Coolants

How to properly mix a coolant?

The ratio or concentration for each operation is different.  Consult with your Tower Sales Engineer on the target ratio.  Once this is established, use the "O.I.L." method.  " Oil in Last"  This applies to soluble oils, semi-synthetics, and synthetic water extendable products.  

For example - if your target ratio is 9:1 or 10%, add 9 parts of water to your container.  Then begin to add one part lubricant concentrate with agitation to get proper mixing.

Using a refractometer, get a reading from the mixed solution.  Every product has a different factor to determine the correct refractometer reading.  

The formula for this calculation is: Refractometer Reading (RI) = Concentration % / Factor.

For Tower's Saf-T-Cool 458, the Factor is 2.2.  So for a 9:1 or 10% solution, the Refractometer Reading is:

10% / 2.2 = 4.5

If your reading is higher, then you have too much coolant concentrate in your container.  If your reading is lower, then you have too much water.

There are a number of mechanical ways to properly mix coolants as well.  Please give us a call, and we will have one of our trained Application Engineers contact you to determine which method is best for your operations.
