For mass-production manufacturers of automotive radiators, oil coolers, and condenser cores, maintaining absolute atmospheric purity during continuous assembly is vital. Our Continuous Controlled Atmosphere Aluminum Brazing Furnace (commonly known as a CAB furnace) utilizes a high-purity nitrogen envelope with a non-corrosive flux to produce clean, high-strength, leak-free joints without post-braze acid washing. One of our key clients in the HVAC industry reported a major reduction in their product leak rate-down to virtually zero-after integrating our continuous belt-driven Continuous Controlled Atmosphere Aluminum Brazing Furnace into their automated assembly line.
As a direct manufacturing factory established in 2002, we have optimized this Continuous Controlled Atmosphere Aluminum Brazing Furnace to maintain an oxygen-free nitrogen atmosphere with an oxygen level consistently below 10-15 ppm. This is achieved through our precision-engineered entrance purge chambers and air curtain designs. The furnace muffle is constructed from premium heat-resistant alloys to prevent high-temperature distortion over years of continuous operation. Leveraging our deep experience as a supplier to industry giants like BYD, we design these continuous lines to minimize nitrogen consumption, cutting your operational utility costs while maintaining the consistent thermal profile required for premium heat exchanger brazing.

Application Fields
Automotive Heat Exchangers
Continuous brazing of aluminum radiators, condensers, evaporators, and heater cores.
Industrial Cooling Systems
Production of plate-fin oil coolers, charge air coolers, and heavy-duty generators.
HVAC Systems
High-volume brazing of residential and commercial air conditioning heat exchangers.
Our Factory Strength
Operating out of our 10,000-square-meter facility in Foshan, China, we have designed and built more than 1,000 industrial furnace installations worldwide. Our 70+ workforce includes 6 dedicated, highly experienced thermal R&D engineers who continuously innovate to improve energy efficiency. Our proven track record of working with leading national and global brands demonstrates our reliability in delivering robust, high-throughput thermal machinery.
Quality Control Protocols
Our quality control processes conform strictly to ISO9001 standards. Each continuous furnace line is fully assembled, dry-tested, and thermally profiled at our facility before shipping to ensure exact temperature distribution across the entire belt width. We perform rigorous structural leak testing on the muffle and atmosphere chambers to ensure oxygen ingress is prevented, and we welcome third-party inspections to verify all critical performance metrics.
Packaging & Heavy Shipping
Due to the substantial length of continuous brazing lines, we divide the equipment into modular, transportable sections. Each section is heavily braced, wrapped in industrial-grade moisture-barrier plastic, and secured inside robust steel-reinforced wooden frames. Sensitive PLC electrical cabinets and control valves are packed in customized waterproof crates with heavy desiccants to prevent corrosion during ocean transit.
