I would recommend that you implement both of the cooling towers
with a controlled diverter valve just upstream of them. There are a
number of controller models that you could then implement to watch
the the ambient temperature and change the setting on the controlled
diverter valve so that your water flow would go to one tower or the
other depending on the ambient temperature. You would then need to
implement a mixing valve downstream of the towers so that the water
flow would return to its load from whichever tower it passed
through. <br>

<div>How can i simulate a dry cooling tower with spray system
