WHITE PAPER:
Water Contamination In Hydraulic & Lubrication Oils, A General Discussion
There are several different types of contamination in hydraulic and lubrication oils which cause problems for reliable operations in industrial plants around the world, including particulate, entrained gases, acids, and varnish. One of the biggest problems is water contamination. Plant maintenance and reliability personnel should pull regular oil samples and have them analyzed for overall water content (as well as other key contamination measurements).
