Fan is a prime mover and is responsible to generate negative pressure inside the fan stack to get maximum air inlet. Generally, cooling towers are equipped with axial flow propeller type fans, either directly driven by motor or by gearbox. They play a key role in the efficiency of a cooling tower if designed aerodynamically.
It is defined as the ratio of the desired heat loss through the system upon the input power to the cooling tower. The complete design of a cooling tower can give you good efficiency.
SFG cooling towers gives the best efficiency in comparison to any competitor due to its researched thermal design which gives it versatility to perform even at humidity levels as high as 90-95%.
It is a tank provided at the bottom of the scrubber column which contains the neutralizing liquid inside it. It is connected to a recirculation pump which recirculates the liquid inside the scrubber column.
