Electric Heaters for Heating Flowing Gases To 1000 F

Examples of air heaters
(click for larger view)

Do you need a small, compact electric heating system that can heat flowing gas or air up to 1000 degrees F.?

You may want to consider an inline "air process heater".

These fabricated (usually custom) electric heaters are self-contained, provide inlets and outlets, wiring,  sensors to measure internal temperatures, and are available in a variety of materials.

Air Process heater provide hot air and gas up to 1000^oF (540^oC) with infinite control by varying the voltage and air velocity supplied.

Units are fitted with a tubing “T” for convenient power lead outlet, while larger diameters can be supplied with post terminals on the sheath for direct electrical connections.

Designs can accommodate male or female NPT threaded fittings, hose adaptors, flanges, or custom fittings to your specifications.

Typical Air Heater Construction

Construction

1. Optional stainless steel bushing. 
2. Ceramic coil support.
3. Resistance element.
4. Stainless steel sheath. 
5. Silver solder.
6. Fiberglass insulated leads. 
7. Epoxy seal.
8. Copper tee.
9. Heliarc weld.
10. Optional brass bushing.

To properly size and select an air process heater:

• Determine the volume of air or gas(SCFM) you will be heating. 
• Determine temperature rise in degrees Fahrenheit(􏰁ToF).
• Calculate wattage required as follows:
• Watts = SCFM x delta-T ^oF / 3

Take into consideration the physical size requirements of your application and determine from the specifications chart for each size, the air heater best suited for your application.

Summary of Features:

• Exit air temperatures to 11000^oF (540^oC).
• Standard pressure rating is 80 psig at room temperature. 
• May be used with recirculating air up to 250^oF (121^oC).
• Designed for horizontal use.
• For use with clean, dry air.

Industrial Electric Immersion Heaters

Electric immersion heaters are used in a myriad of industrial applications. From drying industrial gasses, to freeze protecting cooling tower sumps, to heating acids in plating applications, the versatility of electric heating element can save time, energy and space.

Industrial immersion heaters are used to directly heat a standing or moving fluid by using electric heating elements. There are three primary types of industrial electric immersion heaters; screw-plug heaters, flanged immersion heater, and over-the-side heaters.

At the heart of industrial immersion heaters are the individual heating elements, normally constructed from a stainless steel or Inconel tube containing a magnesium oxide filler and a nichrome resistance wire. Current is applied to the wire which produces the heat, while the compacted magnesium oxide powder provides the electrical insulation, and the metallic tube provides the physical protection.

Have You Considered a Cast-in Heated Part?

When OEMs (original equipment manufacturer's) look for the best way of adding heat to their equipment, they're faced with the same choices - clamping, bonding or inserting. But there's another, more efficient and productive way to go - cast-in aluminum or bronze heaters.
