My parts washer keeps foaming over... Why?

Foam is the result of too much pressure aerating the mass of liquid. However, in order to correctly troubleshoot the problem, we need to understand some variables about your specific cleaning process.

Most foam is controlled with the use of temperature or de-foaming agents. However in some applications, the actual soil that is being removed (i.e. coolants, lubricants) enter the wash bath and creates a frothy soap. When a high enough concentration of this builds up, the only thing left to do is dump the tank.

Most cleaning chemistries or soaps require an operational temperature of at least 120 degrees or they will foam. If your solution temperature is less than 120 degrees, try to raise the temperature to at least 140 and see if this addresses the problem. Another contributing factor, as mentioned earlier, could be because a low-foam chemistry or soap that is designed for the specific application is not being used.

JRI has developed new low-temperature and low foam chemistries to help these sorts of situations. If you would like to operate your machine at a lower temperature and reduce your soap "dependency", contact us and see how we can help!


Why do my heat elements keep blowing?

Many times, gunk (the stuff you are cleaning off) will build up on the heating elements creating a blanket of insulation on the elements. This build-up causes the elements to have to work harder to maintain temperature in the tank, and this can lead to element failures.

The best way to maintain a long service life for the heat elements is to implement a regular service interval that will include a gentle cleaning of the tanks as well as the elements. Just regularly wiping them down can help significantly.


Is stainless steel construction really worth the extra cost?

This is a question that is best answered by you! How long do you plan on keeping the system? Stainless steel construction can provide you with a system that will structurally last forever. Normal wear and tear items will of course need to be replaced over time.

Many washer suppliers will try to "scare" you into thinking that you have to buy stainless steel, or the machine will fall apart in just a few years. This is only the case if you operate your machine improperly. So what's the proper way to run a parts washer?

First and foremost, it's important to use a quality cleaning chemistry that has a robust inhibitor package built into it. Even at 1-2% concentration, this will be enough to properly inhibit the mild steel structure. Second, run it! The worst thing that you can do is let a mild machine "sit and cook" all day without water circulating. Rust does not occur under solution, it occurs above the solution.

Third, if you are using a caustic, acidic, or corrosive cleaner, mild steel will never stand a chance. You must buy stainless steel options, and we recommend our SS2 package with 99% stainless steel construction!
