The Tech Inc. Fire-Resistant (EH) Oil Purification Unit keeps the phosphate-ester fire-resistant fluid in steam turbine electro-hydraulic (EH) control systems within limits. It removes acid, water and fine particles, which are the causes of servo valve sticking, varnish and fluid replacement. It runs in a kidney loop on the EH reservoir while the turbine is in service.
Main components
- Circulation pump with motor
- Acid-removal vessels with ion-exchange resin or activated alumina media
- Vacuum dehydration stage to remove dissolved and free water
- Fine filter housings for particle removal
- Heater, pressure and temperature instruments, and sample points
- Control panel and drip tray on a compact skid or trolley
Applications: steam turbine EH control systems in thermal, nuclear and combined-cycle power plants, and other fire-resistant hydraulic systems.
