For backup circulating water coolers, are there any good management methods?

Is there a leak after I put the backup cooler into operation?
Nitrogen is used for protection when it is shut down. When enabled, start the circulating water first, then gradually increase the heat flow.
If the equipment is broken and needs repair, start the circulating water first when turning it on, gradually increase the heat flow, and reverse the process when turning it off.
The spare one was repaired; it was kept for almost a year, but started leaking as soon as it was used
It’s because it wasn’t repaired at that time, or there was a problem with the sealing
After it was repaired, it wasn’t dried, and it corroded again
What to do if there is a leak in the circulating water?
It depends on what kind of material is leaking from you – organic or inorganic, soluble or insoluble, acidic or alkaline? This is the most straightforward assessment; material leakage can also cause a range of water quality issues, such as microorganisms, silt, and turbidity
I mean, since the valve for the circulating water in the backup cooler is leaking, it’s impossible for the tube bundle to dry out. So what should I do? Pour water on it, or leave it open?
What I mean is that the valve for the circulating water in the backup cooler doesn’t close properly, and the tube bundle can’t be dried out. Should I activate the water circuit, or what?
If that is the case, the heat exchanger should ensure a certain flow rate and volume flow. If it cannot be guaranteed all the time, at least a few hours per day should be ensured. Furthermore, the pH value of the circulating water should preferably be kept below 8.2, and agents with strong corrosion-inhibiting properties should be used for protection
