VAB Furnaces – Vacuum Aluminum Brazing
Vacuum aluminum brazing furnaces using fluxless technology with magnesium activation, offering clean, repeatable, oxide‑free brazing for aluminum heat exchangers and
VAB Line – Vacuum Aluminum Brazing Continuous & Batch Systems
The VAB Line consists of multiple furnace configurations designed for vacuum aluminum brazing using fluxless technology. As shown in the catalogue, magnesium activation is used to remove oxygen and moisture, improving vacuum purity and allowing clean, uniform brazing of aluminum components. The line includes multi-chamber continuous systems for high-volume production, batch furnaces for aerospace and commercial processing, suspended-load systems for efficient heat distribution, and vacuum oil-removal furnaces for pre-cleaning before brazing. The technology supports complex shapes, multi-surface joints, and a wide range of aluminum alloys.
