INDUCTION FURNACE POWER CABLES

Thermal processing of advanced materials often requires exposure to high temperatures for extended periods of time, and fine tuning a thermal profile for a highly engineered material requires substantial resources to perfect. When it’s time to make product, you need to be confident in your equipment, with each component contributing to a successful campaign. Our water-cooled power cables can stand up to the most stringent requirements for your specified application.

  • Crystal Growing - semiconductor, photovoltaic, sapphire – crystal growing operations entail lengthy furnace/puller campaigns that require consistent operation to produce high quality product.
  • Graphitization occurs at extremely high temperatures; as a critical component, your water-cooled power cables must deliver coolant and power, both safely and reliably.
  • Induction heating covers a broad spectrum of applications and materials, with varying degrees of complexity. Whether you are brazing, hardening, sintering or tempering, I²r Power can design/build a secondary conductor for your specific requirements.

BULKHEAD & PASS-THRU BUS ASSEMBLIES

As a designer and manufacturer of secondary conductors, I²r routinely works with customers to develop vacuum pass-thru assemblies that address their unique circumstances. Controlled atmosphere applications are often employed in the high-temperature thermal processing of advanced materials, and thus a reliable pass-thru method is essential. Application design elements often include:

  • Compact, robust, maintenance free design
  • Minimize/eliminate water-cooling requirements
  • Quick-change melt crucible capabilities
  • Minimize/eliminate inductive heating of adjacent hardware
  • Permanent and/or removable bulk-head capability
