Constant changes in oil temperature cause condensation. The effect of water on oxidation in the oil, however, is dramatic especially in presence of catalysts like copper (CU) or iron (FE):

Sample Water Copper Time T.A.N.
1 no no +3500 hrs 0,17
2 yes yes 400 hrs 11,20

The longer oxidation continues, the higher the acidity level (T.A.N.) of the oil. When the acidity level reaches 2,00 mg KOH/gr, an oil change will be required in order to prevent damage to the equipment.

Water can reduce the life of hydraulic machinery by more than 50%

Tolerances in the modern machinery are usually so small that moving parts alternately produce pressure and vacuum . In a vacuum, moisture will expand considerably (70ºC up to 1/5000) and will cause explosions against the surface areas of the parts.

This, in turn, will produce new wear particles, and surface areas will lose their coating of lubricant as a result. Water attacks metal surfaces ( corrosion ) and will slowly penetrate microscopic pores, thus causing wear by fatigue.

Moisture in the reservoir has the tendency to form rust inside the tank top. Vibrations during the operation of the system will knock the rust particles into the oil, where they are picked up by the pump and distributed throughout the system. New rust particles form where the old ones fell off and the endless contamination cycle continues.

Furthermore, water is the ideal enviroment in which bacteria can multiply, and these will, in turn, break down the additives.


Solid particles

The element set up forces the oil to flow through 114 mm. of filtration material, and to pass through 3 stages of different density. The big particles are retained on top of the element, smaller particles in the 1st. stage, and the smallest particles in the lower compressed part. This progressive removal of particles, results in a high ß-ratio and a very high dirt absorption capacity.





Additionally the cellulose material allows the absorption of up to 200 ml. of water in the filter element. In case of higher water concentrations a special "Water eater" element (WE-100) or a "Water Separation" element (WS-type) can reduce water contamination to less than 100 PPM.



Sludge, resins and oxidation products

The most remarkable and noticeable feature of the Triple R element is his ability to remove resins and oxidation products. The resin removal results from a combination of a special cellulose material with a long flow distance (114 mm.)
through the element.
