Degradation 6C – Varnish Removal

Varnish buildup in lubrication systems is a significant challenge in industrial operations, leading to restricted oil flow, sticking valves, increased friction, and premature equipment failure. This course provides a comprehensive approach to understanding varnish formation, detection, and removal methods to restore and maintain optimal lubrication system performance.

Participants will explore the different types of varnish, the effectiveness of various removal techniques, and how to select the appropriate method based on system requirements and severity of contamination. The course also covers chemical and mechanical removal techniques, including depth media filtration, centrifuging, electrostatic separation, balanced charge agglomeration, resin media filtration, detergents, solubility enhancers, and system flushing.

Designed for maintenance professionals, reliability engineers, and lubrication specialists, this course equips participants with practical knowledge and tools to effectively diagnose and mitigate varnish-related issues, extending the life of both lubricants and machinery.
