Concrete body cooling towers are the most tried and tested option in industrial towers. A concrete cooling tower is made of 100% corrosion free material. This is because manufacturers take into account the fact that all other materials have been shown to oxidise and turn brown, requiring regular cleaning. Interestingly, what makes concrete cooling tower, a more economical option is the lower cost of pouring concrete. The most obvious advantage of concrete towers is their structural permanence and architectural flexibility. Properly designed concrete structures are nearly permanent with their mass making them highly resistant to weather events. They are unaffected by most chemicals, heat and ultra-violet exposure. Concrete is also inert to the water environment present, and helps to minimize radiated sound levels. All types of cooling tower can be made of concrete.
