O/T Coolant

[Jim Whipple]

This is slightly off topic but I thought I'd get you guys (and Gal's) opinion

I use ValCool VNT 935 and am happy with it. The Hangsterfers guy was just in yesterday and wants me to give his stuff a try

Any opinions??

Thanks

Jim

Good day,

 

I'm sorry I missed the original post about coolant...But I've spent many years reserching

and using many kinds of oil + water based coolant.

I (for about 2.5 years ) have been using a Castorol Product...yes just like the motor oil.

Its called Alusol AU-39 ,a good all around coolant . All machines I've used them on

never got any smell. And the rule Is always add

coolant not water... not only for seperation ,but

the new coolant recharges the PH level and prevents bacteria ( smell ). This coolant also

has very good tramp oil rejection...and also needs to be skimmed. Most smell and bacteria

problems happen when a coolant is not skimmed

or has poor oil rejection. I've found that running coolant pump even when machine is not cutting metal keeps coolant ph high and introduces air and motion into fluid which keeps bacteria down. Generaly a coolants ph right out of the drum,properly mixed should be 9.0 to 9.5.

Bacteria and smell start when coolant sits and/or

the ph drops to or near 7.0 .

Excellent, we now have some values that are tangable, we can use a PH test as part of the maintainence plan to keep from throwing away good coolant. PH 9=Good PH=7 Bad (Either needs help, or to be removed...)

The Blaso rep showed me how to use the

Test strips,And that my water is Really hard.

He also showed me that you have to set

Your refractometer to "0" with the water your going to mix the coolant with.

THEN mix it to 8%
