Identify Varnish Potential and Avoid Unexpected Downtime The lubricating oil in gas turbines and hydraulic systems is increasingly subject to the ravages of varnish.  The debilitating effects of varnish are well documented.  The complexities associated with detecting varnish potential render routine oil analysis ineffective in reporting varnish. However, there are a number of technologies, although…

Measuring Varnish Potential in Lube Oil Lubricating oil in gas turbines and hydraulic systems is unfortunately subject to the ravages of varnish. It is well-documented that varnish is an insoluble contaminant comprised of oil degradation by-products and sometimes depleted additive molecules. It is generally caused by some type of thermal (heat-related) stress placed on the…
