Mobile off-line fluid cleaning systems

Eaton-IFPM-32-Fluid-Purifier-SystemEaton fluid purifier systems remove free, emulsified and dissolved water, free and dissolved gases, and solid contaminants. They have been developed for different viscosity ranges, from transformer to heavy gear lubricating oils. The selection of the micron rating used depends on the required fluid purity. The mobile fluid cleaning systems in the IFPM series are available in two standard sizes with flow rates of 7.9 gal/min (30 l/min) and 18.5 gal/min (70 l/min).

Effects of water contamination

Water is one of the most frequently occurring contaminants and is second only to particulate contamination as a destructive foreign substance in a system. Some of the problems and damage water contamination can cause include:

  • Shortened service life of the fluid

  • Reduced performance of the lubricating fluid

  • Heavy wear to the components

  • Loss of polarizing additives

  • Rust

  • Increased conductivity

IFPM fluid cleaning system technology

Vacuum evaporation with inert gas is the most effective water removal method for fluid cleaning systems. This method combines high water separation rates with an efficient use of energy, and allows the drying process to take place even below the saturation point of the prepared fluid. By contrast, conventional vacuum evaporation only brings the water content of the fluid to the same level as that of the water vapor in the surrounding atmosphere.

The IFPM fluid purifier systems are fully automated, PLCcontrolled compact enough for use in confined areas. The WSPS 05 sensor permanently monitors the water saturation in a purified fluid. A ventilation filter with silica gel dries the inflowing air, increasing the efficiency of the cleaning system even in environments with high humidity levels. The VS5 electronic contamination sensor provides the optimal use and maintenance scheduling of the particle removal filter element.

Operating principle

  • The contaminated fluid is drawn into the fluid cleaning system using a vacuum

  • The fluid passes a heater, which raises the temperature in order to increase the water removal process

  • Fluid reaches the vacuum chamber through a two-port magnetic valve

  • The dispersion material in the vacuum chamber increases the fluid’s evaporation surface area

  • The vacuum decreases the water evaporation temperature, converting free water and water dissolved in the fluid into steam

  • Ambient air enters through a ventilation filter and passes through the fluid against the direction of flow, acting as a carrier medium for the steam produced

  • The humid air enters a vacuum pump and released into the atmosphere using an oil mist separator
