Choosing the right fill for cooling tower applications can make a bigger difference than many buyers expect.
Cooling tower fill is not simply a plastic component sitting inside the tower. It is the working surface where air and water interact, allowing heat to move from the circulating water into the air. If the fill is poorly selected, damaged, clogged, or incompatible with the tower design, cooling performance can drop quickly.
But here is the tricky part: there are many cooling tower fill manufacturers and suppliers on the market. Some specialize in PVC film fill. Others offer PP fill, splash fill, replacement media, drift eliminators, or complete cooling tower components.
So, which suppliers deserve your attention?
In this guide, we introduce five cooling tower fill manufacturers and suppliers worth considering. We will also explain what each company offers, what type of application it may suit, and what you should check before ordering cooling tower fill.
Note: This is an editorial industry shortlist rather than a universal ranking. The best supplier for your project depends on your tower type, dimensions, water quality, thermal requirements, budget, and replacement requirements.
Before comparing suppliers, let's start with the product itself.
Cooling tower fill increases the contact area between water and air. As hot water travels through the fill, the fill helps spread or break up the water so that more water surface is exposed to the airflow.
The result?
Better evaporation, better heat transfer, and more effective cooling.
Think of cooling tower fill as the “engine room” of the wet section. The fan moves the air, the pump moves the water, but the fill creates the environment where the actual air-water heat exchange can happen.
There are several major categories, including:
Film fill
Splash fill
Trickle fill
Crossflow fill
Counterflow fill
PVC fill
PP fill
Replacement fill
The right choice depends heavily on the tower and application.
Before jumping into the Top 5 list, it helps to know what separates a good supplier from a poor one.
A reliable cooling tower fill manufacturer should ideally provide:
Suitable fill designs for different tower configurations
Consistent material quality
Accurate dimensions
Good thermal performance
Appropriate fouling resistance
Replacement compatibility
Technical support
Custom sizing when necessary
Stable production capability
Clear product specifications
Don't choose a supplier simply because its fill is the cheapest.
A cooling tower may run for years. A small difference in fill quality can become a much bigger difference in operating performance and maintenance cost.
If you are specifically looking for a supplier of fill for cooling tower, Power Tower Cooling Technology (Shaoxing) Co.,Ltd is a strong company to consider, particularly for cooling tower fill and replacement components.
The company focuses on cooling tower-related products and provides solutions for customers who need cooling tower fill, replacement media, and other cooling tower components.
For buyers who are replacing old fill, one important advantage is the ability to focus on the actual dimensions and configuration of the existing tower rather than simply buying a generic product.
One of the most important things when replacing cooling tower fill is compatibility.
The fill needs to fit the existing tower structure, water distribution system, airflow arrangement, and available fill volume.
A supplier familiar with cooling tower components can help buyers evaluate factors such as:
Fill height
Fill length
Fill width
Sheet thickness
Flute design
Material
Packing density
Installation method
Water quality
Tower configuration
This is particularly useful when you are working with an older cooling tower.
Replacement is one of the most common reasons buyers search for fill for cooling tower.
Over time, fill can become:
Brittle
Deformed
Clogged
Broken
Fouled
Damaged by chemicals
Reduced in thermal performance
When that happens, replacing the entire tower may not be necessary.
In many cases, replacing the fill can restore a significant portion of the tower's original heat-transfer capability.

Brentwood Industries is another well-known supplier of cooling tower fill and related components.
Its cooling tower product portfolio includes different types of film fill, trickle fill, splash fill, fill supports, and other cooling tower components.
The company emphasizes balancing thermal efficiency with fouling resistance, which is an important consideration because not every cooling tower operates with perfectly clean water.
Brentwood offers several film-fill configurations, including cross-fluted, herringbone, offset-fluted, vertical-fluted, and hybrid-fluted designs.
Different geometries create different air and water flow characteristics.
For example, cross-fluted designs are intended to promote water distribution and thermal performance, while vertical-fluted designs can be useful when fouling resistance is more important.
Splash fill can be particularly attractive for applications where water contains high levels of suspended solids or contaminants.
Instead of creating a continuous water film across a sheet, splash fill breaks the falling water into droplets.
That makes the design more tolerant of certain difficult water conditions.
Brentwood's current product information includes film fills, trickle fills, splash fills, and related support components.
SPX Cooling Technologies, through its Marley brand, is another major name in cooling tower technology and replacement components.
Its cooling tower parts portfolio includes a broad selection of film fills and splash fills for different tower configurations.
This is especially relevant when the project involves an existing Marley cooling tower or another application requiring engineered replacement components.
Marley's fill portfolio includes counterflow film fill, crossflow film fill, and several splash-fill designs.
For example, Marley MX is a crossflow film fill designed to spread water into a thin film across vertical surfaces.
The company also offers splash-fill products such as Omega, Mesa, Alpha III, Ladder, and other configurations.
Suppose you have an older crossflow tower.
You cannot simply purchase any film fill that looks similar.
The replacement needs to work with the existing:
Fill supports
Water distribution
Airflow
Fill depth
Tower geometry
Operating conditions
This is why experienced suppliers usually ask for the tower model, fill dimensions, photos, operating data, or drawings before recommending a replacement.
Baltimore Aircoil Company, commonly known as BAC, is another major manufacturer in the evaporative cooling industry.
BAC is particularly well known for cooling towers, evaporative condensers, and closed-circuit cooling equipment.
For users working with BAC equipment, the manufacturer's original specifications and replacement-component information can be important when evaluating cooling tower fill.
Original-equipment manufacturers have a major advantage: they understand the tower for which the fill was originally designed.
That can make OEM replacement particularly attractive when:
The tower model is known
The original fill is still available
Performance specifications must be maintained
The system has strict engineering requirements
The customer wants OEM compatibility
However, OEM replacement is not always the only option.
For older towers, an aftermarket cooling tower fill manufacturer may provide a compatible alternative, sometimes with different material, geometry, or performance characteristics.
EVAPCO is another established manufacturer in the evaporative cooling industry and is widely recognized for cooling towers, evaporative condensers, and related heat-transfer equipment.
For customers operating EVAPCO equipment, the first step should be identifying the exact tower model and existing fill configuration.
This is especially important because a tower's original fill system is part of a larger thermal design.
OEM suppliers can be a strong choice when you want:
Original specifications
Model-specific components
Factory engineering support
Known compatibility
Existing documentation
But if your tower is very old, it is worth comparing OEM and aftermarket alternatives.
Sometimes the best solution is not simply replacing the old fill with an identical product. A newer fill design may provide an opportunity to improve fouling resistance, maintenance, or thermal performance.
| Manufacturer / Supplier | Key Strength | Common Fill Focus | Suitable For |
|---|---|---|---|
| Power Tower Cooling Technology (Shaoxing) Co.,Ltd | Cooling tower fill and replacement solutions | Film fill, replacement fill and components | Replacement and cooling tower projects |
| Brentwood Industries | Wide fill technology portfolio | Film, trickle and splash fill | Industrial and commercial applications |
| SPX / Marley | OEM and aftermarket cooling tower components | Film and splash fill | Marley and various tower applications |
| BAC | Complete evaporative cooling systems | OEM cooling tower components | BAC equipment and replacement projects |
| EVAPCO | Evaporative cooling technology | OEM cooling tower components | EVAPCO systems and industrial applications |
The companies above have different strengths, so there is no universal winner.
Your project requirements should determine which supplier makes the most sense.
This is probably one of the most important questions buyers ask.
And the honest answer is:
It depends.
Film fill and splash fill solve the same basic problem—improving air-water contact—but they do it differently.
Film fill spreads water into thin layers across the surface of the fill sheets.
This creates a large surface area for heat transfer within a relatively compact volume.
Film fill can be highly effective when water quality is good.
Typical applications include:
HVAC cooling towers
Clean industrial process water
Commercial buildings
Chiller systems
However, film fill can be more sensitive to fouling and blockage.
Splash fill breaks falling water into droplets.
It is often considered when water contains more suspended solids, debris, or contaminants.
The open structure can help reduce the risk of plugging compared with some film-fill configurations.
For difficult water conditions, splash fill can be an attractive choice.
Material is another important consideration.
PVC is widely used for cooling tower film fill because it offers a practical combination of performance, manufacturability, chemical resistance, and cost.
PP, or polypropylene, may be selected for applications requiring different temperature or chemical-resistance characteristics.
But don't assume that PP is automatically better than PVC.
The correct material depends on:
Water temperature
Chemical exposure
UV exposure
Operating environment
Mechanical requirements
Expected service life
Project budget
A qualified supplier should evaluate the complete operating environment before recommending the material.
If your goal is replacing old fill, don't start by searching for the cheapest product.
Start by collecting information.
Find the nameplate.
Record:
Manufacturer
Model
Serial number
Year
Tower type
Measure the actual fill pack.
Record:
Length
Width
Height
Sheet thickness
Flute spacing
Pack configuration
Is it:
Film fill?
Splash fill?
Crossflow fill?
Counterflow fill?
Hanging fill?
Bottom-supported fill?
This information can dramatically narrow down your options.
Ask yourself:
Is the water clean?
Does it contain suspended solids?
Is scaling a problem?
Is biological fouling common?
Water quality should strongly influence the fill selection.
Don't forget temperature.
The supplier may need:
Entering water temperature
Leaving water temperature
Flow rate
Design wet-bulb temperature
These values help determine whether the proposed fill can meet the required thermal performance.
A good fill should do more than simply fit inside the tower.
It should provide an appropriate balance between:
Heat transfer + airflow + water distribution + fouling resistance + mechanical durability.
A fill with excellent thermal efficiency may not be suitable if it clogs every few months.
Likewise, a highly open splash fill may be robust but require more tower volume to achieve the same thermal duty.
The best design is the one that matches the application.
Two fill packs can look almost identical while having different flute geometry, surface area, sheet thickness, and thermal characteristics.
Never select fill based only on a photograph.
The replacement fill needs to fit the tower.
That sounds obvious, but dimensional compatibility is frequently overlooked.
Higher thermal efficiency does not automatically mean better real-world performance.
If the fill quickly becomes clogged, the theoretical advantage disappears.
Measure first.
Order second.
It is a simple rule that can prevent expensive mistakes.
The cheapest fill may not be the cheapest solution.
Consider:
Installation cost
Expected service life
Cleaning frequency
Energy consumption
Maintenance
Replacement intervals
Total cost matters more than purchase price.
Before placing an order, ask the supplier:
Is this fill suitable for my tower type?
Is it designed for crossflow or counterflow?
What material is used?
What is the sheet thickness?
What are the fill dimensions?
Is it suitable for my water quality?
What thermal performance can I expect?
Does it fit my existing support system?
Can you provide a sample?
Can you customize the dimensions?
What is the minimum order quantity?
What is the production lead time?
Can you provide technical drawings?
Do you offer replacement components?
What information do you need from me to confirm compatibility?
A professional supplier should be comfortable answering these questions.
There is no universal price for cooling tower fill.
The final cost can depend on:
Fill material
Fill type
Dimensions
Thickness
Surface area
Quantity
Packing method
Customization
Shipping distance
Project volume
For that reason, requesting a quotation based only on “I need cooling tower fill” is usually not enough.
Provide the tower dimensions and operating information whenever possible.
That gives the manufacturer a much better chance of quoting the correct product.
In many cases, yes.
Cooling tower fill is a replaceable component.
If the tower structure, fan system, basin, water distribution system, and other major components remain serviceable, replacing deteriorated fill may be a practical way to restore performance.
However, the decision should be based on an inspection.
If the tower has severe structural corrosion, damaged supports, failing mechanical equipment, or other major problems, fill replacement alone may not solve the underlying issue.
There is no single replacement interval.
Service life depends on:
Water quality
Chemical treatment
Operating temperature
UV exposure
Mechanical stress
Biological growth
Cleaning practices
Material quality
Some towers may operate for years before fill replacement is necessary, while towers exposed to aggressive conditions may require attention much sooner.
The best approach is regular inspection rather than replacing fill simply because it has reached a certain age.
For customers searching specifically for fill for cooling tower, Power Tower Cooling Technology (Shaoxing) Co.,Ltd is worth considering as a dedicated cooling tower component supplier.
The company focuses on cooling tower-related products and replacement solutions, making it relevant for customers who need to replace existing fill rather than purchase an entirely new cooling tower.
For replacement projects, the most useful information to provide includes:
Existing tower model
Fill dimensions
Fill photos
Tower type
Water flow
Water temperature
Existing fill type
Required quantity
The more information you provide, the easier it becomes to identify a suitable replacement.

Cooling tower fill increases the contact area between water and air, improving evaporation and heat transfer.
Without properly designed fill, the tower may not achieve its intended thermal performance.
There is no single best fill.
Film fill may be suitable for relatively clean water, while splash or other fouling-resistant designs may be better for water containing higher levels of suspended solids.
Yes. PVC is widely used for cooling tower fill because it offers a practical balance of performance, durability, chemical resistance, and cost.
However, the correct material depends on the application.
Start with the tower model, fill dimensions, tower type, water flow, entering and leaving water temperatures, and water quality.
Then ask a qualified supplier to confirm compatibility.
Many manufacturers can provide different dimensions, materials, thicknesses, flute configurations, and pack arrangements.
Customization is especially useful for replacement projects involving older or non-standard towers.
Choose based on your water quality and thermal requirements.
Film fill can offer high heat-transfer performance in suitable applications, while splash fill is often attractive where fouling resistance is a major concern.
The right fill for cooling tower applications is not necessarily the product with the highest advertised efficiency or the lowest price.
It is the product that works correctly inside your tower.
That means looking at the entire picture:
Tower type
Fill dimensions
Water flow
Water temperature
Wet-bulb temperature
Water quality
Fouling risk
Material
Installation method
Maintenance requirements
Long-term cost
Among the suppliers discussed in this guide, Power Tower Cooling Technology (Shaoxing) Co.,Ltd is a practical option for buyers specifically looking for cooling tower fill and replacement components, while Brentwood, SPX/Marley, BAC, and EVAPCO represent other established names in the broader cooling and evaporative-equipment industry.
The smartest approach is simple: measure first, understand your operating conditions, then choose the fill.
Don't let a low price or a good-looking product make the decision for you.
Cooling tower fill is too important to treat as just another spare part.
When correctly selected, installed, and maintained, the right fill can help your cooling tower transfer heat efficiently, operate reliably, and deliver the performance your system actually needs.
