Cooling Towers In Parallel

Cooling Towers In Parallel

Whenever cooling towers are to be installed in parallel with common supply and return piping, special consideration should be given to the piping design to ensure balanced water flow through each tower. Otherwise, unequal water levels could develop in the tower basins which, in the extreme, could cause one tower to overflow constantly while air is being drawn through the other into the circulating pump.

To avoid this condition,  BAC’s recommendations can be found in the technical resource document Cooling Towers in Parallel.
