Specialty Sumpside Additives

Taking side-effects out of the scenario.

Coolant Control offers an extensive line of post-treatment additives designed to eliminate some of the problems that can occur when using in-use metalworking fluids and cleaners—dramatically extending sump life and decreasing total fluid cost. We also offer water treatment products and services to guarantee cleaner, greener, efficient and more profitable systems.



GallonPailDrumToteCuprisan is a unique waste treatable copper complex designed to work synergistically with biocides. When used with an Isothiazolinone-based microbicide, as little as 20% of the normal dosage is required to attain a perfect kill and maintain a controlled fluid. Cuprisan will immediately eliminate and prevent the recurrence of most coolant-borne odors such as the common rotten egg smell. Cuprisan will also aid in the stabilization of water-based cutting fluids.

Cuprisan is typically used at 1 to 2% in metal working fluid concentrates. These concentrates are then further diluted from 10:1 to 40:1 with water.

Added sump side, typically 1/2 to 1 gallon of Cuprisan per 1000 gallons of fluid (20 to 40 ppM Cu+2) is all that is necessary to maintain a stable fluid. When Cuprisan is present in the in-use fluid, as little as 20% of the normal dosage of an Isothiazolinone-based microbicide is sufficient to achieve biological control.

Cuprisan also has applications in water tower treatment or in any application where biological
control is being maintained with an Isothiazolinone-based microbicide.
