描述
When varnish forms in combustion turbine lubrication and control systems, the effects can be devastating. Significant varnish build-up leads to:
- Sluggish control and/or equipment reliability issues
- Unscheduled maintenance operations/excessive parts
replacement - Problematic start-ups and/or shut-downs
- Forced equipment outages and lost production tim
As the leader in gas turbine lubrication and hydraulic fluid control, Pall introduces a very efficient, simple, and proven varnish removal system. Pall VRF (Varnish Removal Filter) will dramatically reduce the varnish potential of the fluid, ensuring long, healthy operation, and control of gas turbines.
Features
- Conforms to the ANSI B31.1 - Power Piping Code and the ANSI B31.3 - Process Piping Code
- Varnish removal vessel with specially designed adsorptive media, optimized for removal of varnish-forming precursors from the oil
- Outlet filtration with Pall Ultipleat® SRT technology, antistatic and rated at ß12(c) >1000 for additional protection and cleanliness
- Control system designed to maintain optimum oil temperature for the most efficient removal of varnish
- Simple, reliable operation requiring minimal operator attention
Applications
Applications

Performance
Performance
Field experience with Pall VRF on gas turbines showed a rapid and stable reduction in varnish potential rating (VPRSM)1 well below the recommended levels. Pall VRF will maintain low varnish potential as the entire system gets cleaned up over time, literally pulling varnish off surfaces for removal. A turbine can be rid of varnish issues in a matter of a few weeks. The combination of Pall SRT filter technology to control varnish formation and the Pall VRF to remove existing varnish will ensure elimination of varnish-related problems.
