The Duracraft™ design incorporates helically wound heavy gauge conventional wire or Kanthal™ APM powdered-metal wire. The heavy gauge wire enables higher temperature operation. The addition of self-locking ceramic spacers increases consistency and reliability under fluctuations of repeated temperature cycling. Upgrading to Kanthal™ APM powdered-metal wire allows for the highest temperature operation, large temperature swings and longer element life.

For:

• Highest Temperature Operation
• Large Temperature Swings
• 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

The Fibercraft™ design incorporates helically wound flat ribbon, conventional wire or powdered-metal wire that is embedded in the vacuum formed ceramic fiber heating element insulation. By using this unique construction, Fibercraft™ elements more than triple the effective radiating surface. The result is maximum heat dissipation, lower operating costs, decreased thermal response time, and improved temperature uniformity.

For:

• Low Temperature Operation
• Rapid Thermal Response

Ideal for LPCVD and thin oxidation processes, the Fibercraft FC-200 provides fast recovery and rapid cool down rates. These low-mass elements give you repeatable performance. Unique thermal engineering is used to increase the radiating surface, extending element lifetime. Available with heater surfaces coated black.

Vertical diffusion heating elements are available as completely new units or Thermcraft can remanufacture/rebuild your existing unit. Both the Fibercraft™ and Duracraft™ heater designs can be incorporated into new or existing vertical units. There are two options available when dealing with existing failed units; Thermcraft will manufacture a new heater coil for your existing failed unit and ship it to you to install, or you can ship your existing failed unit to Thermcraft and we will take care of the entire remanufacture/rebuild process for you and ship it back ready to use.
