As the oil heats and cools in cycles throughout a mechanical system, it begins to degrade. When this happens, impurities develop that begin to stick to internal components. Most people refer to these impurities as sludge or tar.
If the varnish isn’t removed, it builds up in valves, pumps, and other internal components causing them to be less efficient. It also causes the oil flow at a higher temperature than it should, which leads to even more varnish. This decreases oil life while also increasing the risk of unplanned outages.
Total operating costs to run equipment with varnish build-up are higher and overall system reliability is lower. It’s best to implement a regular process for monitoring your system for varnish, identifying its causes in your system, and eliminating sludge before it becomes an expensive problem.
Depending on the oil and additives you use, the process to remove varnish is unique to every system. It requires experts to analyze your oil and study your system to determine the most effective course of action. However, most issues can be resolved without taking the system offline. More often than not, the additive mix just needs to be adjusted to reduce build-up, but sometimes some additional filtering equipment is required.
After implementing a solution, our team will verify its results and continue to keep your machinery operating at peak performance.
Once your system has varnish issues under control, you’ll notice that filter changes will be less frequent and your lubricant life will substantially increase. Varnish mitigation also does not affect the additive package used in oils or oil life. It’s a net benefit to your system, increasing its reliability and extending the life of its components.
