Compressors monitoring and diagnostics

Contact Us


For over 85 years SIAD Macchine Impianti has designed and manufactured compressors. SIAD Macchine Impianti offers its customers a complete range of services, with a network of Certified Service Centres over five continents, all managed by qualified engineers.

The experience gained over the years has allowed the Company to create software which is capable of predicting the compressor's behaviour - established from the machine operating data and made available by the instruments installed on it.


Remote compressors monitoring and diagnostics

With this service, all the necessary maintenance can be implemented, without having to resort to costly assembling and disassembling. It is thus possible to reduce costs due to faults by offering more efficient and prompt maintenance, and by increasing the MTBF (Mean Time Between Failures).

Thanks to dedicated maintenance, it is possible to increase the reliability of both the compressor and the systems - and then the life of the components can be forecast with consequent supply benefits from the spare parts warehouse.


Compressors monitoring and diagnostics include:

  • Wear and tear of the crosshead skids
  • Cylinder misalignment
  • Tightening of the rod in the coupling of the piston or crosshead
  • Presence of foreign bodies in the cylinders
  • Excessive valve power losses
  • Gas leaks from the rod sealing pack and piston rings
  • Gas sheaths for delivery and suction valves
  • Valve behaviour (fluttering, excessive spring stiffness, etc.)
  • Suction and delivery pressure pulsation


Compressors monitoring and diagnostics: mechanical analysis

The best maintenance is based on an analysis that takes into account the actual conditions of the compressor and its components.

This compressors monitoring and diagnostic system results in greater reliability thanks to periodic investigation that analyses the machine vibrations and compares these with construction data and process conditions, assessing the trend of the measured data over time.

Periodic compressors monitoring and diagnostics of the effects of the wear and tear on moving mechanical components prevents unexpected problems and improves planning maintenance.

This way, mechanical analysis prevents serious breakdowns and unexpected faults, allowing maintenance only when it is really required and planning routine interventions together with planned plant shutdowns.
