Straight Talk On Varnish…Read the Full Conference Paper

Mineral oil-derived base stocks are the most prevalent lubricant in turbine applications; however, synthetics are also starting to be used. PAGs have been positioned as varnish-free alternatives to conventional mineral turbine oils. Our findings suggest that a quality Group II lubricant out performs the PAG in oxidative tests. This result is somewhat unexpected and suggests that moving from a low cost, low quality Group II to PAG is an overreaction, when better performing Group II oils are available at a much lower cost.

Turbine Lubricant Varnish White Paper

Lubricant varnish production is a problem that will affect most rotating equipment at some point in its normal service lifetime, leading to production losses. Varnish begins its life as a dissolved degradation product before converting to particulate form and depositing on metal surfaces. Most approaches in the market place do not address this root cause.

Learn more about the cause of lubricant varnishing and strategies to solve it by downloading our recent varnish white paper.

Next Steps

EPT’s 4-step program provides guaranteed results and offers a predictable cost to operate year-over-year that is less than the cost of two drums of PAG.


Step 1: Complimentary Expert Assessment (ACE™ Plus)

Samples are tested, cleaned with EPT’s SVR™ system and re-tested with a comprehensive report.


Step 2: SVR™ System

Our soluble varnish removal (SVR™) system targets and eliminates the primary cause of varnish formation – dissolved oxidation breakdown products.

Step 3: NSD™ Filters

Our Non-Spark Discharge (NSD™) filters suppress filter sparking by significantly reducing friction. This eliminates the related high-temperature fluid breakdown protecting antioxidants and base oil.


Step 4: Results Verification

Complimentary Expert Assessment repeated until results are documented and user is satisfied.
