Year Founded:

Sea Marconi was established in Turin in 1968 based on a business concept by Vander Tumiatti. The company now operates in the key sectors of energy and the environment, with sustainable solutions for the management of transformers and other electrical equipment filled with insulating fluids (core business).

Over the years the company has become a trusted partner to major industrial groups and utilities in the field of energy production, transmission and distribution. Our clients include: Terna, Gruppo EDF Italia, GDS Italia, Eni, Enipower, Edipower, Enel in Italia; EDF, ERDF, RTE, Rio Tinto Alcan, SNCF, Total and Arkema in France; ADIF, Endesa e Repsol in Spain and many other players on the international arena.

These treatments prevent the change of the oil, thus provide a financial advantage to the owner and an enormous benefit for the environment. 3 - Decontamination of oils with PCBs (dehalogenation), called CDP Process, complying with the obligations prescribed by European and International Directives. Thanks to this solution, it is possible to prevent the disposal of the oil and the transformer. In 2007, the Italian Ministry of the Environment officially certified the CDP Process® as the most effective system for the decontamination of transformers in operation and at the end of life.

The treatments just described are performed on-site using decontamination mobile units (DMU) developed and built internally.

Today, Sea Marconi operates in about 50 Countries servicing more than 3000 Customers in different market sectors, including: energy, industries, services, defense.
