Decsa was contacted by a company based in Marghera, specialised in the recovery and preparation of recyclable waste, for the revamping of four existing cooling towers.<\/h2>\n\n\n\n

Introduction<\/h2>\n\n\n\n

Ensuring the long-term reliability and efficiency of industrial cooling systems is essential for companies operating in demanding production environments. Through targeted revamping projects, existing cooling towers can be upgraded, extending their service life while improving performance, efficiency, and operational reliability.<\/em><\/p>\n\n\n\n

This case study describes the revamping of four Decsa fibreglass evaporative cooling towers installed in 1991 at an industrial waste recovery facility in Marghera (VE), Italy. Thanks to a comprehensive modernisation project, the units were upgraded with new components and an improved water distribution system, allowing the Customer to continue using the existing cooling towers while enhancing their overall efficiency and reducing the risk of corrosion-related issues.<\/em><\/p>\n<\/div>\n\n

\u200dThe Customer’s Problem<\/h2>\n\n\n\n

In July 2023, we were contacted by a long-standing customer specialised in solid waste recovery to carry out an inspection of four Decsa (Cofinair) fibreglass evaporative cooling towers installed in Marghera, Venice, Italy, in 1991.<\/p>\n\n\n\n

Following a thorough analysis performed by Decsa\u2019s Service technicians, it emerged that the units, although outdated, were still operational but required a major modernisation intervention (revamping).<\/p>\n<\/div>\n\n

The solution: cooling tower revamping<\/h2>\n\n\n\n

In agreement with the Customer \u2014 who did not want to replace the evaporative cooling towers but preferred to carry out maintenance work on the existing units \u2014 Decsa proposed an almost complete revamping<\/a> of the cooling towers (with the exception of the motors, fans, and the upper fibreglass cover).<\/p>\n\n\n\n
