include thermowells for sensors, baffles for element support, and NEMA-rated enclosures for terminal protection.

Industrial Applications

  • Oil & Petrochemical Tanks – Preheating crude oils, heating corrosive liquids, and process fluids.
  • Chemical Processing – Heating reactors, storage tanks, and aggressive chemical solutions.
