CAB Brazing Seminar Recap - Air Cooling Chambers Improve System Performance and Reduce Utility Costs
Modern CAB systems utilize air as the cooling agent in controlled atmosphere cooling sections.
Water cooling systems that were previously used created both corrosion problems and additional cost for external water cooling and pumping systems. Today SECO/WARWICK offers both fast and slow cool chambers, depending on the application.
Fast Cool
The Fast Cool System provides a cooling rate equal to a typical water jacketed system, for instance 600°C down to 250°C in 4 minutes for radiators.

Maintenance Tip: Checking the Braze at the Furnace Exit - Part 5 of 5 Airway Drop
Part was overheated. A row of airways was crushed leaving another row loose. The loose row then falls out. To remedy this situation, you need to run the tracker through. See how much the part is overheated and reduce the temperature or increase the belt speed.
If there are no crushed fins, it is likely that you have a temperature dip somewhere in the furnace. Run the tracker through the furnace. The dip, if there is one, will show up clearly.
The bend radius of the serpentine extrusion might be too large. Fins are loose going into the furnace in localized areas and will drop in these areas.
Fixtures could be bowed. Chick the fixtures with a straight edge or height gauge. Remember that fixtures have a life and should be replaced from time to time.
