EDGE Coolant Division

Refreshingly Simple!

Too many coolant manufacturers allow their product lines to be overwhelmingly complicated. As they try to squeeze out more and more pennies of margin per gallon of coolant sold, other manufacturers force their customers to stock multiple chemistries in order to produce their parts. But it’s really just a charade. These manufacturers continue to introduce new formulas in an effort to overcome shortcomings in the performance of their existing products.

It’s time to stop the madness and make yourself more competitive by using EDGE Coolants!

Our coolants division product philosophy is simple and straightforward: manufacture the fewest industry-superior chemistries needed to satisfy the broadest scope of customer applications at a competitive price. The result is a limited number of high quality coolants that simplify everyone’s life and saves the end user a lot of money in materials, maintenance, downtime, and disposal fees while improving the quality of life at work at the same time.

Available in 5 gallon pails, 55 gallon drums, and 275 gallon totes.

EDGE Coolant Procedure for Coolant Sump Cleaning

  1. Drain the entire coolant sump
  2. Remove all swarf, chips and other solids
  3. Fill the system with enough water to allow circulation through all lines, filters and tanks
  4. Add the sump cleaner at the recommended concentration, usually 2%-4%.
  5. Circulate the cleaner for 2-8 hours, or longer. If your system is severly contaminated, use the higher concentration and circulate the sump cleaner for as many hours as possible.
  6. Manual scrubbing of some areas may be necessary. Steam cleaning of filters and tanks should be done on large systems, primarily in areas where the cleaner cannot reach.
  7. When completed, drain the cleaner from the system
  8. Refill the system with enough water to circulate through the system to rinse out the cleaner and other residues. If the water is exceptionally dirty, a second rinse may be necessary
  9. Charge the system with the required amount of water
  10. Add the recommended amount of coolant
  11. Circulate the system to assure that the coolant mixes well. In precision grinding, make sure to circulate the fresh charge until it reaches normal operating temperature, so as to avoid size control problems.
