EVAPORATION TECHNOLOGY

It is understood that water can be present in oil due to several factors.  It is also understood that the heat of the equipment will evaporate a portion of the water, but not to the extent needed to protect the equipment as there is a large volume of oil relative to the heated surface area of the equipment.

  • The Micron Finer system engenders the opposite effect with the heated diffuser plate - i.e. a Micron Eagle EOLSsmall volume of oil relative to the heated surface area. This is known as the "thin film evaporation effect" and is critical to the performance of the Micron Finer system in removing and preventing the formation of harmful contaminants.  In the filtration technology page, we discuss the effect of the cotton filter in the Micron Finer system in addressing acid contamination, however, it would obviously be of greater benefit to oil conditioning (in terms of maintaining alkali additive levels and the fundamental ability of the oil to flow and shear) if acid build up was prevented in the first place.  This can be achieved by the Micron Finer system due to the evaporation chamber - water and sulphur dioxide/trioxide will still pass through the filter and flow over the diffuser plate. At this point, the thin film evaporation effect will allow the release of both liquid contaminant (water) and gaseous contaminant (SO). Liquid and gases are evaporated by the same process, preventing the formation of sulphuric acid; the same will also apply to nitric or other acids that might be formed.  In general terms: -prevention is butter than a cure.

  • Due to this effect, alkali additive in oil - calcium and magnesium - will not be depleted and condition of the oil will remain stable.

  • Aluminum is the material used in the evaporation chamber due to its ability to quickly and uniformly radiate heat generated by the heating element. Note: the Micron Finer system will not add heat to the equipment. Test have proven that fluid entering the system at 122° F (50° C) will exit at the same temperature; on engine applications a slight cooling effect (+/- 0.05°) is noticed.
