SECO/WARWICK will supply a continuous controlled-atmosphere brazing (CAB) line to an automotive manufacturer’s facility in Slovakia. The CAB line, designed for aluminum brazing, will be used for the mass production of various heat exchangers. It will provide reliability and energy savings while meeting environmental requirements. The furnace will be delivered with a gas heating system, but the design is flexible and can be adapted to fully electric heating. The fully automated solution will allow the manufacturer to increase its overall production and meet the challenges associated with the brazing process.

SECO/WARWICK will deliver a controlled-atmosphere brazing (CAB) line to a global manufacturer of cooling systems for electric-car batteries. This is the second CAB line ordered by the company, which is based in Asia, but it’s the first that will be used for its battery cooling systems. The system will be designed for soldering large battery coolers. CAB technology has been the basic production method for most heat exchangers for passenger cars and other vehicles for several decades. According to SECO/WARWICK, its CAB technology has become the most frequently chosen for soldering battery cooler plates in the hybrid and electric vehicle (EV) industry.

The U.S. department of SECO/WARWICK Group has been selected to relocate a very large controlled-atmosphere brazing (CAB) line for Cold Shot Chillers. The Houston, Texas-based company will use it to conduct in-house furnace brazing of heat exchangers. Built by SECO/WARWICK for another Houston-based OEM in 2005, the CAB line will be the first for Cold Shot Chillers. The Indexing CAB furnace has an overall load size of 48 inches wide x 100 inches long. SECO/WARWICK’s design allows the flexibility to produce a wide variety of sizes and types of heat exchangers on a daily basis. The Indexing solution allows a variety of parts to be brazed with no changes to the menus or furnace settings.

SECO/WARWICK delivered and commissioned what it says is the first-ever vacuum-purging semi-continuous controlled-atmosphere brazing (CAB) furnace for a North American automotive aftermarket manufacturer. It is the company’s first furnace of any type and also its largest capital equipment investment. The furnace, equipped with vacuum purging in the loading and unloading chamber, allows for reduction of nitrogen consumption and cost. It also provides exceptional control of brazing atmosphere quality, which applies particularly to heat exchangers with joints brazed in a closed space. Vacuum purging allows for the removal of oxygen from these spaces before brazing, which cannot be achieved by traditional purging.
