Oil analysis can detect chemical breakdown, water ingression, and particle contamination, monitor the condition of machines without taking them off-line and help optimize your oil usage. Test results can be in-hand hours after the sample is taken or web-based for your review. Oil analysis is a cost-effective way to verify the condition of rotating equipment without stopping your production.

Contamination can be defined as any unwanted substance or energy that enters or contacts the oil. Contaminants can come in a great many forms; some are highly destructive to the oil, its additives, and machine surfaces. Contaminants are often overlooked as a source of failure because its impact is usually slow, but over time, the damage begins eating the machine up from the inside out. While it is not practical to attempt to totally eradicate contamination from in-service lubricants, control of contaminant levels within acceptable limits is accomplishable and vitally important to the health of your machines.

Oil Analysis works great with other predictive technologies especially vibration. If a gearbox, for example, has a vibration issue, using oil to verify that metal is being generated is like pulling another tool out of your pocket to verify the findings of another technology. Using the data from both technologies, you are ensured of doing the right work and not replacing a machine that has no faults!
