Water in oil leads to damagesOil should be clean and dry

EFFECTS OF WATER IN OIL

• Surveys have documented that water or moisture is the second largest contamination (after particles) in oil systems

• Water has a damaging effect on the life time of oil and system components:

• Impaired film strength and lubricity• Corrosion• Hydrogen-induced fractures (embrittlement or blistering)• Fastened oil degradation which will speed up the oils oxidization

Damage to bearing in MAN engine

• The effect is damages to engine parts, cylinders, bearings, etc with resulting mechanical failures and therefore repairs and expensive downtime costs (ranging between EUR 10,000 – 200,000).

• Any oil can hold a certain amount of water (dissolved water) depending on the oil type and temperature – until free water is formed

• Free water is what has the most damaging effects, however, the damaging effect occur already at low water activity. For optimal protection of machine components the water content should not exceed 30% of the saturation point

• The amount of water a specific oil type can dissolve varies significantly, depending on e.g. the base oil, additives, oxidation, temperature and pressure

MEASURING THE WATER ACTIVITY

• Traditionally the water content of oils has been measured using eitherchemicals or laboratory equipment providing a percentage (%) or as ppm(parts per million)

• This laboratory approach has some drawbacks:• The small oil sample may not represent the many tons of oil• Time will elapse before the result returns from the lab – and the damage may actually have

happened before results are knows • The analysis are typically only conducted once or twice a month• Samples are highly dependent on the personnel and correct handling & storage • Many types of oil analysis state water content very inaccurately – e.g. less than 1000 ppm. In many

oil types/applications the damaging effects, however, already occur at 100 ppm• These drawbacks can be eliminated by installing PAJ Water-In-Oil sensors which will monitor the water

level in the entire oil system 24/7.• PAJ sensors have the highest measuring quality in the market, and are calibrated for the specific oil type• The sensor will be giving you early warnings and the ability to take preventing actions – and is thus a

cheap insurance against the very costly repair and downtime costs
