Analysis laboratory

Oil analysis + Diagnosis + Corrective actions

The OilSafe internal oil test laboratory ensures:

  • Timeliness of the maintenance process (average time required to carry out tests: 1 day)

  • Prevention of machine downtime

  • Extension of the life cycle offluids, components and systems

The lab management programmes simplify the entire lubrication control procedure, by monitoring the key parameters of oil basing themselves on international standards, on technical specifications set by the main machinery manufacturers and providing the necessary know-how in order to obtain a better understanding of the status of the lubricants.

Therefore, OilSafe provides an all-round consultancy and analysis service. You take your sample of fluid and OilSafe will analyse it. By means of a technical report, the laboratory staff informs its customers of the results of the tests and, if necessary, any corrective actions and/or maintenance operations to be carried out.

The test laboratory acts provides active support to the OilSafe maintenance operations both during the preliminary plant set-up phases, such as the proper sizing of the flushing circuit and the on-board filters to be adopted, as well as in the subsequent commissioning phase, regarding the monitoring of the conditions of fluids and systems, such as the classification and relative contamination conditions. It is possible to resort to carrying out oil analyses in order to anticipate potential malfunctions and wear, by adopting a predictive maintenance strategy.

Field of application covered by the oil analysis test laboratory include:

  • Predictive maintenance of systems

  • Taking charge of new systems

  • Plant overhaul activities

OilSafe carries out laboratory tests on hydraulic fluids and lubricants, in accordance with national and international methods.
