The most versatile of all electric heating elements, the tubular heater is capable of being formed into virtually any configuration. The basic design consists of a helical coil of nickel-chromium resistance wire precisely centered in a metal sheath. This coil is surrounded by magnesium oxide powder which is vibration loaded to insure even density throughout the length of the heater. This entire assembly is then reduced to the finished diameter, compacting the MgO and "freezing" the coil in the center of the heater. The range of ratings, sizes, materials and terminations available makes the tubular heater adaptable to many industrial, commercial and scientific applications.

• Copper Sheath: Water heating, water solutions non-corrosive to copper.
• Steel Sheath: Immersion in oils, molten salt baths, alkaline cleaning solutions, tars and asphalt. Also suitable for clamping to metal surfaces and casting into aluminum.
• Stainless Steel Sheath: Corrosive liquids, food processing equipment.
• Incoloy Sheath: Air heating, radiant heating, cleaning and degreasing solutions, plating and pickling solutions, corrosive liquids.

Other sheath materials are also available for application considerations. Commonly specified are 316 stainless steel and Carpenter 20 stainless steel for corrosive immersion heating, copper clad steel for metal casting, Inconel for high temperature applications, and titanium for severely corrosive solution heating. Porcelain and ceramic coatings can also be provided for corrosive atmospheres in process air applications, immersion heating, or for other application considerations.

Durex Industries manufactures formed tubular heating elements for applications which require a uniform heat source over a distributed area. Tubular heaters are very versatile and can be designed with wide range diameters, lengths, sheath materials and voltage ratings. The flexibility of these heating elements allows them to be formed into virtually any shape, including precision forming for a tight fit into milled grooves of manifold surfaces. Multiple termination options are available depending on application requirements. These options include threaded stud terminals, flexible lead wire or bulkhead fittings. Customized terminations are available for harsh or high-moisture environments. The sheath of the tubular heater is available in many materials and surface treatments, such as passivation or electro-polishing for increased corrosion resistance.

These versatile heaters can also be formed and shaped into various geometries for radiant heating and contact surface heating applications. UL® and CSA component recognized elements available.

WATROD Tubular®

Single-Ended Tubular

High Temperature WATROD

MULTICOIL

FIREBAR Flat Tubular

Applications: • Furnaces and ovens • Molten salt baths • Foodservice equipment • Semiconductor equipment • Die casting equipment • Metal melt and holding • Fluidized beds • Boilers • Radiant heating • Drying and warming • Process air heating

Features •The Hotwatt Tubular Heater has built-in resistance to shock, vibration, corrosion and temperature extremes. •The heater is swaged, reducing the diameter of the metal sheath and compacting the insulation. This insures rapid heat transfer and holds the coil in position for forming.

•Many formations are available.

•Long, trouble free service.

•Made in U.S.A.

For tanks, platens and other surface heating applications, freeze and moisture protection in control cabinets, and infinite other industrial and commercial applications, OGDEN Strip Heaters offer outstanding performance in the most demanding situations. The HD Strip Heater's highly compressed refractory material provides uniform temperatures and long life in thousands of applications, including convective air heating. Adding fins increases the surface area to allow higher wattages.

A thin profile and extreme watt density capabilities of Mighty-Tuff Strip Heaters provide high temperatures with quick responses for conductive surface heating processes. Mica Strip Heaters are the most economical of all strip heater types. Applications in commercial cooking and vending equipment are typical. The Channel Heater's seamless design can provide high process temperatures. With certain configurations, Channel Heaters can be contamination proof. With the HD, Mighty-Tuff, Mica Strip and the Channel Heaters, OGDEN can supply the perfect heat source for any strip heater application.

Screw Plug Immersion Heaters, Immersion Heaters from Heaters Controls & Sensors.

Screw Plug Immersion Heaters are ideal for immersion min liquids, where space and connections are a problem.
