During the last week in November, Sea Marconi received a delegation coming from the Philippines. The Sea Marconi’s experts have visited the Republic of the Philippines several times (we have already reported in April 2011 the official invitation to Vander Tumiatti as expert in the management and decontamination of electrical equipment with insulating fluids) and thanks to the competency provided, the projectRead more

On 7th November 2012. at the specialised centre organised by the company RADE KONCAR in Skopje (Macedonia), the plant developed by Sea Marconi for the decontamination and recovery of oils and transformer contaminated by PCBs (Polychlorinated biphenyls) has been inaugurated. The project for the “environmental protection through the reduction and the elimination of dangerous substances such as PCBs in the oil of transformers”Read more

A few days ago the fabrication of a plant for Mongolia, finalised toward the dehalogenation of electrical equipment with insulating liquids contaminated by PCBs was completed. This plant is of a DMU (Decontamination Mobile Unit) type with extremely innovative configuration and technical solutions. It is a plant made of two modules designed and developed in a manner allowing the operators to work insideRead more

The tests of the dehalogenation system (removal of PCBs from insulating oil of transformers) destined to Macedonia have been completed positively. Besides the supply of the system, the Sea Marconi’s solution includes a mix of high level products and services for the correct 360° management of the PCBs problem. From one side, the services for transferring the know-how, such educationRead more

Upon the invitation of institutional authorities and local Utilities, on 18th April 2011, Vander Tumiatti travelled to Mongolia as expert in the management of electrical equipment with insulating oils and PCBs. The economy of Mongolia (2.736.800 inhabitants over a surface of 1.565.000 km²) is mainly based on considerable natural resources such as oil, coal and copper. Industry represents currently 21.4 %Read more

Following an invitation by institutional authorities and local Utilities, from 29th March through 1st April 2011, Vander Tumiatti was in the Philippines as an expert in the management of electrical equipment with insulating oils. The archipelago of the Philippines includes over 7,000 islands; the economy has a considerable expansion and for this reason, policies for energy efficiency are required toRead more
