A continuous line for controlled atmosphere brazing (CAB) of large-dimension battery coolers will be installed at the plant of a European manufacturer of heat exchangers. This purchase is consistent with continental trends to invest in building supply chains for the manufacture of electric vehicles.

This is the second year in a row that the client is ordering CAB line from SECO/WARWICK, the Polish sister company to SECO/VACUUM in North America; this current commission will be the widest CAB line that the supplier has ever built. Its usable dimensions will allow the customer to manufacture large-dimensioned vehicle battery coolers at a mass scale. The dynamic growth of battery sales involves the growth of sales of other parts such as battery coolers. They are manufactured using highly-specialized continuous lines for controlled atmosphere brazing.

"Globally, we sell more and more CAB lines, which prove well in this industry," said Piotr Skarbiński, vice president of Business Segment Aluminum Process and CAB at SECO/WARWICK. "Our equipment is operated not only in Europe, but also in Asia and North America."

SonFlow is a European manufacturer which has historically been known for manufacturing high-capacity industrial pumps. The company is now expanding into the plate heat exchanger business. Manufacturing state-of-the-art, powerful heat-exchangers has provided the incentive for the plant to purchase a furnace from SECO/WARWICK that will satisfy the current production challenges associated with the brazing process.

The working area of the device (900 x 900 x 1200) will enable the plant to perform in-house brazing, without the need to outsource work to third-parties. Power savings, one of the pillars of their mission, is ensured by the graphite chamber, and the shortened cycle time is guaranteed, thanks to the vacuum level of 10-3 mbar.

"Years of experience," explained Maciej Korecki, VP of the Vacuum Business Segment at SECO/WARWICK Group, "and the above approach have resulted in developing a special design of the cooling nozzles, optimum for brazing companies. This dedicated solution consisting of the special nozzle design for these radiator applications prevents excessive deposits of brazing residues in undesired areas of the heating chamber. With this design, the risk of damaging the device during the brazing process is eliminated."
