Duracraft - Diffusion Furnace Element
Diffusion furance element for highest temperature operation and large temperature swings with the longest life.
DCHT-500 furnace elements deliver dependable performance and long life even at the highest processing temperatures. Self-locking spacers and superior element design reduce the possibility for element sag. Like the DC1300, power is balanced between center and end zones, providing precise temperature uniformity at varied temperatures while reducing heat loss. The DCHT-500 includes heavy gauge, Kanthal™ APM powdered-metal heating wire for the longest life available and decreased element sag.
The DCHT-500 is a must for well drive, field oxidation, LOCOS, and other long, high-temperature processes.
The Benefits of Kanthal™ APM Powdered-Metal Wire
Kanthal™ APM powdered-metal wire increases the overall effectiveness of a heating element in high temperature applications. At 1100°C, powdered metal wire lasts twice as long as conventional heating element wire. At lower temperatures, the difference is even greater. At high temperatures, powdered-metal wire also shows superior resistance to sagging. The chart shows relative sag between conventional-alloy heating elements and powdered-metal elements. Powdered-metal wire also has a higher tolerance to corrosive atmospheres, making it a better choice for processes employing HCI.
