The result is an unmatched trio of physical film. When mixing coolants by hand it is important to always add the concentrate to the water, then agitate. For best results a Hangsterfer's recommended proportioning unit should be used. Never add straight water or concentrate directly to machine. These Hangsterfer's coolants are biostable coolants, designed to control the growth of bacteria.
Regular maintenance is required for maximum performance.
Concentration should be monitored regularly with a calibrated refractometer. Tramp oils should be removed from the coolant surface regularly to prevent unwanted bacterial growth. Keep the coolant system free of cleaners, solvents and other contaminants. All Hangsterfer's soluble oils are designed for easy waste treatment. Hangsterfer's recommends Ultra Filtration or Chemical Treatment for removal of fats, oils, greases and heavy metals prior to disposal of the water phase.
