Flange Heaters

Flange heaters consist of hairpin tubular elements welded or brazed into an ANSI pipe flange & provided with wiring boxes for electrical connections. Designed for use in tanks and pressurized vessels, flange heaters are commonly used for heating gases & liquids such as water, oil, heat transfer fluid, and corrosive solutions.

Be sure the element sheath material & watt density is compatible with the medium being heated. Listed below are the most common flange sizes, however, other sizes and watt densities are available. We have the capability to design and manufacture to your specifications, with a minimal lead time.

LOW WATT DENSITY FLANGE HEATERS AT 23 WATTS/ SQ. INCH

• Applications: 304SS & 316SS-lightweight oils, degreasing solutions,
  heat transfer oils.
• Incoloy - forced air & gases, caustic solutions, degreasing solutions.
• Titanium - seawater, brine, chromic acid.

STANDARD WATT DENSITY FLANGE HEATERS AT 48 WATTS SQ. INCH

• Applications: 304SS & 316SS-process water.
• Incoloy - deionized water, demineralized water.
• Titanium -seawater, brine, chromic acid, nitric acid.

Note: Explosion resistant junction boxes also available.
