Demulsibility is the ability of oil to separate from water. Oil and water naturally separate because like molecules attract each other. Oil sticks with oil, water sticks with water. Oil is "hydrophobic", or "afraid of water," which is a benefit when it comes to fluids like turbine oil.
All hydraulic and lube systems have a critical contamination tolerance level that is often defined by, but not limited to, the most sensitive system component such as servo valves or high speed journal bearings. Defining the ISO fluid cleanliness code upper limit is a function of component sensitivity, safety, system criticality and ultimately getting the most our of hydraulic and lube assets.
The ISO Cleanliness Code (per ISO4406-1999) is used to quantify particulate contamination levels per milliliter of fluid at 3 sizes - 4µ, 6µ, and 14µ. It is expressed in 3 numbers (example 19/17/14) where each number represents a contaminant level code for the correlating particle size. The code includes all particles of the specified size and larger.
It is important to note that each time a code increases, the quantity range of particles is doubling. Inversely, as a code decreases by one the contaminant level is cut in half.
In this Video we provide a brief description and demonstration of Hy-Pro's signature coalescing technology found in our FCLCOD and COT model lines.
Today's diesel engines require cleaner fuel with injector pressures approaching 30,000 PSI and the evolution of injectors into sophisticated expensive electronic components. Diesel engine manufacturers have learned that ultra-fine particles that were of little consequence at 3,000 PSI are now causing premature failures at 30,000 PSI.
