| Coolant foaming problem Hi All, Just wondering if any of you have had a coolant foaming problem. My 2412 seems to constantly overflow in foam. I use a product from MSC called Prime Cut and at the suggested dilution ratio. Any ideas would be most helpful! Thanks Larry |

| I'll tell you my tale of woe about coolant foaming. I have three machines that have high pressure pumps. My Sharp is one of them. I used Valcool 800 and it foamed. I used Hangsterfers S500cf and it foamed like the dickens. I put in all the antifoam crap and that cured the problem for a day. Clogged all the filters with the stuff. I called the Hangsterfers rep and he sent me 10 gal of NeoSol 300 for free. That cured the problem. I spent a lot of time checking PH and hardness of water. Sent in samples to the lab.... Changes to Neosol and the issue went away |

| foaming I dont have a coolant system myself but may add some light with some general knowlenge. One cause for foam or bubbleing is the introduction of air to a liquid. Is it possible your system is taking in air somehow? |

| You will find that alot of brands will foam more then others. We use Blazer in all of our machines and never have a problem. As long as you keep the right dilution its great. We usually try and replace it every 6 months because of the oil, but other then that its a good brand coolant. |

| I use a coolant called liquid ice in mine and as long as I keep the oil in the sump down under a gallon, it is not bad about foaming. I finally ordered a skimmer so I think it will make easier easier. |

| I run two Sharp minis without chip conveyors. I have been using Hangsterfers S500 for about a year now. It foams, but doesn't overflow unless I get lazy. Here's some things I have picked up on: 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) Evan |

| We had our coolant rep in a couple of weeks ago because we had foaming problems, he went over to the machine looked at it a couple of minutes, he then grabbed a pail of our vactra #2 and dumped it in, I about crapped my pants at this!! he said the anti foamers on the market are just oil anyways. The foaming stopped after a couple of hours and we have not had that problem since!! |

| 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

| Uh...... So what would you recomend? Interesting screen name... Are you a salesman? Not very helpfull to knock something with no evidence. Care to quote a couple of sources for "Loaded with phenols" And Wreck havoc with our waste treatment plants? I use Hangsterfers Neosol 300 and have not had any issues with cutting anything nor have I heard anything about environmental issues with ANY of Hangsterfers products. You just piqued my interest with your blanket statement..... |
