Cooling Tower Refurbishment for Reliable Industrial Performance
An ageing cooling tower may still have years of productive service ahead of it. Worn fill media, damaged GRP panels, blocked nozzles, inefficient fans or corroded structural parts can reduce output, but these faults don’t always justify replacing the complete tower. Professional cooling tower refurbishment restores critical components, improves thermal performance and helps plant operators avoid unnecessary capital expenditure.
Lekwa Cooling Tower Services provides cooling tower refurbishment, repairs, maintenance, spares and replacement systems for industrial and commercial clients across South Africa and sub-Saharan Africa. Our experienced team works on package, GRP, mechanical draft, natural draft, cross flow, induced draft, field-erected and counter flow cooling towers.
When Does a Cooling Tower Need Refurbishment?
Performance loss often develops gradually. A plant may compensate by running fans for longer, increasing water flow or accepting higher process temperatures. These adjustments can hide the condition of the tower while energy use and operating costs continue to rise.
Cooling tower refurbishment should be considered when you notice:
- Rising cold-water temperatures or reduced cooling capacity
- Frequent motor, fan, gearbox or drive-system failures
- Damaged, blocked or deteriorated fill media
- Uneven water distribution across the fill
- Corrosion, cracks or deterioration in structural components
- Excessive vibration or unusual mechanical noise
- Water leakage from basins, joints, pipework or GRP sections
- Damaged drift eliminators or air inlet louvres
- Higher electricity and water consumption
- Increasing repair costs and unplanned shutdowns
A detailed inspection helps establish whether cooling tower refurbishment is technically and financially suitable. Lekwa assesses the structure, mechanical equipment, water distribution system, fill, drift eliminators, louvres and general operating condition before recommending the required work.
We have extensive work experience on the following cooling tower types:
Package cooling towers
GRP package cooling towers
Mechanical draft cooling towers
Natural draft cooling towers
Cross flow cooling towers
Induced draft cooling towers
Field erected cooling towers
Counter flow cooling towers

A Practical Cooling Tower Refurbishment Process
Every tower has different operating conditions, thermal duties and maintenance history. Refurbishment work must therefore be based on the actual condition of the system, rather than a standard replacement list.
1. Cooling Tower Inspection and Condition Assessment
The process begins with an inspection of the tower’s structural, mechanical and heat-transfer components. Technicians look for deterioration, wear, restricted airflow, poor water distribution and other faults affecting output.
Regular cooling tower preventative maintenance inspections can identify developing problems before major restoration becomes necessary. Where deterioration is already advanced, the findings are used to define the cooling tower refurbishment scope.
2. Performance and Component Evaluation
The tower must still meet the cooling requirements of the connected process or HVAC system. We assess whether existing components are correctly specified and whether deteriorated parts are restricting thermal performance.
This evaluation may cover the fan assembly, electric motor, gearbox, drive shaft, impeller, V-belts, distribution pipes, spray nozzles, fill media and drift eliminators. It also helps determine which parts can be repaired and which should be replaced.
3. Removal of Damaged Materials
Worn or damaged components are removed so that the supporting structure and internal areas can be properly inspected. Old fill blocks, broken louvres, blocked nozzles and deteriorated mechanical parts can conceal additional faults.
Cleaning is completed where required to remove scale, sludge, biological deposits and debris. This gives the cooling tower refurbishment team access to the areas requiring structural or mechanical repair.
4. Repairs, Replacement and System Upgrades
The approved cooling tower refurbishment work is then completed. Depending on the tower’s condition, this may include GRP repairs, replacement fill, new spray nozzles, distribution pipe repairs, fan refurbishment, motor replacement, gearbox work or structural restoration.
Lekwa supplies cooling tower spares suited to different tower configurations. Our cooling tower maintenance and services also cover cleaning, servicing, inspections, mechanical repairs and GRP-related work.
5. Reassembly and Operational Checks
After repairs and component replacements have been completed, the tower is reassembled and checked. Water distribution, fan operation, vibration, airflow and general mechanical operation must be assessed before the system returns to normal duty.
A correctly completed cooling tower refurbishment should address the causes of poor performance, not only the visible signs of wear.
Cooling Tower Parts That Can Be Refurbished or Replaced
The scope of cooling tower refurbishment depends on tower design, age, water quality, operating hours and exposure to the surrounding environment. Lekwa can attend to major operating areas within the system, including:
- PVC fill blocks and splash fill
- Drift eliminators and air inlet louvres
- Water distribution pipes, sprayers and nozzles
- Fans, impellers and hub assemblies
- Electric motors, gearboxes and V-belts
- Drive shafts and mechanical supports
- GRP panels, walkways and structural sections
- Water collection basins and sumps
- Pumps and associated pipework
- Stainless-steel fasteners and support components
Replacing deteriorated parts can improve airflow, increase water-to-air contact and restore more even water distribution. Mechanical work can also reduce vibration and help the fan system operate more reliably.
