10 Wa t e r C o n t e n t Water absorbing capacities of different fluid types The water absorbing capacity varies from oil to oil. At saturation point (>100 % Relative humidity) free water will cause the fluid to have a cloudy appearance. Mineral oil containing Synthetic ester containing 500 ppm H2O 500 ppm H2O ppm = parts per million, 500 ppm = 0,5 l water in 1000 l oil 10,000 ppm 1% 1,000 ppm 0.1% 100 ppm 0.01% ppm H2O 2500 2000 1500 1000 500 0 Mineral oil Synthetic ester

An installed moisture sensor gives early warning, permitting fast action to extend the oil lifetime and machine availability. 11 Consequences of water contamination Negative influence on: • Capacity of air separation • Antifoams • Lubrication performance Accelerated oil oxidation Degeneration of additives Accelerates: • Corrosion • Wear Shortened oil lifetime System failure

ISO 4406:1999 is a 3 digit code, representing the cumulative counts per ml at 4, 6 and 14 ì m(c). The counts at each size are compared with the table to find the contamination code. The code is written as 3 numbers separated by a '/'. For example: 19/17/14. The first number represents the count at 4 ì m(c ), the second at 6 ì m(c ) and the third at 14 ì m(c ). More details can be found in ISO Standard 4406:1999.
