How many months does the cooling tower usually take to cool?

It depends on the local weather conditions. It's too cold, and the risk of freezing becomes greater. It usually takes two or three months.

Please note the following points:

An electric heating device is installed in the water pan of the cooling tower to prevent freezing. return pipe may need electric heat tracing.

If an open cooling tower is used, attention should be paid to filtration and water quality control. This may lead to scaling or blockage of the fan coil.

If a closed cooling tower is used, it is easier to control and the service season is longer. Ethylene glycol should be added to the water in the closed tower coil to prevent freezing. In cold weather, it is not necessary to turn on the spray pump and discharge the circulating water. When the weather is cold, you can also stop the fan.
