You know those tall, open topped cylindrical concrete towers you often see pumping white smoke out? Before you freak and worry that these industrial manufacturers are clogging our ozone layer, know this, that white smoke you are seeing is steam being let off from the manufacturing process.
The main job of these towers is to cool down the circulating water that manufacturers use for their processes.
Industrial cooling towers are used to remove heat that is leftover from the manufacturing process. These aeration tower systems were created from the development of 19th century condensers for the steam engines that existed at that time.
