Providing Cooling Tower Repairs & Maintenance Across South Africa & Sub-Saharan Africa – Lekwa Cooling Tower Services
When a cooling tower starts losing performance, develops mechanical faults or shows signs of structural deterioration, the problem can quickly affect the rest of the plant. Higher water temperatures, unstable process cooling, increased energy use and unplanned downtime are all signs that the tower needs professional attention.
Lekwa Cooling Tower Services provides specialist cooling tower repairs for industrial and commercial cooling systems across South Africa and sub-Saharan Africa. Our team works on cooling towers of different makes, sizes and configurations, helping clients repair damaged components, restore reliable operation and extend the usable life of existing equipment.

Professional Cooling Tower Repair Services
Cooling towers operate under demanding conditions. Water, heat, vibration, chemicals, airborne contaminants and constant mechanical movement all contribute to wear over time. Some faults are obvious, such as a damaged fan or leaking basin. Others develop gradually and only become noticeable when the tower can no longer maintain the required cold-water temperature.
Our cooling tower repairs can address mechanical, structural, water-distribution and heat-transfer problems. Depending on the tower and the condition found on site, repair work may include:
- Fan, impeller, hub and drive-system repairs
- Gearbox, motor, shaft, coupling and V-belt replacement
- Damaged or blocked spray nozzle replacement
- Water distribution pipe and sprayer repairs
- PVC fill and splash fill replacement
- Drift eliminator and air inlet louvre replacement
- GRP panel, casing and walkway repairs
- Basin, sump and water leak repairs
- Structural repairs and restoration
- Corrosion-damaged component replacement
- Cooling tower cleaning and removal of scale, sludge or debris
Where a repair requires new parts, LCTS can also supply cooling tower spares for locally manufactured and imported systems. Parts supply and site work can therefore be coordinated through one specialist contractor.
Signs Your Cooling Tower Needs Repairs
A cooling tower rarely fails without warning. Small changes in performance can indicate developing mechanical or internal problems, and dealing with them early can reduce the risk of a larger breakdown.
Contact LCTS for a cooling tower repair assessment if you notice rising process temperatures, reduced cooling capacity, unusual fan noise, excessive vibration, visible water leaks, deteriorated fill, damaged louvres, blocked nozzles, uneven water distribution or recurring gearbox and motor problems.
Higher electricity or water consumption can also point to a tower that is no longer operating as intended. If airflow is restricted or water isn’t being distributed correctly across the fill, the cooling tower may work harder while delivering less effective heat rejection.
Planned cooling tower preventative maintenance inspections can help identify wear before it develops into a costly shutdown. Where damage is already present, our technicians can define the required cooling tower repairs and prioritise critical work.
Mechanical Cooling Tower Repairs
Mechanical components are central to dependable tower operation. Fans, motors, gearboxes, drive shafts, bearings, couplings and belts operate for long periods and may be exposed to moisture, vibration and heavy loads.
LCTS carries out cooling tower repairs on mechanical assemblies where practical and replaces components when continued use could compromise reliability. We also check related parts rather than treating one failed item in isolation. A damaged coupling, for example, may be linked to misalignment, vibration or wear elsewhere in the drive system.
Structural, GRP and Water Distribution Repairs
Cooling tower performance is not only determined by the fan system. Damaged casing, deteriorated GRP sections, leaking basins, corroded supports, worn fill and poorly functioning distribution systems can all reduce efficiency or create safety concerns.
Our industrial cooling tower repairs can include GRP repairs, structural work, concrete repairs, basin restoration and replacement of damaged internal components. Water distribution piping, spray systems and nozzles are checked for blockages, damage and uneven flow because poor distribution leaves sections of fill underused and reduces heat-transfer performance.
LCTS also provides dedicated cooling tower maintenance and services for clients who want planned servicing alongside repair work. This allows recurring problems, component wear and general tower condition to be managed more proactively.
Repair or Refurbish the Cooling Tower?
Not every ageing tower needs to be replaced. In many cases, targeted cooling tower repairs can correct a specific problem and return the unit to dependable service. Where wear is more extensive, a larger refurbishment may be the better option.
A refurbishment can involve replacing multiple internal and mechanical components, restoring structural sections and improving overall tower performance as one coordinated project. LCTS provides cooling tower refurbishment for package, GRP, mechanical draft, natural draft, cross flow, induced draft, field-erected and counter flow cooling towers.
Our assessment considers the condition of the existing tower, the extent of deterioration, the repair history and the cooling duty required by your process. If repairing isolated components is practical, we’ll focus the scope accordingly. If the tower has widespread deterioration, we can recommend a more comprehensive solution.

Cooling Tower Repairs Done Fast and Right
When a tower goes down, your production takes a hit. That’s why we respond quickly to calls for cooling tower repairs. Whether it’s a faulty motor, cracked casing, or collapsed fill pack, our teams have the tools and parts to get your system back online quickly.
We handle both mechanical and structural repairs on-site. Our crews are trained to work safely within live industrial environments, meaning minimal disruption while the repair is completed.
For urgent assistance, you can reach us through our contact page. We’re always ready to assist across the Eastern Cape and beyond.
Cooling Tower Repairs for Different Tower Types
LCTS has experience working on cooling towers used in industrial and commercial applications. Our repair teams can assist with package cooling towers, GRP towers, cross flow towers, counter flow towers, induced draft systems, mechanical draft towers, natural draft towers and large field-erected cooling towers.
Because tower designs vary, cooling tower repair services should be based on the actual configuration on site. Access, materials, fan arrangement, water distribution and structural design all influence how repairs should be planned and carried out.
If an existing tower has reached the point where repairs are no longer commercially sensible, LCTS can also assist with new or refurbished cooling towers suited to the application.

Frequently Asked Questions (FAQs) – Cooling Towers by Lekwa Cooling Tower Services
Cooling tower maintenance is crucial to ensure the efficient and reliable operation of the cooling system. It helps prevent issues such as scaling, corrosion, and biological growth, which can compromise performance and lead to costly repairs.
The frequency of cooling tower maintenance depends on factors such as the type of cooling tower, environmental conditions, and usage. However, as a general guideline, regular preventative maintenance should be performed at least twice a year.
Cleaning involves the removal of debris, scale, and biological growth from various components such as water distribution piping, sprayers, drift eliminators, air inlet louvres, and fill. This ensures optimal heat exchange and prevents blockages.
Mechanical services may include the refurbishment or replacement of impellers, electric motors, gearboxes, shafts, and v-belts. These components are critical for the mechanical functioning of the cooling tower.
Many cooling towers have components made of glass reinforced plastic (GRP). Repairing and maintaining these components are essential to preserving the structural integrity of the cooling tower and preventing issues like leaks.
Signs of potential issues include reduced heat exchange efficiency, unusual noises, visible corrosion, or increased water consumption. If any of these signs are observed, it is advisable to schedule maintenance promptly.
