About Varnish
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

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.
