Cooling Tower Preventative Maintenance Inspections
Why Lekwa Cooling Tower Services Sets the Benchmark when it Comes to Cooling Tower Maintenance, Repairs and Installation.
Cooling towers play a vital role in heat rejection systems across industrial and HVAC operations. To ensure peak efficiency and operational reliability, scheduled preventative maintenance inspections are non-negotiable. At Lekwa Cooling Tower Services, we specialise in industrial cooling tower services that help businesses maintain compliance, reduce downtime, and extend the lifespan of their cooling infrastructure.
Why Preventative Maintenance Inspections Are Essential
Routine cooling tower inspection and preventative maintenance for cooling systems are not simply good practices – they are critical to operational safety and cost efficiency. A well-maintained cooling tower supports consistent thermal performance, protects against health risks such as Legionella, and meets national compliance standards, including SANS 893 parts 1 and 2 and ISO 16345:2014.
When inspections are neglected, systems become vulnerable to inefficiencies, bacterial contamination, component failure, and escalating repair costs. Lekwa Cooling Tower Services ensures your maintenance schedule is aligned with performance, compliance, and safety objectives.

Key Inspection Areas: What Our Technicians Evaluate
Our certified cooling tower technicians follow a comprehensive checklist covering all structural, mechanical, and water system components. Here are some of the critical checkpoints during scheduled cooling tower inspections:
Structural and Component Integrity
- Cooling tower condition assessment
- Structural integrity inspection for corrosion, rust, and wear
- Basin and sump inspection for sediment buildup
- Fill media condition check to ensure water distribution efficiency
Mechanical Performance
- Fan blade wear inspection and cooling tower fan alignment
- Gearbox and motor inspection
- Lubrication of bearings and shafts to minimise friction and wear
- Motor and drive belt tension checks to prevent mechanical strain
Hydraulic Efficiency
- Nozzle blockages and alignment review
- Float valve adjustment for precise water level control
- Water distribution system inspection
- Cooling tower vibration testing to detect potential imbalance
Health and Safety Compliance
- Inspection of corrosion and scaling, which can impact both performance and hygiene
- Legionella risk assessment and evaluation of your water treatment programme
- Recording of water quality parameters like pH, conductivity, and bacterial counts
- Review of compliance with SANS 893 requirements
We also prepare a comprehensive cooling tower inspection report after each visit, detailing findings, actions taken, and recommendations.
Customised Maintenance Schedules
No two facilities are the same, which is why we provide tailored cooling tower servicing plans. Depending on your operational intensity, we offer:
- Quarterly cooling tower inspections
- Annual cooling tower maintenance
- On-demand emergency cooling tower repair
We help facility managers stay ahead of potential failures with a data-driven cooling tower maintenance schedule that meets both production and compliance demands. Our approach aligns closely with national safety regulations and ensures consistent documentation of routine cooling tower inspection outcomes.
Cleaning and Refurbishment Services
Proper cleaning is an essential part of preventative maintenance for cooling systems. Dirt, scale, and biological matter can quickly accumulate, compromising efficiency and fostering bacterial growth. Our team offers:
- Scheduled cooling tower cleaning procedures
- Complete cooling tower refurbishment services
- Disinfection and sanitation in line with Legionella control regulations
Where structural degradation or ageing parts are found, we can overhaul or replace them entirely, offering cost-effective refurbishment solutions that delay the need for full system replacement.
Maintenance and Performance Monitoring
Performance monitoring is central to effective cooling tower maintenance. Lekwa Cooling Tower Services provides ongoing support to ensure:
- Optimised thermal performance assessment
- Accurate tower efficiency testing

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.
