68-07: Natural Draft Cooling Towers Non Oxidizing Biocides

68-07: Natural Draft Cooling Towers Non Oxidizing BiocidesTo those whose experience with and exposure to cooling towers have been almost exclusively concerned with towers utilizing mechanical draft, those which operate solely by natural means must appear large and clumsy, and perhaps even primitive. However, such is not the case the modern natural draft cooling tower represents a sophisticated design incorporating the ultimate in two areas of technology thermal design and structural design. Ever increasing
