A byproduct of oil degradation over time, varnish is a nasty coating that sticks to surfaces, decreasing equipment performance, and increasing downtime. And while flushing can remove some of the residue, it’s not enough to completely eliminate varnish.
Clean and Control
Waiting to react to varnish after it’s causing problems isn’t enough to solve them. It takes two steps: reliable cleaning, and a lubricant that’s specially designed to prevent varnish formation in the first place.
Varnish is no longer beyond your control
Many reliability engineers see varnish buildup as just a way of life in turbine
lubrication. Varnish created by lubricant oxidation and degradation is a
major concern for power generation companies. Varnish can cause gas regulation
valves to stick and impair oil cooler performance, resulting in serious
operational issues or, in the worst case, an automatic shutdown or failure to start.
- Varnish over time can cause a derating of performance
- Inability to provide on time power
- Impact financial success and safe operations

The VARTECH® Solution
Step 1 - CLEAN
System Cleaner (ISC)
VARTECH® Industrial System Cleaner (ISC) cleans existing varnish and prepares the system for fresh oil – all while your operation remains online – and works quickly and efficiently to help you restore your equipment to peak performance for outstanding reliability and productivity.
Step 2 - CONTROL
GST Advantage® RO with
GST Advantage® RO with VARTECH® Technology limits varnish precursors, preventing varnish from forming and helps maintain peak performance, reliability and productivity in your non-geared gas and steam turbines. Also available as ISOCLEAN® Certified Lubricants.
GST Advantage® EP with
GST Advantage® EP with VARTECH® Technology limits varnish precursors, preventing varnish from forming and has outstanding thermal and oxidation stability which allows it to withstand high temperatures found in turbine bearing and gear lubrications. Also available as ISOCLEAN® Certified Lubricants.
Many reliability engineers see varnish buildup as just a way of life that can only be addressed after operating problems occur. But the cost of waiting to fix that problem is more than you’d think, because the related hidden costs can add up before you even realize you have a varnish problem in the first place.
Do you have a Management of Change (MOC) policy?
You need a partner who understands your policies for the management of change. We respect that process and want to ensure a smooth transition for your operation.
