Particles and Water in Oil
Where do the particles in the oil come from?
• Built-in - assemply or transport
• Delivered in new oil and fuel
• Generated – from wear and oxidation
• Ingress – from the environment
Where does the water in the oil come from?
• Condensation – temperature changes and humidity
• Ingress – leakage from seals / cooler or accidents
• Delivered in new oil / fuel (MGO etc.)
• Faults in oil handling

Oil Degradation / Oxidation
Degradation products or soft contaminants are a widespread
problem in all industries. They are the precursors of deposit (varnish)
on components causing machine problems.

Oil Degradation / Oxidation
Oil degrades changing its composition and functional properties.
When the oil deteriorates a number of unwanted products are
formed:
• Acid compounds
• Polymerized compounds
(long-chain molecules)
• Sludge (insoluble compounds)
• Varnish (deposit formation)

• Increased component wear
• Reduced machine performance
• Ineffective heat exchangers
• Small tolerances clogging
• Filter blocking and valve sticking
• Restriction of oil flow
Varnish on steering gear
• Increased maintenance resources
