Nowadays, fanless cooling towers are much more favored in India because of their low energy consumption and maintenance charges. Contrary to the other cooling towers that use fan ventilation, fanless towers rely on natural drafts of air and gravity in their operations and, therefore, are environmentally friendly and cheap. However, routine maintenance is necessary to maintain the efficiency of those systems from time to time. In this blog, we have highlighted the measures and step-by-step processes to sustain the fanless cooling tower and keep it in the best-performing state for the lifetime extension of the equipment.
Understanding Fanless Cooling Towers
The fanless cooling towers rely on natural drafts of air and gravity, which makes them highly unique. This design does not utilize fans, which are nowadays a large consumer of energy and a mechanical component that has a tendency to degrade rather quickly. They are therefore considered as energy savers.
Importance of Regular Maintenance
Some problems that can be eradicated through efficient maintenance of the fanless cooling towers are the scaling of water, corrosion of the cooling tower and aeration, and biofouling problems. These problems are destructive if not controlled, as they lead to the poor performance of the cooling tower and expensive charges towards the structures.

Conduct Regular Inspections
Monthly Check-Ups
The towers should be inspected monthly to determine if there is a form of wear and tear, such as cracking, leakage, and structure problems. Also, ensure that the fill media and the distribution areas are not being occupied by other objects that may hinder the functioning of the towers.
Visual and Functional Checks
Conditions that one may consider during inspections of the tower include whether there is a physical menace to some of the infrastructural parts of the building. Ensure that the function of the water distributors is not hindered by any problems to enable water flow.

Maintain the Fill Media
Cleaning Procedures
The fill media in the case of fanless cooling towers works effectively in a clean cooling circuit. But occasionally, particles and minerals might deposit themselves onto the tower, which will gradually reduce its ability in the long term. Rinse the fill media with a powerful water jet to remove debris and deposit that may have piled at any of the media.
Preventative Measures
To prevent the quantity of debris from penetrating the tanks, it is necessary to use some screens or filters for the water supply. This way, the large particles are not admitted into the system and pollute the regular pillar of the dosage.

Monitor and Manage Water Quality
Regular Testing
Proper water quality is essential for the proper functioning of the cooling towers. Check the pH level, hardness, and contaminants of the using water as often as possible. Scaling and corrosion also affect the tower and its performance, and water chemistry minimizes them.
Water Treatment
Chemicals used for water treatment should be highly effective in order to have optimum quality water. Biocides slow down microbial growth, and in turn they slow down scale formation, while corrosion inhibitors preserves the metal parts of equipment.

Combat Scaling and Corrosion
Scaling Prevention
Scaling is also common in the cooling tower since it involves the depositing of minerals within the water on the surfaces of the surrounding cooling tower. As a measure of protection against scaling, there should be balanced water chemistry and scaling inhibitors.
Address Corrosion
Corrosion means the loss of the strength of your material or the weakening of the structure of the cooling tower. Minimize the use of water that causes corrosion and stabilize its pH and also use anti- corrosive agents on metal parts. Because most of the time, rust is considered as the first indicator for corrosion in the metals.
Professional Maintenance Services
Certainly, primary building works should be accomplished periodically, but some activities should be done by a GS specialist. Cooling tower specialists should be hired on an annual basis to conduct other specific examinations, execute different sanitation processes, and for addressing other complications that might not be seen during routine check-ups.
Conclusion
Maintenance is the key when it comes to the functionality and longevity of your fanless cooling tower. It is therefore important to carry out checks and perform a proper cleaning on a monthly basis to avoid damage. Thus, do not wait for such problems to happen; take action today to keep your cooling tower in perfect condition!
