EHC Hydraulic Fluid Testing Offered by Eurofins TestOil

Steam turbines are equipped with electro-hydraulic control (EHC) systems that face unique fluid challenges. Due to these challenges, phosphate ester-based fluids are often used in this application. Phosphate ester fluids are expensive, can be difficult to maintain, and are costly to dispose of.

Because of this, Eurofins TestOil offers a specialized EHC hydraulic fluid analysis for phosphate ester EHC fluids to provide a comprehensive assessment of the fluid condition. Tests that can be included in the analysis are:

Given the cost of replacing this type of fluid and the criticality of the equipment, monthly testing is recommended. Eurofins TestOil Analytical Services Manager Monika Malcolm explains, “If the complete EHC test slate shows the fluid to be healthy, the customer may elect to perform an abbreviated test slate monthly consisting of elemental spectroscopy, viscosity, particle count, acid number, and water content and run the more complete EHC test slate on a six-month interval.” 

Eurofins TestOil’s EHC Fluid Analysis provides the information you need to maintain your phosphate ester EHC fluid and maximize fluid life. View a sample EHC Fluid Analysis Report.
