Improvements in filter media efficiency coupled with higher flow rates and more resistive Group II oils has brought filter element spark discharge to the forefront in many power plants. A common reaction to sparking has been a migration to coarser filter media selections (i.e. 25~40 micron nominal) to try to minimize the occurrence of sparking. Although sparking might be reduced with such choices fluid cleanliness and bearing surfaces suffer as [ISO Codes](https://www.hyprofiltration.com/industry-applications/power-generation-hydro/knowledge/detail/general/iso-fluid-cleanliness-code-understanding-what-is-it-iso-code/?hsLang=en) trend higher over time.

However, when properly maintained phosphate ester fluids not only provide the safety of fire resistance and years of reliable EHC system operation free of contamination related servo valve failures and indefinite fluid life. Hy-Pro has the full solution for phosphate ester to properly manage and eliminate problems with acid production, water contamination, dissolved metals, sub-micron products of thermal degradation, dark fluid, sludge and deposits and particulate contamination.
