Cooling Tower Maintenance Tips To Help Save Energy

Posted on

Over a period of time, a cooling tower that has not been properly maintained will be unable to operate at its optimum performance level. To be more specific, the temperature of the water that leaves such a cooling tower will slowly increase, leading to a less efficient tower and increased energy costs for the company. It is vital that a proper maintenance schedule is developed and adhered to in order to get the most energy effective performances from the tower. This article examines some tips to help keep the tower operating as efficiently as possible.

Preliminary Checks

Before any hands-on maintenance is carried out, inspect the general condition of the tower. As you do so, listen out for any abnormal operating noises. Identifying an issue before it becomes a major problem will save time and money. Before attempting the following tips, ensure that proper safety procedures are followed, such as disconnecting motor switches and adhering to lock out procedures.


There are several areas that can be checked to make sure they are operating normally. Begin with the strainers and check to make sure they are clear of debris. The water distribution system should be checked next. Look at the coils and check for any scale build-up. If the water is not being distributed correctly over the coils, scale will build up. If this is the case, inspect the water nozzles for clogs or cracks. Move on to the water supply and check that the water is at the correct pre-determined level. The correct water level here will reduce air entrainment and conserve water. Inspect the quality and quantity of oil and shaft alignment of the gears and refill or adjust if necessary.

Hands-On Maintenance

The bleed rate can be adjusted to ensure the build-up of solid matter in recirculating water is avoided. Adjust it according to the quality of the local water supply and the regulations regarding water evaporation rates. Any dirt or debris that has accumulated in the cold water basin can be carried through the sump of the tower. Flush the cold water basin to prevent this. Move on to the drive belt and check and adjust if there are any tension problems. The correct tension ensures the drive belt system works as it should. Finally, shaft bearings should be lubricated around every three months to ensure optimum performance. Automatic bearing greasers can also be installed, cutting down on the need to check the bearings so regularly.

These tips should allow the water tower to work properly, saving energy and money. If you have specific questions regarding the functionality of your cooling tower, get in touch with a business like Breezewater Pty Ltd to learn more about maintenance options.
