Oil analysis, the biggest asset for your systems
All lubricants used or stored break down over time, depending on the type of oil, the usage conditions and the environment.
When the oil deteriorates, its composition and its functional properties change. The degradation process generates a certain number of undesirable products. These can form varnish deposits that will have costly repercussions for the machines as a result of corrosion and stuck valves.

Oil degradation is a common problem that arises both in lubrication systems and on the hydraulics themselves. The main causes are:
- oxidisation
- hydrolysis
- thermal degradation
In many cases, it is a combination of all three. This is why HYD&AU FLUID has developed filtration services and proactively supports its customers to guarantee a longer life for installations.
