EPT - Model ICB FRF - Ion-Exchange Filter for Phosphate Ester Fluid - Brochure

Phosphate esters are fire-resistant fluids (FRFs) used in turbine electro-hydraulic control (EHC) systems throughout the power generation industry. Used primarily for their fire-resistant properties and thermal stability, these synthetic fluids hydrolyze and oxidize readily during service, creating harmful acids and phenols. These breakdown products are established varnish precursors that must be removed to ensure reliable servo valve performance in EHC systems.
