An aluminum heat exchanger manufacturer specializing in the production of heat exchangers recently expanded its production capabilities with a semi-continuous furnace for controlled atmosphere brazing (CAB) aluminum components. The system for semi-continuous operation, based on the cycle multi-stage division, is designed to increase the efficiency and quality of the heat exchangers with ribbed plate construction.

SECO/WARWICK provided this CAB system, often chosen by the HVAC industry and manufacturers of car parts, for the industrial production of heat exchangers. The semi-continuous operation mode ensures uniform heating of elements even with above-average dimensions.
“The key advantages of this solution includes higher hourly efficiency — modern brazing technology ensures shorter production cycle time; stable and repeatable quality — the advanced brazing atmosphere control system minimizes the risk of defects, guarantees faster maintenance as well as no production downtime. . . . The semi-continuous CAB system is popular because it allows users to realize a reduction in costs while producing atmosphere brazing with exceptional quality control,” said Piotr Skarbiński, vice president of Aluminum Process and CAB Business Segment in the SECO/WARWICK Group. “We supply solutions to many companies in Asia, and a large part of the contracts are the result of recommendations we receive from our customers.”
The CAB line includes a drying furnace, an inlet purging chamber, a patented heating and brazing chamber, an intermediate cooling chamber with an air jacket and a direct final cooling chamber. The product moves between stages in a horizontal position based on a continuously adjustable cycle time, depending on the load’s type and configuration. The semi-continuous operation mode ensures that even large-sized heat exchangers will be heated evenly during the correct process time.
