Closed-circuit cooling tower repair in Egypt — used to protect sensitive systems from contamination. The cooling water flows through closed coils and never contacts the air directly. Brands: Baltimore Aircoil, Marley. Call **16062** for coil and pump service.
In a closed tower, the process water loop stays perfectly clean, and cooling is achieved by spraying external water over the coils as air passes through. This system reduces corrosion of the chiller and internal equipment. Common faults include external coil corrosion, spray pump failure, and clogged external spray nozzles.
The most frequent faults we encounter while servicing Closed-Loop — ranked by occurrence.
Corrosion and perforation of the heat-exchange coils (coil leakage) — 30%
Spray pump failure
Salt scaling on the external coil surface
Clogged secondary water spray nozzles
Faulty fan motor or gearbox
Corrosion of the external tower structure
Repairing and welding coil perforations or replacing the coils
Chemical cleaning of the external coil surface to remove salts
Servicing and replacing the secondary spray pumps
Cleaning and unclogging the external spray nozzles
Mechanical service of the fan, motor and gearbox
Renewing the metal structure insulation with rust-resistant materials
The key advantage is that the cooling water inside the building stays clean and free of salts and oxygen, which greatly extends the life of the chiller and internal equipment.
Yes, welding is possible for minor perforations, but if the corrosion is widespread, it is better to replace the whole coil for safety.
