Heating Elements

Hi-Temp Products has operated an in-house element fabrication shop for more than 25 years with capabilities to produce a broad range of electric heating element designs and configurations. Our heating elements are made to electrical, physical and atmospheric specifications. As a recognized aftermarket service provider, we’re accustomed to supporting clients who’s furnace equipment is no longer supported by OEMs or outside of OEM Service Agreements and routinely pay to have our Customer’s element shipped to us for characterization and proposed equivalent replacement. We retain an extensive database containing hundreds of furnace OEM heating element specifications. With 75+ years of cumulative application engineering experience, Hi-Temp Products has the capacity to provide application design and engineered solutions for new designs, replacements, upgrades and emergent repair for both new and existing equipment.

When dealing with element temperature 50 to 1850°C (120-3360°F) Hi-Temp can manufacture metallic heating elements to any specifications and with short delivery times. Our metallic heating elements are produced using superior quality alloys produced by industry trusted Suppliers like Kanthal Sandvik thus outperforming in all temperature ranges. We can produce in both either round wire, ribbon or strip form and in both Ferritic (FeCrAl) and Austenitic (CrAl) alloys. Below are some of the common elements we produce right here in the USA.

When element temperatures up to 1625°C (2927°F) are required, Silicon carbide (SiC) heating elements are a desirable option with an impressive peak power density of 50 watts per square inch. Electric furnace heating with silicon carbide elements is economical, dependable, clean, quiet and safe. There are no fuel storage problems, no worries about fuel availability and no noxious exhaust products to be ducted away. Silicon Carbide equipped furnaces are versatile. They handle a wide range of products and atmospheres efficiently, and temperatures can be controlled as closely as you like. Silicon carbide heating elements are rigid throughout the range of operating temperatures so they can be installed horizontally or vertically without any additional supports. The single ended connection types allow even greater flexibility in furnace design. They can be installed through side walls or rood, or project up through the hearth or used to heat furnaces that are too wide or too long to span with conventional elements.

Almost all high-temperature vacuum furnaces are electrically resistance heated.The choice of a heating element material depends largely on operating temperature but these elements are most commonly made from high temperature / low vapor pressure materials. This includes refractory metals like Molybdenum and Tungsten as well as Titanium, Tantalum and Graphite. Hi-Temp Products can supply shaped and flat pattern elements and produce elements of all sizes and configurations including rod, strip and round wire.  We form, twist, coil, weld, machine and grind components for new designs, replacements, upgrades and emergent repairs.
