At Coolclean, we specialise in delivering industry-leading cooling tower deep cleaning and maintenance services designed to restore systems to peak efficiency and ensure compliance with hygiene, water quality, and safety standards.
Our recent Cooling Tower Engineering Performance Service at a major hospital facility demonstrates the value of comprehensive cleaning for performance, reliability, and risk reduction.
Cooling towers naturally develop scale, sediment, organic buildup, and corrosion over time. Without scheduled maintenance, these issues can lead to reduced cooling performance, higher energy and water consumption, bacterial growth, and premature equipment failure. Coolclean’s Service addresses both contamination and structural integrity, supporting long-term system health.

What is Engineering Performance Service?
Comprehensive Service: Super clean, deep clean, mechanical maintenance, routine compliance cleaning, and component inspection.
Reporting includes: One report per unit, with photos, comments, and recommendations.
Engineering Performance Service is a comprehensive and specialised service designed to assess and maintain cooling towers from an engineering perspective. Unlike traditional maintenance services that focus on routine cleaning, this service offers a full-scale evaluation aimed at ensuring the optimal performance and longevity of cooling towers. This approach is rooted in a deep understanding of engineering principles and a commitment to applying the latest technological advancements in the field.
Comprehensive Assessment
The Engineering Performance Service includes a range of detailed assessment activities, each designed to provide a thorough understanding of the current state of a cooling tower. These activities include:
- Detailed Inspection: The Coolclean team conducts a thorough examination of all components of the cooling tower. This inspection is meticulous and aims to identify any potential issues or areas of concern that could affect the performance and efficiency of the cooling tower. They look at everything from structural components to operational systems to ensure nothing is overlooked.
- Photographic Documentation: To ensure complete transparency and provide a clear visual record, Coolclean takes high-quality photos throughout the assessment process. These photos document the condition of various components of the cooling tower, highlighting any issues or areas that require attention. This visual documentation is an invaluable tool for understanding the current state of the cooling tower and for planning future maintenance activities.
- Comprehensive Report: At the conclusion of the assessment, Coolclean provides a detailed report summarizing their findings. This report is comprehensive and includes:
- Comments: Expert insights and observations on the current state of the cooling tower. The Coolclean team provides detailed notes on any issues identified during the inspection, along with their potential impact on the performance and efficiency of the cooling tower.
- Recommendations: Based on their findings, Coolclean offers actionable advice on necessary repairs, upgrades, or maintenance tasks. These recommendations are designed to address any issues identified during the inspection and to enhance the performance and longevity of the cooling tower.
- Quotations: To ensure complete transparency and facilitate budget planning, Coolclean provides cost estimates for any recommended work. These quotations are detailed and cover all aspects of the recommended repairs or upgrades, helping clients make informed decisions about their maintenance activities.

A fully maintained cooling tower delivers major operational and safety benefits, including:
- Improved thermal performance
- Reduced energy and water usage
- Lower bacterial growth and Legionella risk
- Longer lifespan of internal components
- Compliance with environmental and safety regulations
For hospitals and healthcare facilities, where air and water quality are critical, a high-standard cooling tower cleaning service is essential.
Coolclean’s Engineering Performance Service at the Hospital Facility
Our certified technicians completed a full, step-by-step restoration of the cooling tower, combining mechanical cleaning, chemical treatment, and structural assessment.
Equipment isolated and locked out
Access hatch removed
- Safety Preparations
We began by completing all permits and Job Safety Analyses (JSAs), establishing safe access and lockouts. The recirculation pump was confirmed operational to ensure proper disinfection.
- Pre-Disinfection
Sodium hypochlorite was dosed to maintain 10 ppm at 7.0–7.6 pH for one hour, ensuring safe entry and initial microbial reduction.
- Disassembly for Full Access
To expose all internal areas for cleaning, we removed:
- Access panels
- Louvres
- Drift eliminators
- Screens
Nozzles and strainers were inspected and cleared to restore proper water distribution.
- Fill Pack & Internal Cleaning
The fill pack was removed and pressure cleaned block by block.
The internal casing was also pressure cleaned to eliminate:
- Scale
- Biofilm
- Organic contamination
- Sediment buildup
Dirty fill pack and drift eliminators out
Parts after cleaning

- Basin & Sump Cleaning
Sludge, debris, and solids were removed from the basin and sump—areas that often harbour bacteria and reduce overall system efficiency.
- System Reassembly & Restart
After cleaning:
- Fill pack was reinstalled
- Panels, louvres, and drift eliminators were refitted
- The system was refilled and recirculation restarted
- A final disinfection dose was applied
This returned the cooling tower to a clean, stable, and operational condition
Comprehensive Report: Inspection Findings & Recommended Works
During the process, our team identified several issues requiring corrective action to restore full system integrity and prevent future failures.
- Cooling Tower Basin Leakage
The basin is leaking from several areas, indicating significant coating deterioration.
Recommendation: Complete basins reseal.
- Corroded Interior Casing Walls
Casing walls show advanced corrosion with bubbling and deteriorating coatings.
Recommendation: Strip and recoat interior casing.
- Severely Deteriorated Fill Pack
The fill pack is brittle and has lost structural integrity, reducing cooling efficiency.
Recommendation: Full fill pack replacement.
- Inadequate Sunlight Prevention
An open section at the top of the tower is allowing sunlight into the system, encouraging algae growth.
Recommendation: Install proper shading or light prevention barriers.
- Corroded Motor Mount & Fan Pulley
Mechanical corrosion may affect reliability and system safety.
Recommendation: Inspect, repair, or replace corroded components.
- Water Leaks from Distribution System
Water is leaking into the fan airstream, causing drift loss and potential contamination.
Recommendation: Repair leaks and reseal distribution components.
- Damaged Rubber Water Deflectors
Deflectors are tearing away from the structure, reducing water control.
Recommendation: Replace damaged water deflectors.
A Cleaner, Safer, More Efficient Cooling Tower
Coolclean’s Cooling Tower Engineering Performance Service restored cleanliness, airflow, water quality, and operational reliability at the hospital facility. While further repairs are required to address structural degradation, the Super Clean provided a stable foundation for improved performance and ongoing maintenance.
We service hospitals, commercial buildings, industrial plants, and large facilities across Australia. Contact Coolclean today to book your Cooling Tower Engineering Performance Service or request a full cooling tower assessment.
