Varnish is a type of harmful contamination which adheres to metal surfaces and can cause hot spots, an increase in machine temperature, filter plugging and micro-dieseling.

Varnish, a result of oxidation, occurs in components like turbines, compressors, hydraulics, large circulation and lube systems. If not caught early, varnish can cause serious system damage leaving you with unplanned downtime, maintenance problems and even failure.

Topics include:

• Cycle of the oxidation process of a lubricant causing varnish
• Visual examples of identified varnish formations
• I-MPC vs. S-MPC test methods, correlations and results
• Consequences and results of not addressing varnish
• Recommended filtration and removal methods
• How to prevent varnish from forming
