WATER States That Water Exists in Oil • Dissolved Water - typically • 100ppm @100°F • 600ppm @140°F • Emulsified – .5% to 4% • Free Water
Sources of Water Contamination • Through system vents • From leaks in coolers and heat exchangers • Precipitation due to a fall in temperature • Introduction of contaminated top-up fluid • Rain in external reservoirs • Rain leaking into incorrectly stowed drums
Effects of WaterContamination • Corrosion of component surfaces • Degradation of fluid performance • Precipitation of additives • Oxidation of hydrocarbon fluids • Deterioration of fluid lubricating properties • Icing at low temperatures • Promotion of microbial growth

ADVANTAGES OF REMOVING WATER FROM OIL • Reduces oxidation, hydrolysis, and subsequent breakdown of the oil. • Acid buildup is eliminated or reduced substantially. • Prevents corrosion of components. • Reduces antifriction bearing wear.
ADVANTAGES OF REMOVING WATER FROM OIL • Reduces pump, valve, and bearing wear. • Reduces rate of filter plugging. • Prevents reduction of oil film strength by dilution with water. • Prevents substantial viscosity changes of the oil.

Bearing Life *Data supplied by Timken Company and refers to tapped roller bearings **Fatigue Life Ratio is determined by testing bearings until half failed A ratio of 1.00 = the test point at which the 50% failure rate is achieved
PARTICULATE • Microscopic Wrecking Crew • Greater Damage Associated With Small Particles • Multiplication Effect “There is no single property of lubricating oil that challenges the reliability of machinery more than suspended particles.” – Jim Fitch of www.OilAnalysis.com
ADVANTAGES OF REMOVING PARTICULATE FROM OIL • Reduces oxidation of oil since silt particles have been found to act as catalysts in accelerating the oxidation process. • Substantially increases life of hydraulic and lubricating system components.
