Three Ways to Make Your Cooling Tower More Sustainable
Energy Efficiency
Choosing a correctly sized cooling tower and keeping it well maintained helps it deliver the required cooling with less fan energy. Clean fill, well-aligned drive systems and efficient fans all help reduce energy consumption.
Water Efficiency
Evaporation is how a cooling tower works, but unnecessary water losses can be reduced. Effective drift eliminators, well-maintained water distribution and good water management all help reduce make-up water and blowdown.
Longer Equipment Life
Replacing worn components such as fill, drift eliminators, fans, nozzles and drive systems can restore performance without replacing the entire tower, reducing waste, cost and downtime.
How We Help You Run More Sustainably
Our services support sustainability at every stage of a cooling tower's life:
Consultation and problem analysis to identify performance issues and opportunities for improvement.
Selection and supply of Marley equipment matched to your cooling load and site conditions.
Testing and commissioning to confirm the system performs as designed from day one.
Parts replacement and ongoing maintenance to keep your cooling tower efficient for years to come.
Experience on Large-Scale Cooling Systems
Our project experience includes district cooling systems at Gardens by the Bay, the Singapore Sports Hub and Sentosa Island, where a central plant provides cooling for multiple buildings. We also support cooling systems for petrochemical, semiconductor, pharmaceutical and healthcare facilities across Singapore.
Frequently Asked Questions
Are Marley cooling towers green building certified in Singapore?
Yes. Marley NC Steel cooling towers supplied by Stolz Engineering Pte. Ltd. are certified under the Singapore Green Building Product (SGBP) scheme by the Singapore Green Building Council, with selected models rated Very Good (2 Ticks) and others rated Good (1 Tick). Certification is valid until 12 August 2028.
How can I reduce my cooling tower's energy use?
Regular maintenance is one of the most effective steps. Clean fill, properly working fans and well-aligned drive systems help the tower deliver the required cooling with less energy. Our team can assess your cooling tower and recommend improvements.
How can cooling tower water use be reduced?
Water losses can be reduced by keeping drift eliminators in good condition, maintaining the water distribution system and managing water treatment effectively to reduce blowdown.
Should I repair or replace an old cooling tower?
It depends on the tower's condition. In many cases, replacing key components such as fill, fans or drive systems restores performance at a lower cost than a full replacement. We can inspect your tower and advise on the most cost-effective option.
