TransfoClean is the new “sustainable” solution designed to support owners/holders of electrical transformers withinsulating oils in their complex management activities at all stages of the machine’s life cycle (LCM).
This means primarily damage prevention and environmental protection, and also taking into account budget constraints and regulatory requirements.

TransfoClean is based on the analogy between men-blood and transformer-oil. Similar to the way clinical diagnostics are performed, Sea Marconi monitors the state of health of transformers by analysing (and diagnosing) the oil inside them.

Sustainable solutions for Life Cycle Management (LCM) of electrical equipment with insulating fluids

With the appropriate treatments it is also possible to “cure” particular criticalities and prevent catastrophic failures with possible loss of production and damage to people or the environment.

Sea Marconi is organised into three highly integrated business units:

  • the diagnostics and research laboratory
  • the section that coordinates and carries out on-site services (eg treatments)
  • the engineering section that focuses on construction of systems for the treatment of oils and transformers

Unique elements


of transformer manufacturers, repairers and oil producers

Full technological capability

expertise within the company to design and build our own plants, as well as selling and managing them.

Continuous innovation

in Research and Development, and more than 40 international patents

Compliance with and anticipation of regulations

Sea Marconi employs methods and techniques in conformity with international standards and guidelines (IEC, CENELEC, the Stockholm Convention on PCBs/POPs, etc), and often anticipates them to offer an immediate response to problems not yet covered by regulations

Accredited laboratory (Accredia)

The Sea Marconi laboratory is the only one in Italy accredited for the main analytical tests addressed to determine the state of insulating oils. the accreditation is internationally recognized

Integrated approach

Sea Marconi offers solutions for the protection of both assets (eg. electrical equipment) and the environment (eg. combating PCBs and the treatment and renovation of oil as an alternative to replacing it)
