An oil sample contains a lot of information: let your oil talk!

The analysis of lubricants enables the monitoring of the condition of the mechanical parts and of the hydraulic components, makes it possible to predict the existence of problems generated by wear, and malfunctions.



In this context, the analysis of hydraulic fluids is useful not only to establish the "health condition" of the fluid, but also to understand the conditions under which a plant is operating.
Evaluating the trend of the analytical data over time is a necessary strategy to carry out maintenance operations no longer according to fixed deadlines but according to the actual conditions of the plant. Our technicians, in cooperation with your staff in charge of the use or maintenance of the plants, will be able to advise you in the handling of lubrication, in the planning of maintenance interventions, in assessing your systems and in improving the efficiency of your plants.


To ensure reliable and constant operation of an hydraulic system and its components, the hydraulic fluid must have and maintain over time a degree of contamination from particle material and chemical-physical characteristics within the values established in the designing phase.
The contamination of hydraulic fluids is due to several factors: initial contamination of the new fluid, particles in the environment that can get into the system, deterioration of sealing systems, debris from assembly operations, component wear and condensation. Failure to control the level of contamination of hydraulic fluids can lead to damage and, in the most serious cases, to seizure of the systems. It is clear that quantifying and classifying particulate matter and other pollutants in fluids is a tool to prevent the onset of wear, corrosion and degradation. Our laboratory is equipped with state-of-the-art tools for the characterization of lubricants, we can support you by providing a fluid analysis service with the ability to perform the following tests using standard methods (ASTM, ISO, DIN, ...):
  • Particle counting with an optical microscope (ISO 4407:2002)
  • Classification of the degree of contamination (ISO 4406:1999 - SAE INTERNATIONAL AS4059F - NAS 1638)
  • Gravimetric quantification of particulate matter (ISO 4405:1991)
  • Determination of water contamination with Karl Fischer coulometric titrator (ASTM D6304(C))
  • Determination of wear metals, contaminants and additives (ASTM D6595)
  • T.A.N. Determination - Total Acid Number (ASTM D664)
  • T.B.N. Determination - Total Base Number (ASTM D2896)
  • Colorimetric patch test for varnish precursor evaluation (ASTM D7843)
We also provide a sampling service or instruct customers so that they can proceed with the sampling process in full autonomy.


The market evolves rapidly and requires an increasingly flexible industry, so it is necessary to reduce to a minimum, if not zero, the loss of time and money due to corrective maintenance.
Common sense, observation and experience!
The monitoring of operating conditions allows you to choose the best time to schedule interventions, anticipating failures and using the free time available during production, the most effective and economical maintenance is the one that is done at the right time, carrying out an intervention that ensures the best possible result with the least impact.
“Smart" maintenance based on monitoring through scheduled checks leads to an advantage in terms of cost reduction and an increase in the plant's operational capacity. This also includes the chemical-physical analysis of oils which, based on the residues present in the fluid, identifies which components are deteriorating.
Our technicians trained both through experience on the field and through training courses, can act professionally and are ready to use computer tools for analysis and forecasting, because the objective is to increase the reliability of the plants thanks to predictive maintenance!
An example of a predictive approach in the hydraulic industry
More than 70% of breakdowns in the hydraulic sector are caused by fluid contamination. The contamination of fluids can be liquid (water), gaseous (air) or solid (particulate matter), the latter consisting mainly of oxidized waste, rust and welding debris can be particularly harmful to hydraulic systems. Contamination by solid particles has an abrasive and erosive effect and is responsible for a rapid deterioration of the components. Predictive maintenance, through the monitoring of fluid conditions, allows the timely identification of the need to perform maintenance on the basis of the actual fluid conditions and not on the basis of "projected" anti-oil-dynamic data.


Current hydraulic fluids are more stable and offer greater resistance to oxidative and degenerative phenomena than some time ago, for this reason in many cases, it is possible to "clean" and reuse them.
I see, I predict, I prescribe!
In addition to the analysis service, we offer a treatment service for the restoring of the initial conditions of the oil charges or for the reduction of the initial contamination of particulate matter in new oils, both by operating at the customer's premises, with off-line systems, and by taking the oil charges from the plants and carrying out the treatments at our headquarters in Costa Volpino. All oil treatment services are supported by an analytical file certifying the results obtained.
