Dross reduction Attachments to Furnaces e.g. Aluminum

  • Reduced Energy Costs – Energy efficiencies of 0.2 kWhr/lb for melting with no emissions.
  • Improved melting from ultra clean metal.
  • Clean melting, with dross values less than 0.5% depending on configuration.
  • No requirement for nitrogen, argon, or chemical fluxes – significantly reducing operating costs and the environmental impact.
  • Extremely small equipment footprint as shown above in Figure 1.
  • Quiet operation – Zero noise -much lower than typical, conventional plasma systems.
  • High energy density nearly four times compared to the standard
