Auto Manufacturer Orders CAB Furnace
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.
The Active Only® CAB furnace will allow the manufacturer to braze its own heat exchangers, control quality and manage its production schedules more reliably to improve deliveries to customers.
