Electric Melting Furnaces

Rayteq's new high-powered, compact electric furnaces paired with advanced hybrid digital/analog power controls slash energy costs by melting aluminum or magnesium right at the die casting machine or molding line, eliminating wasteful energy losses from hot metal transportation, launders and holding furnaces in central melt systems. Additional advantages include higher energy efficiency, less metal loss, fewer scrapped castings, no operator heat stress, and no noise, all while virtually eliminating air quality issues. High furnace melting rates in a compact space are made possible by Rayteq's unique high power density heating elements featuring new life-enhancing materials technology. Rayteq also supplies exact heating element replacements to incorporate this new technology into older electric furnaces.

Rayteq's new electric furnaces are available in many standard models with melting rates from 250 lbs/hour to 2,200 lbs/hour, and capacities from 450 lbs to 4,200 lbs, aluminum, and are supplied ready to operate with Fleet Commander™ IDMS™ demand management system. Magnesium and zinc melting rates are available upon request.


Control Panel Features

  • Unique hybrid digital/analog furnace controls operated by custom PLC
  • Comes ready to connect to Rayteq’s Fleet Commander™ Interactive Demand Management System (IDMS™) to slash utility kW demand charges
  • Parallel-wired heating elements separately controlled and monitored
  • Individual tri-color (green-amber-red) status lamp for each element
  • Separate dedicated circuit breaker for each heating element
  • 24 volt control system for quick and easy troubleshooting
  • No water cooling required



Model DC-720 melts 720 lbs/hour

Furnace Highlights

  • New and improved high power density Rayteq heating elements for faster melting rates
  • Highest melting rates per square foot of occupied floor space
  • Designed and engineered using latest generation parametric 3D modeling software
  • All steel components fabricated in USA with numerically controlled equipment for precision fit
  • Element wiring harness isolated from furnace chamber for greater reliability
  • Improved energy efficient lining for lower utility costs
  • Baffled split crucible cover reduces energy loss


Model R-475 – Melts 475 lbs/hour


Model DC-800 – Melts 800 lbs/hour



DT Series Dual-Transport Furnaces

  • Full-power melting furnaces are available in two sizes (see downloadable PDF below)
  • Transported by forklift or by crane
  • Highly insulated for minimal temperature drop after disconnecting power cable
  • Power shut-off at furnace avoids arc damage to cable connector
  • Alarm horn sounds if furnace is lifted without disconnecting power cable
  • Separate horn sounds if furnace is not reconnected to cable within preset time--avoids chilling or freezing metal in furnace
