Algae growth in a cooling tower is a significant M&E threat in the humid, sun-drenched environment of Kuala Lumpur and Selangor. Beyond being an eyesore, algae acts as a "biological insulator" on your infill and a breeding ground for Legionella bacteria. If left untreated, it slimes the heat exchange surfaces, causing your chiller's condensing pressure to spike and your TNB bills to soar.
EKG M&E Sdn Bhd provides professional chemical and mechanical algae eradication to restore your tower's thermal efficiency.
A bucket of chlorine is not a solution; it is a temporary fix. Our engineering approach addresses the root cause:
We begin by physically removing the "bio-mat" from the internal surfaces.
Infill Deep Clean: We use specialized low-pressure, high-volume water jets to flush the honeycomb infill. Using too much pressure can shatter brittle PVC, so we calibrate the force to remove the algae while preserving the media.
Basin Scrubbing: The cold-water basin is drained and mechanically scrubbed to remove the "sludge" layer where algae spores hibernate.
Once the bulk mass is removed, we apply industrial-grade oxidizing and non-oxidizing biocides.
The Logic: Algae can become "immune" to a single chemical. We alternate between different biocide types to ensure total cellular breakdown of the remaining spores.
Bio-Dispersants: We add dispersants that "loosen" the protective slime layer (biofilm) that algae uses to cling to pipework and heat exchanger tubes.
Algae often clogs the spray nozzles, creating "Dry Spots" on the infill. These dry spots allow more sunlight to penetrate the tower, accelerating further algae growth.
The Fix: We chemically dip and clear all nozzles to ensure a 100% uniform "Rain Pattern."
As an HVAC and Clean Air Specialist, we focus on long-term prevention through system design:
Filtration Upgrades (Sand/Disk Filters): We install side-stream filtration to remove the organic "food source" (dust and pollen) that algae needs to grow.
VFD-Controlled Fan Logic: By utilizing Variable Frequency Drives (VFDs), we can ensure the fan maintains optimal airflow. Proper airflow keeps the water temperature within a range that is less hospitable to rapid biological blooms.
UV Sterilization Integration: For high-sensitivity sites (Hospitals or Data Centers), we can integrate UV-C lamps into the water loop to kill spores instantly without increasing the chemical load of the water.
| Feature | Clogged / Algae-Ridden Tower | Cleaned & Treated Tower |
| Chiller Efficiency | Low (High Head Pressure). | Optimal (Design Approach Temp). |
| Water Flow | Restricted / Channeling. | Uniform (Maximum Heat Transfer). |
| Health Risk | High (Legionella breeding). | Low (MOH Compliant). |
| TNB Energy Cost | Spiking (Chiller works harder). | Lowered (Efficient Heat Rejection). |
Compliance Documentation: We provide a full service report, including pre-and-post "Dip Slide" tests to prove the biological count is within safe Malaysian health standards.
Chemical Balancing: We ensure the pH and conductivity of your water are balanced after treatment to prevent the "Shock" chemicals from corroding your expensive chiller tubes.
Strategic Support: Based in Kuala Lumpur, we provide turnkey cleaning, structural repairs, and monthly water treatment programs for commercial buildings.
