we have two 300 HP vertical discharge, cross flow cooling towers. the location is the Sonora desert (HOT). the original use is condenser water for two HVAC chillers.
A varity of equipment using the tower water has been added without much thought to tower capacity.
I'm thinking to purchase a new larger tower(s) and wonder of there are any operational problems of low flow over the fill, reduced capacity etc. caused by oversizing the tower by a factor of 2 or 3.
