• Removal of corrosive sulfurised compounds (DBDS and others)
• Removal of inorganic polar compounds (metals)
• Removal of soluble and insoluble oxidation compounds (acids)
• Removal of insoluble deposits and sludge
• Removal of water in oil and physical contaminants
• Restoration of dielectric properties of oil

and of course the advantages that all treatments using Sea Marconi methodology offer

• Operational safetythrough use of a patented solid reactant, low process temperatures (80-100 °C), no emptying of the transformer and the use of the decontamination unit (MDU) built in-house and equipped with an advanced automatic 24-hours a day monitoring and safety system
• Environmental safety, because Chedcos® avoids the replacement and disposal/transfer and handling of huge amounts of still usable oil, as well as avoids risks associated with the handling of contaminated oil
• The small dimensions of the treatment units allow them to operate even with extreme logistical constraints (e.g . in bunkers, in underground plant quarries)
• Overall cost/benefit ratio
• Functional recovery of oil and transformer(through the unique closed-loop operating mode)
• Normative reference: IEC 60422 Ed. 4 2012 and CENELEC CLC/TR 50503 (02/2010). Reference to Sea Marconi's CDP Process
• Solid application case history with a total of 500items of equipment decontaminated from corrosive sulfur and a total of approx. 7,736tonnes of oil decontaminated from corrosive sulfur (data collected in December 2017)
