Brazing furnace EV/CAB

chamberpreheatingelectric

Overview
Continuous EV/CAB furnaces perform controlled-atmosphere brazing of aluminum components using a stainless-steel mesh conveyor driven by a variable-speed drive. The CAB process raises assemblies to brazing temperature in an oxygen-free nitrogen atmosphere to ensure uniform part temperatures and consistent joint formation.

EV/CAB — furnace designs for e-mobility
EV/CAB systems are engineered to braze large-size car battery coolers and other aluminum heat exchangers used in electric mobility. Configurations are available to support high-volume continuous production and varied part sizes.

• Radiation CAB Furnace: Suited to continuous processing of similarly sized parts. Uses a heated muffle with proportionally controlled electric heating or natural-gas combustion. Multiple independently controlled zones provide uniform temperature profiles along the furnace length. Lower capital cost and reduced maintenance compared with alternative CAB methods.
• Convection/Radiation CAB Furnace: Combines convection preheating with radiation brazing to handle parts of varying mass and dimensions within the same cycle. The initial zone uses convection and radiation for uniform preheat; the radiation section achieves and holds final temperature for proper clad melt and joint formation. Medium capital cost and faster throughput in a compact footprint.
• Full Convection CAB Furnace: Pure convection controlled-atmosphere furnace that processes the widest variety of parts with the shortest cycle times. Recirculated nitrogen atmosphere and forced convection deliver uniformity to ±3 °C. Compact footprint for equivalent production and effective for mixed-size loads and large heat exchangers.

Green electromobility and design features

• Supports brazing of components for electric vehicles.
• Reduces emissions through efficient atmosphere management.
