Cooling Tower Repairs & Refurbishment

Containerised and induced draft towers

Fill, drift eliminators and nozzles

Casing, motor and drive repairs

Legionella auditing and sampling

Cooling tower repairs, refurbishment and Legionella auditing for industrial and commercial cooling towers in Townsville and North Queensland.

Eureka Water & Filtration refurbishes and repairs containerised and induced draft cooling towers across Queensland, from Townsville, Cairns, Mackay and Mount Isa to Brisbane. We replace fill media, drift eliminators and spray nozzles, repair casings, replace motors and drives, and carry out Legionella auditing and water sampling in line with AS/NZS 3666.

Signs your cooling tower needs attention

If you are seeing any of these, it is worth booking an inspection before the tower fails in peak season.

Rising approach temperature
The tower can no longer cool water to its design temperature, so chillers and process equipment work harder.

Scaled, fouled or sagging fill
Deposits and collapsed fill sheets block airflow and cut heat transfer.

Visible drift or mist carry-over
Worn or missing drift eliminators let water escape, wasting water and spreading spray around the site.

Noisy or vibrating fans and drives
Worn bearings, belts, gearboxes or motors, often the first sign of a breakdown.

Leaking casings or basins
Cracked or corroded panels and seals waste water and damage the structure around them.

Fill media: before and after

Cooling tower types we work on

Induced draft cooling towers
Fans on top of the tower draw air up through the fill. These are the most common towers on campuses, hospitals, commercial buildings and process plants. We replace fill, drift eliminators and spray nozzles, repair casings, and replace fan motors and drives.

Containerised cooling towers
Portable towers built into a container frame for temporary cooling, hire fleets and remote sites. We carry out full rebuilds, from structure and casing to fans, fill and pipework, and return them ready to deploy.

How a cooling tower job works

Inspection

Structure, fill, drift eliminators, motor, gearbox and water quality assessed, with a findings list.

Scope and quote

Fixed-scope quote covering parts, labour, access and outage time.

Shutdown planning

SWMS, permits, isolation planning and materials staged in Townsville.

Works

Refurbishment and component replacement, then recommissioning and a performance check.

What affects the cost of a cooling tower refurbishment

Every tower is different, so we quote after an inspection. These are the factors that move the price:

Tower size and type
Containerised or induced draft, and the number of cells and fans.

Scope of work
Fill, drift eliminators and nozzles only, or casing repairs and motor and drive replacement as well.

Access and cranage
Rooftop and hard-to-reach towers may need cranes, scaffolding or rope access.

Shutdown timing
Work inside a tight outage window, or after hours, takes more planning and labour.

Site requirements
Inductions, permits and isolation on mines and hospitals add set-up time.

Send us your tower details, or book an inspection, and we will give you a fixed-scope quote.

Cooling tower FAQs

What standard applies to cooling tower maintenance in Queensland?

AS/NZS 3666 sets out microbial control for building water systems, including cooling towers, alongside Queensland public health requirements for Legionella risk management. We plan and document our work to meet both. In Queensland, WorkSafe’s guide to Legionella control in cooling water systems sets out how owners should manage the risk.

How often should a cooling tower be inspected?

It depends on the tower, how it is used and the requirements that apply to your site. Most towers are inspected and sampled regularly through the year. We can review your tower and set up an inspection and maintenance schedule with you.

How much does a cooling tower refurbishment cost?

It depends on the tower size and type, what needs replacing, access and cranage, and shutdown timing. We inspect the tower first and then give you a fixed-scope quote.

When should cooling tower fill be replaced?

When it is scaled, fouled, sagging or broken, or when the tower can no longer hold its design approach temperature. An inspection tells you whether cleaning or replacement is the better option.

How long does a cooling tower refurbishment take?

It depends on the tower size and scope. We stage parts in Townsville before the outage so work happens inside your shutdown window. Your quote states the expected outage time.

Do you clean and disinfect cooling towers?

No. We carry out Legionella auditing and water sampling, and refurbish and repair towers. Cleaning and disinfection are usually handled by your water treatment provider.

What types of cooling towers do you work on?

We work on the two most common types of industrial and commercial cooling tower: induced draft towers, where fans pull air up through the tower, and forced draft towers, where fans push air in from below. Both come in counterflow and crossflow designs, and we also work on containerised (packaged) towers. We replace fill media, drift eliminators and spray nozzles, repair casings, and replace motors and drives.

Which areas do you service for cooling towers?

We refurbish and repair cooling towers Australia-wide from our Townsville base, including Townsville, Cairns, Mackay, Mount Isa, Cloncurry, the Bowen Basin and Gladstone. We also carry out cooling tower Legionella auditing in Brisbane, and can discuss projects in Papua New Guinea and Fiji.

Need a cooling tower inspection or shutdown?

Whether you have a shutdown coming, a compliance audit to prepare for, or ageing towers to upgrade, our Townsville team can help.
