Specifications

Immersion heater:
High or low watt density
Rapid heat transfer
Economic
Explosion resistant juction boxes also available

Immersion heater intruduction:

Immersion 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, immersion heaters are commonly used for heating gases & liquids such as water, oil, heat transfer fluid, and corrosive solutions.

Selection suggestion:

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.

High Watt Density Immersion Heater:

Immersion heaters are used in industrial water boilers and storage tanks. They feature high watt density for rapid heat transfer. The steam boiler heaters feature the highest quality, high nickel Incoloy sheath that provides the highest practical protection available against hard water containing minerals, scale and salts while resisting stress, corrosion, cracking, and sulphur attack. The water heater has a copper sheath and copper face plate. These heaters are not supplied with enclosures since they are normally mounted in boilers or tanks which have a surrounding enclosure for terminal protection.

Example:

 
Wattage: 5 to 18 kW Power: 208 and 240 or 480VAC, 3 Phase Watt Density: 79-184 W/in2 Sheath: 0.315" dia. Incoloy (steam boiler heater) or copper (water heater).   

Low Watt Density Immersion Heaters are also available:

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.
