  • A Proactive Approach to Treating Varnish Can Prevent Significant Downtime at Plants

    Varnish is one of the most widespread issues in power plants. It’s the hard, oil-insoluble organic residue that cannot be easily removed from mechanical components. It typically occurs in turbines or compressors due to extreme temperatures, disrupting plant operations and causing downtime, which ultimately leads to revenue losses. When varnish forms on a critical piece […]
