99-10: The Retrofit of a Big Cooling Tower at an Oil Refinery in Vienna in DriveshaftsAt a big oil refinery in Vienna an 18 unit cooling tower has been retrofitted with fan and drive equipment in combination with a significant noise reduction. Public authorities only allowed the necessary retrofitting of the cooling tower after 18 years of operation, if the dominating noise generation of the towers would be effectively reduced. From an inventory study by acoustic specialists it hs turned out that the cooling tower fans were the
