Lubricant oxidation results in dissolved breakdown
products accumulating over time pushing
the lubricant towards saturation point.

Once saturation is reached these breakdown
products will deposit on mechanical surfaces.

Sensitive mechanical components
will fail due to tight tolerances.

The EPT SVR™ system eliminates varnish
formation by removing dissolved breakdown
products and preventing saturation.

SVR™ System

Lubricant varnish forms when a lubricant’s capacity to hold dissolved oil breakdown products is exceeded.

EPT’s Soluble Varnish Removal (SVR™) system removes and prevents accumulation of these dissolved oil breakdown products during normal turbine operation so that lubricant varnish cannot form – period.

The SVR™ system targets and eliminates the primary cause of varnish formation; whereas, all other systems (electrostatic, agglomeration, and depth filtration) must wait for varnish to form before they are of any value.

Key Benefits of SVR™ Systems

  • ICB™ filter purification technology for soluble varnish contaminant removal:
    • Over 40 million successful operating hours
    • ICB™ filters will not affect turbine oil additives
    • 4-6x more capacity than competing varnish removal systems
    • Unlike competing systems, SVR™ purifies 100% of reservoir volume each day
  • Quickly reduces and prevents servo valve sticking
  • SVR™ system quickly reduces varnish potential in large gas turbines as measured by the MPC or QSA® (Quantitative Spectrophotometric Analysis – Analysts, Inc.) tests
  • Unlike particulate removal technologies, SVR™ works all the time including operating conditions when varnish is dissolved in the oil
  • Eliminates the varnish formation cycle that typically occurs when the oil cools during turbine shut down
  • Removes all forms of varnish (solid and dissolved)
  • Low cost of ownership over 10 years with defined consumable costs
  • ICB™ filter cartridges are changed annually when installed on common sized reservoirs and used in maintenance mode
  • Small footprint and straight-forward operation
  • Low maintenance: Turn it on and let it run, that’s it!
  • Guaranteed to work with comprehensive analysis included at no charge until results are documented
