The Hangsterfer's coolants are just not that good and they keep raising the prices !! The s-500 is loaded with phenols and that will cause big problems with waste treatment and cause the seals to swell

If the tank level gets too low the pump will thrash the coolant and essentially "spray foam". This is very simple, and many times the cause for excessive foam.
Obviously, if the chip tray gets too full and coolant is foamy it will overflow the basket. My machines used to overflow all day long, until I got a new operator who actually checks and empties the chip trays. They never overflow nowadays.
I find that the chips created by serrated roughing bits tend to clog the tray. With this in mind, empty the tray sooner.
If I don't need a full blast of coolant I throttle it back. For example I run my coolant at about 1/2 the pressure (the valve at the nozzles) when I am cutting steel with TIALN coated carbide bits.
Let your chips dam up the two downhill runs into the chip tray. Add a damn there if needed. If your coolant is foaming, "filtering" it through chips before it hits the chip tray is very helpful to reduce foam. Chips pop air bubbles.
I run my S500 at 5%-10% concentration. It foams alot when fresh. I deal with it though... it lasts me 3-4 months longer than anything else I have ever used (before it rots like a dead body)
