The Importance of Cleaning Cooling Towers
As we approach cooling season in the Northeast, it’s important for property managers and building operators to strategically plan their cooling tower cleanings to avoid disruption in service. Regular maintenance, including routine inspections and cleaning of cooling towers, is crucial to reduce the risk of potential health hazards associated with water borne pathogens and bacteria such as Legionella. Cleaning also ensures efficient operation with reduced energy consumption and cost-savings, while extending the lifespan of the system.
How often do cooling towers need to be cleaned?
Regulations and Industry Guidelines, including OSHA, recommend cleaning cooling towers at least once per year for seasonally operated towers, and twice per year for year-round towers. However, if there are signs of debris, sediment or other build-up more frequent cleanings may be needed. Physical cleaning of the tower should always be preceded by the addition of a specially formulated disinfecting cleaner circulated for 24-48 hours. This crucial step helps lift and loosen sediment and debris, and results in a much more thorough cleaning. Once cleaned, a micro-biocide is added to further inhibit micro-biological growth.
Identifying Common Problems Requiring Cooling Tower Cleanings
- Energy Efficiency
Problem: Dirty cooling towers reduce the heat transfer efficiency of the system, which leads to increased energy consumption and higher operating costs.
Solution: Routine cleanings maintain and restore the system’s efficiency and reduce energy consumption.
- Microbial Growth
Problem: The growth of harmful microorganisms such as Legionella bacteria can cause serious health issues. Sediment and debris can become a food source and a place for bacteria to hide from disinfectant.
Solution: Regular cleaning and disinfection of the cooling tower can reduce the growth and spread of these microorganisms and protect the health of the building’s occupants and the surrounding community.
- Corrosion
Problem: Buildup of sediment and other debris in a cooling tower can cause corrosion and damage to the system. Corrosion can lead to leaks, reduced efficiency, and even system failure.
Solution: Cleaning prevents corrosion and prolongs the lifespan of the cooling tower.
- Compliance with Regulations
Problem: Many precincts and industries are subject to regulations and guidelines regarding the operation and maintenance of cooling towers, including the prevention of Legionella bacteria.
Solution: Cleaning and maintenance ensures compliance with regulations and prevents legal issues.
Avoid Cooling Tower Problems with Regular Cleanings and Maintenance
Regular cooling tower cleaning is essential for optimal performance, health and safety, and compliance with regulations. By scheduling routine service from a licensed professional, buildings can ensure their systems are operating efficiently and effectively, while protecting their investment and the health of their occupants.
