Open-circuit cooling tower repair in Egypt — the most widespread and efficient type of evaporative cooling. Water is sprayed directly over the fill to contact ambient air. Common brands: BAC, Marley, Evapco. Call **16062** for periodic service that ensures top efficiency.
In an open tower, the cooling water makes direct contact with ambient air, evaporating part of the water and rejecting heat. This system needs intensive water treatment because the water is constantly exposed to external contamination and dust. Common faults are clogged spray nozzles, algae buildup in the lower basin, and fan corrosion.
The most frequent faults we encounter while servicing Open-Loop — ranked by occurrence.
Clogged spray nozzles — 40%
Salt and algae buildup on the fill pack (fill pack scaling)
Make-up float valve failure
Worn fan motor bearings
Worn or snapped V-belts
Clogged suction strainer
Damaged drift eliminators (increased water loss)
Corrosion of the metal basin and water leakage
Cleaning and unclogging spray nozzles and replacing damaged ones
Chemical washing of the fill to remove salts and algae
Repairing and replacing float and make-up valves
Replacing genuine motor bearings and belts
Cleaning and sanitizing the lower basin and strainers
Replacing the drift eliminators to reduce water loss
Sealing and restoring fiberglass water basins
Mechanical balancing of the fans to ensure stability
Usually the drift eliminators are damaged or broken; they are responsible for catching water droplets and stopping them escaping with the air. They must be replaced immediately to save water. Call 16062.
If the clogging is very hard scale, chemical cleaning may not work and the fill must be replaced to restore cooling efficiency.
5 to 8 years depending on the water treatment quality and the type of fill used.
On-site diagnosis, clear pricing before any work, and a 6-month written warranty.
