Phosphate Ester Filter, PEU

for Steam Turbine Electro Hydraulic Control Oil Systems (EHC)
 

APPLICATION

The CJC^® Phosphate Ester Filter, PEU is designed to maintain maximum cleanliness of hydraulic fire-resistant fluids (HFD) based on new generation phosphate ester oil (TXP-free) used in high-pressure Steam Turbine Electro Hydraulic Control.

BENEFITS

• Extended oil lifetime and reduced oil waste
• Optimal functioning of servo valves & actuators
• Less wear, extended component lifetime, and lower O&M costs
• Increased reliability, mitigating the risk of turbine trips and failed startups
• Avoiding forced outages and downtime

FEATURES

• Enhanced performance and efficiency
• High decontamination capacity
• Quick & easy installation
• Automatic controls with HMI screen
• Safe and user-friendly operation
• Energy-efficient IE3-motor
• Magnetic coupled pump eliminating leak risk
• Designed for 24/7 operation, +20 years
• Oil sample valve for accurate sampling
• Serviceability-focused design

FUNCTION

The oil is pumped from the bottom of the oil reservoir (drain valve/point) into the first filter stage of the PEU Filter, where the Filter Inserts PEx1 adsorb acidic oil degradation compounds and polar contaminants

Depending on the oil condition, in the second stage, the Filter Inserts PEx2 are used for moisture adsorption or PEx1 or PEx3 for enhanced varnish and particle removal.

Finally, the oil is ultra-fine filtered through the Cellulose Filter Inserts PEx3 to remove submicron particles, including wear particles, soot, insoluble deposits, and sludge.

The PEU Filter utilizes control instruments to ensure reliable and safe operation. A control box with an HMI screen permits easy operation and monitoring of the process and unit condition.
