DSG – Defrost Spray Gun


The DSG is a high-tech machine used as an ice prevention system on the railway catenary. In fact, ice causes serious problems in the current collection circuits, making traction difficult or, in extreme cases, leading to breakage of the catenary. In the DSG, a gun sprays biodegradable oil on the wire of the catenary, the oil prevents the formation of ice. During spraying, which takes place at the maximum speed of 50 kph, an automatic computerized system (Dipsa patent) constantly keeps the spray gun under the wire, following it in the stagger and up/down movements. DSG, commercially known as "Iceguard", was awarded by DITECFER as the best innovation in the railway field for the year 2020. Contact us for more information or for a customized solution.
