Or reduce the amount of flux going into the system. Overspraying or excessive flux drag-out can lead to the foaming. Sometimes if excessive rework is being done with a lot of tacky flux, etc, you will encounter foaming. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Tuesday, May 21, 2013 10:02 AM To: [log in to unmask] Subject: [TN] Another Closed-loop cleaner question... Morning all, I may have already asked this once, and I think I know the answer, but I'll ask anyway. It's not a good idea to use defoamers in a closed-loop cleaner, right? If we're getting too much foam in the wash tank, we should add another carbon bed, correct?
