If you are sourcing cooling tower infills and drift eliminators, you already know that choosing the right supplier is about much more than finding the lowest price.
Cooling tower fill plays a major role in heat transfer, while drift eliminators help reduce water droplets escaping from the tower with the exhaust air. When either component is poorly selected, the result can be reduced cooling performance, higher water consumption, more frequent maintenance, or unnecessary replacement costs.
So, how do you find a supplier that actually fits your project?
In this guide, we introduce five companies with relevant capabilities in cooling tower infills, fill media, drift eliminators, and replacement components:
Power Tower Cooling Technology (Shaoxing) Co.,Ltd
Brentwood Industries
Baltimore Aircoil Company (BAC)
EVAPCO
ENEXIO
This is a practical buyer-oriented list rather than an official industry ranking. Each supplier has different product capabilities, manufacturing models, and application strengths. Your final choice should depend on your tower design, water quality, operating conditions, dimensions, and replacement requirements.
Cooling tower infills, also known as cooling tower fill or fill media, are the heat-transfer components installed inside an evaporative cooling tower.
Their basic job is simple: increase the contact area between water and air.
As hot water flows through the fill, the fill spreads the water into thin films or breaks it into smaller droplets. At the same time, air passes through the fill. Heat transfers from the water to the air, and a portion of the water evaporates.
There are two major approaches:
Film fill
Splash fill
Film fill uses sheets with specially formed surfaces to create thin water films and a large effective contact area. Splash fill uses bars, grids, or similar structures to repeatedly break falling water into droplets.
The right choice depends on your application. A highly efficient film fill may be excellent for relatively clean water, while an open splash-fill design can be more suitable where suspended solids or fouling are significant concerns.
Drift eliminators have a completely different role.
They are installed in the air-discharge path of a cooling tower and are designed to capture water droplets carried by the moving air.
Think of the cooling tower as having two important internal zones. The fill is the work area, where heat transfer takes place. The drift eliminator is the exit gate, helping keep valuable water inside the system before air leaves the tower.
Drift eliminators commonly use curved blades, corrugated sheets, or cellular structures. As the air changes direction through the eliminator, larger water droplets collide with the surfaces, combine into larger droplets, and drain back into the tower.
This can help reduce water loss, protect surrounding equipment, and limit unwanted water carryover.
At first glance, fill and drift eliminators may look like relatively simple plastic components.
But don't let their appearance fool you.
Their geometry, material, thickness, spacing, installation method, and compatibility with the tower can directly affect operating performance.
A well-designed fill system can help provide:
Better heat-transfer efficiency
Proper water distribution
Suitable air resistance
Longer operating life
Easier maintenance
Better resistance to fouling
Meanwhile, suitable drift eliminators can help:
Reduce water carryover
Minimize unnecessary water loss
Protect nearby equipment
Improve water retention
Maintain appropriate airflow conditions
That's why selecting a supplier should be treated as an engineering decision, not simply a commodity purchase.
Before comparing suppliers, define your application.
Ask yourself:
What type of cooling tower do I have?
What is the operating temperature?
How clean is the circulating water?
What are the existing fill dimensions?
Do I need OEM replacement or a compatible alternative?
Do I need both fill and drift eliminators?
The answers to these questions will narrow down your options quickly.
PVC is widely used for cooling tower film fill and drift eliminators because it offers a useful combination of chemical resistance, formability, durability, and cost effectiveness.
PP is another important material. Depending on the application, PP can offer different temperature and chemical-resistance characteristics.
For more demanding applications, specialized materials or formulations may be required.
Don't simply ask, “Is this PVC fill?”
Ask about the material grade, thickness, temperature range, geometry, and intended operating environment.
High surface area is useful, but it isn't the whole story.
Fill geometry influences water distribution, airflow, pressure drop, heat transfer, and fouling resistance.
For example, tightly packed film fill can provide excellent heat-transfer performance under suitable water conditions. However, if the circulating water contains a high concentration of suspended solids, those narrow passages may become fouled more quickly.
The best fill is therefore the one that maintains useful performance under your real operating conditions.
A fill designed for a counterflow tower should not automatically be installed in a crossflow tower.
The airflow and water-flow arrangements are different.
In a counterflow tower, air and water generally move in opposite directions. In a crossflow tower, air typically moves horizontally across the falling water.
These differences affect fill geometry, support arrangements, water distribution, and drift eliminator design.
This becomes particularly important when you are replacing old cooling tower components.
Maybe your tower has been running for 15 or 20 years.
Maybe the original fill is no longer available.
Maybe the manufacturer's original dimensions have changed.
Or perhaps you have a tower that was customized for a specific industrial process.
In these situations, a supplier that can manufacture according to drawings, dimensions, photographs, or samples can be much more useful than a supplier offering only standard products.
Power Tower Cooling Technology (Shaoxing) Co.,Ltd is the first supplier in this practical buyer's guide and is particularly relevant for customers looking for cooling tower fill, replacement fill, drift eliminators, and customized cooling tower internal components.
The company focuses on cooling tower components and replacement applications, offering solutions for different cooling tower configurations and project requirements.
Its product range can include:
PVC film fill
PP cooling tower fill
Counterflow fill
Crossflow fill
Splash fill
Customized fill blocks
Cooling tower drift eliminators
Spray nozzles
Fill support components
Cooling tower replacement parts
One advantage of working directly with a manufacturer is flexibility.
For example, imagine that your existing cooling tower has an unusual fill-block size. Instead of forcing a standard product into the tower, you can provide the existing dimensions and technical information and ask the manufacturer to develop a suitable replacement.
For customers sourcing cooling tower infills, Power Tower can provide different options based on the tower configuration and application.
PVC film fill is commonly considered where high contact area and efficient heat transfer are priorities.
PP fill may be considered when the application requires different material characteristics.
Splash fill can be useful for applications where fouling and suspended solids are important considerations.
The right product should always be selected according to water quality, temperature, airflow, tower structure, and required thermal performance.
Drift eliminators are another important part of the cooling tower internal package.
Power Tower can supply drift eliminator solutions for different cooling tower designs, including replacement applications.
For replacement projects, buyers should provide accurate dimensions and information about the existing tower. This can help ensure that the new eliminators match the available space and airflow direction.
Buying directly from a manufacturer can simplify communication.
You can discuss:
Product material
Fill dimensions
Sheet thickness
Flute geometry
Drift eliminator configuration
Custom sizes
Packaging
Production quantities
Replacement requirements
For international buyers, this can also make it easier to coordinate larger orders.
If you are sourcing cooling tower infills, drift eliminators, or replacement fill components, you can learn more about Power Tower Cooling Technology (Shaoxing) Co.,Ltd through its official website, coolingtowerpart.com.
Brentwood Industries is a global manufacturer of cooling tower components and offers a broad portfolio covering fill media, drift eliminators, splash fill, trickle fill, and other tower internals.
Its cooling tower product range includes solutions for both crossflow and counterflow applications.
Brentwood provides different fill geometries because different towers and water conditions require different approaches.
The company's portfolio includes film fills, trickle fills, and splash fills.
Film-fill designs can provide a large effective surface area for water-air contact. Other designs focus more heavily on maintaining larger flow passages and improving fouling resistance.
This is an important point for buyers.
You shouldn't select cooling tower fill simply because one product has a higher theoretical surface area. If your water contains significant suspended solids, a more open geometry may provide better long-term practicality.
Brentwood also supplies cellular and blade-style drift eliminators.
These products are designed to capture entrained water droplets while allowing air to continue moving through the tower.
For replacement applications, buyers should still verify dimensions, airflow direction, installation arrangement, and operating requirements before selecting a specific model.
You can review its current product information at Brentwood Industries.
Baltimore Aircoil Company (BAC) is an established manufacturer of evaporative cooling equipment and also provides replacement components and aftermarket solutions.
Its replacement portfolio includes cooling tower fill and drift eliminator products.
One useful feature of an OEM-oriented supplier is model-specific replacement support.
BAC offers replacement fill kits designed for specific cooling equipment and configurations.
Complete kits can include multiple components rather than only loose fill sheets.
This can be valuable when you want to reduce installation complexity.
Instead of purchasing fill from one supplier, drift eliminators from another, and support components from a third company, an engineered replacement package may allow you to coordinate the project more efficiently.
BAC also provides parts for non-BAC equipment in its aftermarket business.
This is particularly relevant to industrial buyers who have older cooling towers and are no longer able to source every component directly from the original supplier.
For any replacement project, however, compatibility should be verified using actual dimensions and equipment information.
You can find more information through Baltimore Aircoil Company.
EVAPCO is another major cooling equipment manufacturer with cooling tower fill and drift-eliminator solutions.
Its product portfolio includes factory-assembled and field-erected cooling equipment as well as replacement parts.
EVAPCO's EVAPAK fill uses PVC construction and is designed for cooling tower heat-transfer applications.
Different fill configurations are available for different operating conditions, and the company also provides replacement fill resources.
For buyers, the important point is to match the fill to the equipment rather than assume that every EVAPAK configuration is appropriate for every tower.
Drift eliminators are incorporated into EVAPCO cooling equipment and are also available as replacement components.
Their purpose is to reduce water droplets carried out of the tower by the exhaust air.
When replacing drift eliminators, pay attention to pressure drop, airflow direction, dimensions, material, and drainage arrangement.
More information is available from EVAPCO.
ENEXIO has significant experience in industrial cooling and power-sector applications.
Its cooling tower component portfolio includes fill systems, splash fill, trickle grid fill, drift eliminators, and nozzles.
This makes ENEXIO relevant for large industrial installations where cooling tower internals need to withstand demanding operating conditions.
Trickle grid and splash-fill technologies can be useful in applications where water quality is a major concern.
Industrial cooling water isn't always clean.
It may contain suspended solids, process contaminants, biological growth, or other substances that make tightly packed fill difficult to maintain.
In these situations, an open fill design can sometimes offer practical maintenance advantages.
ENEXIO also manufactures drift eliminators designed for industrial cooling applications.
For large projects, buyers should evaluate not only the eliminator material but also the aerodynamic characteristics, installation method, structural support, and required maintenance access.
You can learn more about the company through ENEXIO.
The easiest way to understand the difference is to look at their jobs.
| Component | Main Function | Typical Materials | Main Selection Factors |
|---|---|---|---|
| Cooling tower infill | Increase water-air contact and heat transfer | PVC, PP, other materials | Water quality, temperature, tower type, thermal duty |
| Drift eliminator | Capture entrained water droplets | PVC, PP and other plastics | Airflow, pressure drop, tower geometry, droplet capture |
| Splash fill | Break water into droplets | PP, PVC and other materials | Fouling, suspended solids, temperature |
| Film fill | Spread water into thin films | Mainly PVC/PP | Heat transfer, water quality, airflow |
So, while both components are inside the cooling tower, they solve different problems.
Choosing cooling tower fill should start with the operating environment.
Water quality is one of the biggest factors affecting fill life.
Potential problems include:
Scale
Algae
Sludge
Suspended solids
Oil contamination
Biological growth
Debris
If fouling is severe, highly compact film fill may require more frequent cleaning.
In such cases, a more open fill geometry may be worth considering.
Determine whether the tower is:
Crossflow
Counterflow
Forced draft
Induced draft
Mechanical draft
Natural draft
The fill and drift eliminators need to match the tower's internal airflow and water-flow arrangement.
Temperature should never be ignored.
Standard PVC may be suitable for many applications, but high-temperature cooling water can require specially designed materials or configurations.
Always compare the supplier's recommended operating range with your actual process conditions.
This is especially important for replacement projects.
Measure:
Fill height
Fill width
Fill depth
Block dimensions
Sheet thickness
Flute spacing
Drift eliminator dimensions
Support-grid dimensions
Photos are also helpful.
If possible, provide drawings or samples to the supplier.
A few accurate measurements can prevent a very expensive installation problem.
The cheapest fill isn't necessarily the lowest-cost solution.
If it clogs quickly, deforms under temperature, or doesn't provide the required thermal performance, you may spend more on cleaning, downtime, and replacement.
This is one of the most common mistakes.
A fill that works perfectly in clean HVAC water may not perform the same way in heavily contaminated industrial water.
PVC is a material category, not a complete product specification.
Different products can have different thicknesses, flute patterns, surface characteristics, dimensions, and manufacturing quality.
“Please quote cooling tower fill” isn't enough information for an accurate replacement quotation.
Give the supplier dimensions and application information whenever possible.
Some buyers focus entirely on fill replacement and forget to inspect the drift eliminators.
If the eliminators are damaged, brittle, cracked, or badly fouled, replacing only the fill may leave another weak point inside the tower.
Not every dirty fill needs immediate replacement.
Sometimes cleaning is enough.
But replacement becomes more appropriate when the fill has:
Severe scaling
Broken sheets
Deformed sections
Brittle material
Permanent blockage
Significant biological growth
Structural damage
Reduced cooling performance
Poor water distribution
You should also consider the age and maintenance history of the tower.
If the fill has been cleaned repeatedly but performance continues to decline, replacement may provide a more reliable long-term solution.
Drift eliminators should be inspected along with the fill.
Look for:
Cracks
Broken blades
Deformation
Missing sections
Heavy scaling
Blocked passages
Poor drainage
Loose installation
A damaged drift eliminator can reduce water retention and potentially affect airflow.
During a major tower overhaul, replacing deteriorated eliminators at the same time as the fill can sometimes make practical sense.
Not always—but it can simplify a project.
Imagine ordering:
Fill from Supplier A
Drift eliminators from Supplier B
Supports from Supplier C
Now you have three technical conversations, three sets of drawings, three production schedules, and potentially three shipments.
A manufacturer capable of supplying multiple tower internals can reduce this coordination burden.
This can be particularly useful for large replacement projects.
Both models can work.
A manufacturer may offer greater flexibility for custom dimensions, production quantities, material options, and OEM-compatible replacements.
A distributor may offer advantages such as local inventory, faster delivery, or installation support.
Before purchasing, simply ask:
“Do you manufacture this product, or do you source it from another factory?”
The answer can help you understand the supply chain and determine who will actually handle technical issues if something needs to be changed.
OEM replacement can be convenient when the tower is relatively new and exact model compatibility is important.
Compatible replacement can be attractive for older towers or projects where alternative sourcing is needed.
The important thing is to compare technical compatibility rather than choosing based only on the label.
Check:
Dimensions
Material
Thermal performance
Operating temperature
Water quality
Installation method
Pressure drop
Support structure
Expected service life
Before placing an order, ask your supplier these questions:
What fill material do you recommend?
Is the product designed for crossflow or counterflow towers?
What water quality can the fill handle?
What is the recommended operating temperature?
What are the exact fill dimensions?
What is the fill thickness?
What type of drift eliminator is recommended?
Can the components be customized?
Are replacement products available for older towers?
Can you provide drawings or installation information?
How are the products packaged for international shipping?
What information do you need to confirm compatibility?
A supplier that gives clear answers is usually easier to work with throughout the project.
Before contacting suppliers, prepare the following information:
Cooling tower information
Tower manufacturer
Model
Tower type
Capacity
Crossflow or counterflow
Number of cells
Operating information
Hot-water temperature
Cold-water temperature
Flow rate
Ambient conditions
Water chemistry
Suspended solids
Component information
Existing fill dimensions
Fill type
Material
Drift eliminator dimensions
Support-grid dimensions
Photos
Drawings
The more complete your information, the more accurate your quotation is likely to be.
For buyers specifically looking for cooling tower infills and drift eliminators supply, Power Tower offers the advantage of focusing on cooling tower components and replacement requirements.
Instead of treating fill as a generic plastic product, a replacement project can be discussed around the actual tower.
That means considering:
Tower configuration
Existing dimensions
Material selection
Water quality
Operating temperature
Fill geometry
Drift eliminator design
Installation requirements
This approach is particularly useful when you are replacing components in an existing tower rather than designing a completely new cooling system.
Finding the right cooling tower infills and drift eliminators supplier is ultimately about matching the component to the application.
Power Tower Cooling Technology (Shaoxing) Co.,Ltd provides cooling tower fill and drift eliminator solutions with a focus on replacement and customized component requirements.
Brentwood Industries offers a broad portfolio of engineered cooling tower internals.
Baltimore Aircoil Company (BAC) and EVAPCO combine cooling equipment manufacturing with OEM and aftermarket replacement capabilities.
ENEXIO brings extensive industrial and power-sector cooling experience.
There is no single cooling tower fill that is perfect for every tower.
The right product depends on water quality, tower configuration, temperature, airflow, dimensions, thermal requirements, and maintenance conditions.
So before you ask for a price, gather your measurements.
Before you compare suppliers, understand your water.
And before you order replacement fill, make sure you know whether you need film fill, splash fill, or another configuration.
That's how you turn a simple parts purchase into a successful cooling tower improvement project.
