This build up is likely related to the defoamer. Defoamers are typically based on waxes and/or high molecular weight Hydrocarbons. As defoamers only need to work on the exposed fluid surface, not a lot of defoamer is needed (unless you are using

Is the prewash water going to drain or being re-circulated? If you are re-circulating don't send all or a portion to drain (or your treatment system) even sending a small portion to drain and adding fresh will reduce foaming. You will pull more water

Dear J. Dumont, If the 4512's defoaming package is not active in the distillation process, then you may be dealing with foaming, which is exagerated at boiling point. The 4512's defoaming package may not be carried over in sufficient quantity from

Bill, have you found the problem yet? We have been experiencing the same problem on our H-500C, and have found some clogging in the drain from build up caused by the de-foamer we use. Once cleared, the problem went away.

Please advsie what kind of the solder paste which you are using and we have experience when using Alpha WS609 and found a lot of foaming. Beside, are you using the spray fluxer for your wave or not? If you have spray fluxer then you don't need to u

Run a water-soluble mask that foams in the wash. Use a de-foamer to contol that. One or the other, or both are causing a greasy build-up that is hard to get off in certain areas. I have a closed loop DI water system. Can I use some sort of deterg

We just stepped into the inline wash world with a techical devices new clean galaxy plus. We are noticing a significant amount of foaming when washing our boards after selective solder. One theory is that the water soluble flux used is not being cu

Although water soluble (OA) flux is technically the easiest flux to remove, it is also the most damaging type of flux if not removed. A dishwasher lacks the pressure and nozzle design to produce the very small water particle size required for thorou

Hi All- I've got an old industrial dishwasher converted over to a screen wash. It's a closed system, one screen at a time. Total volume of about 10 gallons, no heater. RoHS solder. This thing is foaming up like a rabid animal. The screens go in

We use an Aqueous Technologies Millennium III closed loop system. The footprint is no more than 12-13 feet. We wash water soluble solder paste residue with excellent results however, due to the nature of our solid solder deposit process, we are washi
