Field Results - CNC Coolant Filtration

CNC Coolant Filtration Progression Clean & Clear's OSD™ technology removes contaminants from CNC coolant without chemical change to the coolant. With fully filtered coolant on the left and unfiltered coolant on the right, this photo shows the progression of CNC coolant through various stages of the the Clean & Clear OSD™ filtration process (the middle two bottles show coolant after partial filtration).

Below are descriptions of two field tests conducted of Clean & Clear's OSD™ technology in CNC Coolant Filtration applications. The first test shown was done on the Clean & Clear OSD™ installation at Suburban Manufacturing; the second test shown was done on the Clean & Clear OSD™ installation at Waterous Company.

Suburban Manufacturing

Background. Suburban Manufacturing is a recognized leader in heating and water heating equipment for the recreational vehicle industry. It also offers products to the residential and commercial markets. Suburban installed Clean & Clear OSD™ CNC Coolant Filtration System to remove contaminants from their CNC coolant, thus making the coolant suitable for reuse.

Results. Independent tests of Suburban's Clean & Clear OSD™ system were performed by Hangsterfer's Laboratories, Inc. The results of Hangsterfer's before and after testing of Suburban's CNC Coolant are shown below:

Test	Sample - BEFORE Filtration	Sample - AFTER Filtration
Lab Report Number	020122	020123
Description	Non-Filtered Used Coolant	Filtrated Used Coolant
Refractometer Shaken Decanted	Cloudy - 8 Cloudy - 8	Cloudy - 7 Cloudy - 7
Appearance	Milky	Milky
Odor	Mild	Mild
Foam	High	High
pH	8.9	8.9
Tramp Oil percent by volume	3	Ring
Cream Layer percent by volume	Ring	1
Solids percent by volume	Trace	Trace
Acid Split (Tramp Oil + Coolant) percent by volume	12.8	7.2
Actual Coolant Concentration percent by volume	9.8	6.7
Total Dissolved Solids milligrams/liter	3240	1610
Conductivity microseimens	4880	2420

Fungus	Nil	Nil
Samples
Comments	Conclusion: This sample is in fair condition. The concentration and pH are good. There is too much tramp oil. Conductivity and TDS are relatively high, suggesting contamination. Recommendation: Remove the tramp oil. Continue with proper maintenance.	Conclusion: This sample is in good condition. The concentration and pH are good. Recommendation: Continue with proper maintenance.
