New Coolant Trials

If testing a coolant for the first time, it is best to test it on a few individual sump systems, rather than on a centralized one. Any adverse or negative qualities can then be accessed without damaging all your parts or equipment.

Remember, a decent grade of MWF will perform its function, so evaluate the new coolant and track data for these recommended evaluation items in order of their importance for your operations:

  • Stability in mixture
  • Tool Life/Lubricity
  • Biological Control
  • Rust Prevention
  • Filterability
  • Foam Prevention
  • Residues
  • Prevents odors
  • Compatable with equipment paint and coatings
  • No adverse health effects

Length of the test should also be considered. A coolant will not necessarily perform as well 3-6 months after its initial charge as it did during the first three months. A trial lasting 3 months will give a good indication of how that coolant will perform overall in your operations, given proper maintenance.
