Since a cooling tower is designed to remove the heat from circulating water that is moving through a condenser, maintaining your cooling tower is the key to efficiency and high performance. This means that if your cooling tower is not properly maintained and if you are not familiar with the main causes of poor performance, you will end up with cooling water that is at a warmer temperature than it should be. The condenser temperature will also rise as a result. It is important that you know what the causes of poor cooling tower performance are so that you can maintain your tower in a way to prevent against them.

Scale 

It is possible for scale deposits to build up within your cooling tower. This is due to the fact that when water evaporates, the minerals in the water can leave behind a residue. This residue is a scale deposit that can make it difficult for the water to heat up efficiently. If you have scale build up on your cooling tank, this means that the water is not being treated correctly. There are minerals in water that can transform into scale deposits once the water evaporates. To prevent against the buildup of scale deposits within your cooling tower, you can make sure that you bleed out the tower regularly to make sure that the water is not cycled over and over again resulting in increased amounts of minerals.

Air

Another culprit of poor performance with your cooling tower is poor air flow within the tower. The fan motor can become loose over time or the alignment of the fan can be off, which results in the air flow being anything but ideal. It is even possible for damage to occur to the fan blades that make air flow compromised. Be sure that the fan system within the cooling tower is evaluated and maintained regularly to ensure that air flow problems are not the cause of poor performance. If air flow is poor, it is possible that the amount of heat transferred from the water to air is reduced at a high rate. If the fan is not fixed quickly when air flow is compromised, the motor might fail as a result.

Spray Nozzle

It is also common for the spray nozzle on the cooling tower to become clogged over time. This can be due to algae and sediment buildup. When the spray nozzle becomes clogged, the result can be poor heat transfer within the tower. You can add water treatment to the cooling tower in order to prevent against the buildup of sediment and algae on the spray nozzles.
