EPT - Model ICB FRF -Ion-Exchange Filter for Phosphate Ester Fluid
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.
ICB® FRF, patented ion-exchange technology, is designed to address phosphate ester chemistry, removing acids, phenols and varnish while simultaneously improving resistivity. More importantly, ICB FRF removes varnish precursors responsible for the primary mechanical failure pathways in EHC systems. With 30 years of proven results, ICB FRF is an engineered workhorse designed to address phosphate ester fluid chemistry, preventing EHC failures and saving end-users hundreds of thousands of dollars in costly fluid replacement and system flushing.
