Overview
Continuous high-volume brazing
VAB Multi-Chamber systems are continuous vacuum aluminum brazing lines designed for very high-volume production of heat exchangers and complex aluminum assemblies. Multiple connected chambers—typically including pre-heating, brazing, cooling and unloading zones—operate under fluxless brazing conditions using magnesium activation. These systems ensure stable vacuum levels, excellent temperature uniformity and efficient throughput for large-scale HVAC&R, automotive, aerospace and industrial aluminum brazing operations.
Applications
Where VAB Multi-Chamber is used
Automotive aluminum components
Aerospace heat exchangers and structures
