Available in several diameters, lengths and sheath materials, these heaters can be formed into virtually any shape and can be brazed or welded to any metal surface. Choose specific application finned heaters or heaters for runnerless molds.
Different sheath materials are available for different applications. Options include Copper, SS 304, SS 316, SS 321, Incoloy.Tolerances: Resistance +10% – 5%, Wattage + 5% –10%, Length +/– 3%.
Tubular heating elements are available in the following diameters.
Tube dia : 8 mm, 11 mm, 14 mm, 17 mm, 19 mm.
Tubular heaters lengths can extend upto 5.8 meter +
Maximum Sheath Watt Density: 30 w / in2
NOTE: Cold zone at each end: 1-1/2†min.
Variety of mountings are available to suit the application area. Tubular heaters can be brazed or welded to different sizes of threaded flanges, plate flanges, nipples, bolts.
Tubular heaters of any diameter can be finned with steel or stainless steel finn material to increase the surface area. Finns can be spiral in shape or punched to suit the application. Designed for rapid uniform heat transfer in air heating ducts. Also used in blower type comfort heating units, recirculating ovens and other industrial processing equipment & processes requiring heated air.
The following are a few, but by no means the only, ways tubular heaters can be formed. For other shapes, please provide us with dimensional details, drawings or samples.
