Cooling Tower Replacement Parts by Model | Cooling Tower Systems

We stock replacement parts for every cooling tower we have built, including towers installed decades ago. Fill media, fan motors, drift eliminators, fan assemblies, spray nozzles, float valves, and basin hardware — all manufactured or specified to fit the original tower.

The fastest way to get the right part is to start with your model number. This page walks through how to find it, what fits your tower, and what to do if the nameplate is long gone.

Why the model number matters

Cooling tower parts are not universal. Fill pack dimensions, fan diameter, motor horsepower and pole count, and nozzle spacing all vary between models. A fill pack that fits a Model T-230 will not fit a Model T-280, and a motor with the right horsepower but the wrong pole count will run the fan at the wrong speed and move the wrong volume of air.

Ordering the wrong part costs you twice: once for the part, and again for the shutdown you scheduled to install it. Five minutes finding the model number saves both.

Step 1 — Find your model number

Every CTS cooling tower carries a nameplate with the model number stamped or printed on it. [CONFIRM WITH CTS: state exactly where the plate is located, e.g. "on the fan deck adjacent to the motor junction box".]

The model number follows a consistent format: the letter T, a dash, then the number. T-260. T-2100. T-3000. The number encodes the tower's nominal capacity, so a T-260 is a 60-ton tower and a T-2100 is a 100-ton tower.

Write it down before you go back inside. It is the one piece of information that makes everything else straightforward.

Step 2 — Go to your model's parts page

Each model has its own parts page listing every component that fits that specific tower, with part numbers and current pricing.

Cannot find your model number?

This happens more often than you would think. Nameplates fade in the sun, get painted over during facility maintenance, corrode away, or fall off entirely. On a tower that has been running for twenty years, a missing plate is normal.

We can usually identify your tower from physical characteristics instead. Send us as many of these as you can:

• Overall dimensions — diameter and overall height. These alone often narrow it to one or two models.
• Fan diameter — measure across the fan opening
• Inlet and outlet connection size — 2″, 3″, 4″, 6″, and whether they are threaded or flanged
• Motor nameplate — the motor carries its own plate with horsepower, voltage, phase, RPM and frame size. This is usually still readable even when the tower plate is not.
• Basin capacity — approximate gallons, if you know it
• Photos — a wide shot showing the whole tower, a shot of the piping connections, and one looking down into the tower from the fan deck

Send those to us and we will tell you what you have and what fits it. If we built it, we can identify it. Contact us here or call 800-752-1905.

Parts we supply

Fill media

The most commonly replaced part on any cooling tower, and the one most often responsible when a tower stops holding temperature. Fill is where heat transfer actually happens — water spreads across the media, air passes through, and evaporation carries the heat away. Over time fill fouls with mineral scale and biological growth, and eventually the packs sag or collapse.

How to tell if your fill needs replacing

Fan motors and drives

Motors in cooling tower service face constant moisture, warm humid air, and long duty cycles. They are a wear item. We supply replacement motors matched to your model's horsepower, voltage, phase, frame size and pole count — all of which have to match, not just the horsepower.

Motor and drive replacement guide

Drift eliminators

Drift eliminators capture water droplets before they leave with the exhaust air. When they degrade, you lose treated water to the atmosphere. The first sign is usually a rising water bill rather than anything you can see, though heavy drift is visible as mist above the tower.

Fans and fan assemblies

Complete fan assemblies and individual blades. Fan pitch affects both airflow and motor load, so replacement blades have to match the original specification — a wrongly pitched fan either moves too little air or overloads the motor.

Water distribution

Spray nozzles, distribution piping, and headers. Clogged or missing nozzles create dry spots in the fill where no cooling happens and scale forms fastest. Nozzles are inexpensive and are worth checking any time the tower is open.

Basin hardware

Float valves, strainers, drain fittings, and overflow connections. A stuck float valve is a common and easily fixed cause of high water consumption.

Winterization equipment

Immersion heaters and basin heater kits for towers operating through freezing weather. We supply both screw-type heaters with thermostats and bottom-mount heaters with control panels.

What to keep on the shelf

If unplanned downtime is expensive for your operation, a small parts inventory pays for itself the first time you need it. The items worth stocking are the ones that fail without warning and have the longest lead times:

• A spare fan motor, if your process cannot tolerate a shutdown
• A set of spray nozzles — cheap, small, and they clog
• Belts, if your tower is belt driven
• A float valve

Fill and drift eliminators are better ordered when needed, since they are bulky and their replacement is planned work rather than an emergency.

Repair or replace the whole tower?

Most parts are worth replacing on their own. A motor, a set of nozzles, a float valve — straightforward decisions.

It gets harder when several things are due at once. If you are looking at new fill, a new motor, new drift eliminators and a basin that is starting to corrode, the total can approach the cost of a new tower — and you will have spent that money on a structure that is still twenty years old.

A reasonable rule of thumb: if the parts needed exceed roughly half the cost of a replacement tower, or if the structure itself is failing, replacement usually makes more sense.

Work through our diagnostic guide to see the full picture before you commit either way. Or call us — we would rather sell you a motor than a tower you do not need.

Frequently asked questions

Do you stock parts for older CTS towers?

Yes. We have been manufacturing since 1971 and we supply parts for towers installed decades ago. Send us the model number, or the identifying details above if the nameplate is gone.

Can I use parts from another manufacturer?

Some components are interchangeable and some are not. Fill pack dimensions, fan pitch, and motor pole count are specific to the tower's design, and substituting changes how the tower performs. If you are considering a non-original part, call us first and we will tell you honestly whether it will work.

How do I know if a part is still under warranty?

Send us the model number and approximate installation date and we will check. See our warranty terms.

Can you help identify what is wrong with my tower?

Yes. Describe the symptom and send a photo if you can. Our troubleshooting guide covers the common problems, and if it is not obvious from that, call us.
