Varnish Detection through Oil Analysis

Varnish is a type of harmful contamination that adheres to metal surfaces and can cause hot spots, an increase in machine temperature and filter plugging and micro-dieseling. Varnish can occur in turbines, compressors, hydraulics, large circulation and lube systems. It can cause serious, catastrophic damage to your system leaving you with unplanned downtime, maintenance problems and even failure.
