Is this an aqueous wash or chemistry wash? If aqueous you will need a DI water system at your facility. There are several ways of going about that, but there is an initial capital investment. Good luck on your project.....

It'll be a DI system. As it turns out, we contacted another EMS company down here, and asked them what they did. They pointed us to their supplier. Conveniently, the same company will set up the DI system for us, and the post wash filtering/plum

Thanks, Dave. As a start-up, we're trying to make it as cost effective as possible. That said, we also want to do it right. We don't want the possibility of the City/State/EPA coming down on us anytime in the future for contaminants being discharg

We've just acquired a batch washer at an auction, and want to install it as a closed loop system. The only problem is I have no idea where to turn or what to look for for a drain filtering system that will allow us to make it a closed loop system.

Approaches to getting started are: * Most batch cleaning equipment suppliers provide both open and closed loop options on their machines. Talk to them about upgrading your machine. * There are companies that specialize in supplying closed loop system

We used to have a Nuclean 324 that was running closed loop with a DI water recirc system. We also had problems with foaming that was solved with a relatively simple fix. We bypassed the final rinse solenoid so that it was always running. This allo

Brian, We've see foaming issues with our wave flux occasionally when running large slugs of product through the wash. We love the wave flux and changing it was not an option. Our process parameters for the wash machine we're derived via a validati

| We're a CM doing low volume/high mix and are considering buying from one of the two big names, TR** or Sp*******/El*********. We need saponified wash for some of our no-clean over wave; the great majority is OA from our SMT lines. Any thoughts? |

Cleaning film build-up in a Stainless wash system....

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

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
