VAB Furnaces – Vacuum Aluminum Brazing

1
2

VAB (Vacuum Aluminum Brazing) furnaces are specialized systems designed for high-quality, fluxless aluminum brazing. Technology eliminates the need for flux and uses magnesium evaporation to remove oxygen and moisture, ensuring clean and uniform brazing. VAB furnaces provide high temperature uniformity, excellent vacuum purity, and the ability to braze complex, multi-surface aluminum components. They are available in multiple configurations: batch furnaces with suspended loads, batch tray furnaces for aerospace/commercial processing, and multi-chamber continuous lines for high-volume production.

  • • Fluxless vacuum brazing using magnesium activation
  • • High vacuum purity for clean and repeatable brazing
  • • Multi-zone heating for precise temperature control
  • • Modular multi-chamber continuous line option
  • • Batch suspended-load and batch tray-load versions
  • • Optimized heater layout for uniform heating
  • • Oil-removal vacuum pre-treatment system available
  • • Suitable for complex aluminum shapes and multi-surface welds
  • • Oxygen-free brazing eliminates flux cost and contamination risk
  • • Cleaner parts after brazing (dull gray finish, no residue)
  • • Minimal corrosion-risk since flux residues are eliminated
  • • High environmental friendliness
  • • Repeatable results due to vacuum stability and uniform heating
  • • High product quality with uniform wetting and joint formation
  • • Reduced washing steps (only pre-process washing required)
  • • HVAC&R heat exchangers
  • • Automotive aluminum brazing
  • • Aviation and aerospace heat-exchanger production
  • • Railway and heavy-duty industry components
  • • Electronics and household appliances
  • • Power generation equipment
  • • Brazing of aluminum alloys in 1xxx, 3xxx, 5xxx, 6xxx, 7xxx series

System designed to meet industry vacuum-brazing and aluminum processing standards.
