Which of the following is NOT a characteristic of Venturi towers?

Venturi towers are designed to be efficient cooling systems with several distinct characteristics, and one of their notable features is that they operate without requiring a fan to move the air through the system. This is achieved through the natural draft created by the design of the tower, which allows air to enter at the base and exit at the top, utilizing the Venturi effect to enhance airflow.

In addition to the elimination of fans, Venturi towers offer quiet operation, which makes them ideal for locations where noise may be a concern. Their design minimizes mechanical components that could contribute to noise pollution.

Moreover, one of the advantages of Venturi towers is that they typically have reduced maintenance requirements, mainly because they involve fewer moving parts compared to more conventional cooling towers that rely on mechanical fans. This reduced maintenance is a significant benefit because it leads to lower operational costs and less downtime for repairs.

On the other hand, the notion that Venturi towers require an elaborate fill setup is not characteristic of their design. In contrast, many cooling tower designs mandate intricate fill systems to optimize water and air contact area for heat exchange. Venturi towers, however, utilize their unique structural design to achieve efficient cooling with a simpler internal configuration, which limits the complexity of the fill setup.
