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

After winning a hard international tender. Sea Marconi developed and built two plants for the physical decontamination under vacuum of mineral insulating oils, procured by Compagnie Ivoirienne de l’électricité (CIE), the company involved with the transportation of electric power in the Ivory Coast (North-Western Africa). The test of the plants and the training of the Ivorian operators took place from 3rd through 5thOctober 2011Read more

The satisfactory conclusion of the training of the Korean engineers, the timly delivery terms and the performance of the plant during the final tests, emphasize, once more, Sea Marconi’s leadership on the topic of decontamination of PCBs on a worldwide scale. But we make a step backward. The interest shown by the Korean company GreenField Ltd at the end of 2008, tookRead more

Sea Marconi is confirmed again as a leader in services and technologies destined toward the treatment of dielectric fluids (insulating oil). A few days ago, in fact, the installation of a new system for the treatment of mineral insulating oils in operation has been completed in South Africa. The system has been developed and manufactured by Sea Marconi answering theRead more
