Circulation Immersion Heaters

Circulation Heaters consist of Screw Plug or Flanged Immersion Heaters, depending on kilowatt rating and size, mated to a pressure vessel. All welded joints on the vessel and heater are hydrostatic pressure tested. Mounting brackets provide easy and quick installation.

Typical Applications

Low Carbon Steel Sheath

Applications include fluid heat transfer media, tar, high to low viscosity petroleum oils, asphalt, wax, molten salt, and other solutions not corrosive to a steel sheath.
Steel Sheath Heaters 8 watts/in², used for: Fuel Oils (Bunker C and Number 6)
Steel Sheath Heaters 23 watts/in², used for: Lightweight Oils, Heat Transfer Oils, Degreasing Solutions

Incoloy^® 800 Sheath

A Nickel (30-35%), Chromium (19-23%), Iron alloy. The high nickel content of this alloy contributes to its resistance to scaling and corrosion. Used in air heating and immersion heating of potable water and other liquids that are not corrosive to an Incoloy^® 800 sheath
Incoloy^® Sheath Heaters 16 watts/in², used for: Heat Transfer Oils, Liquid Paraffin
Incoloy^® Sheath Heaters 23 watts/in², used for: Forced Air, Caustic Solutions, Degreasing Solutions
Incoloy^® Sheath Heaters 48 watts/in², used for: Process Water

Copper Sheath

Mainly used in clean water heating for washrooms, showers, rinse tanks and freeze protection of storage tanks.
Copper Sheath Heaters 60 watts/in², used for: Clean Water

316 Stainless Steel Sheath

A Chromium (16-18%), Nickel (11-14%), Iron Alloy with Molybdenum (2-3%) added to improve corrosion resistance in certain environments, especially those that would tend to cause pitting due to the presence of chlorides. Applications include deionized water.
