The United States has one of the world's largest installed bases of industrial and commercial cooling towers. Power plants, refineries, chemical facilities, data centers, manufacturing plants, food-processing facilities, and HVAC systems all depend on cooling towers for efficient heat rejection.
Inside these towers, cooling tower fill plays a critical role. It increases the contact area between circulating water and air, allowing heat and moisture to transfer more efficiently. When fill becomes fouled, damaged, brittle, or deformed, replacing it can restore cooling performance without replacing the entire tower.
For retrofit projects, however, standard fill may not fit an existing tower. This is why many industrial buyers look for custom cooling tower fill manufacturers in the USA that can provide replacement media according to specific dimensions, materials, and operating conditions.
Below are five manufacturers and suppliers worth considering when sourcing custom cooling tower fill in the USA.
Custom cooling tower fill is fill media manufactured or configured to meet the requirements of a specific cooling tower.
Compared with standard products, custom fill can be specified according to:
Fill height
Module dimensions
Sheet thickness
Flute or corrugation pattern
Pitch
Specific surface area
PVC or PP material
Water loading
Operating temperature
Existing support structure
Custom fill is particularly valuable for cooling tower fill replacement, retrofit projects, and older towers where original fill is no longer available.
Power Tower Cooling Technology supplies cooling tower replacement components to industrial customers internationally, including buyers in the United States. Its product range includes custom cooling tower fill, PVC film fill, PP fill, splash fill, and other aftermarket cooling tower components.
The company can manufacture or configure replacement fill according to project dimensions and tower requirements. This can be useful for buyers looking for alternatives to original-brand replacement media.

When replacing fill in an existing Marley or SPX tower, verify the tower model, fill arrangement, water distribution system, and available installation space.
| Manufacturer/Supplier | Main Strength | Fill Applications | Customization |
|---|---|---|---|
| Power Tower Cooling Technology | Aftermarket customization | PVC, PP, film, splash fill | High |
| Brentwood Industries | Plastic fill technology | Film and splash fill | High |
| BAC | Cooling tower engineering | Engineered film fill | High |
| EVAPCO | Heat-transfer equipment | Replacement fill | High |
| SPX Cooling Technologies | Marley/SPX expertise | Industrial replacement fill | High |
Choosing a cooling tower fill manufacturer requires more than comparing prices. The replacement must provide the required thermal performance while fitting the existing tower.
PVC cooling tower fill is widely used for film-fill applications because it offers a good balance of heat-transfer performance, chemical resistance, durability, and cost.
PP cooling tower fill can be considered for applications requiring higher temperature resistance or particular chemical compatibility.
For water containing significant suspended solids, biological contamination, or debris, splash fill may be a better option because its open structure can reduce blockage problems.
Before ordering replacement fill, measure the existing product carefully.
Important specifications include:
Length and width
Fill height
Sheet thickness
Flute pitch
Module dimensions
Number of layers
Support configuration
Correct dimensions help ensure proper installation and water distribution.
U.S. cooling towers operate under a wide range of water conditions. Scale, corrosion products, suspended solids, biological growth, and process contamination can affect fill performance.
A fill supplier should understand the water chemistry and recommend a design appropriate for the application.
The selected fill material must withstand the actual hot-water temperature. PVC and PP have different thermal characteristics, so material selection should be based on real operating conditions.
A professional manufacturer should be able to provide information such as:
Fill material
Fill height
Specific surface area
Water loading
Air pressure drop
Temperature range
Sheet thickness
Fire-retardant properties
Installation requirements
This allows buyers to make a technical comparison rather than choosing solely on purchase price.
Original-brand fill is not always the only option for an existing cooling tower. Aftermarket cooling tower fill can be manufactured to match the tower when the replacement is properly engineered.
For a custom quotation, provide:
Cooling tower manufacturer and model
Existing fill dimensions
Fill height
Hot-water temperature
Cold-water temperature
Circulating water flow
Water-quality information
Photos of existing fill
Drawings or samples
Required quantity
The more complete the information, the easier it is for the manufacturer to recommend the correct fill.
Cooling tower fill has a direct impact on heat-transfer performance. Poorly selected or heavily damaged fill can reduce cooling capacity, increase pressure drop, and create maintenance problems.
Properly designed custom cooling tower fill can help:
Improve air-water contact
Maintain heat-transfer efficiency
Reduce unnecessary pressure drop
Support cooling tower capacity
Simplify retrofit projects
Extend tower service life
For older U.S. cooling towers, custom replacement fill can therefore be a practical alternative to major equipment replacement.
The best custom cooling tower fill manufacturer in the USA depends on your tower brand, application, water quality, operating temperature, performance requirements, and budget.
Brentwood, BAC, EVAPCO, and SPX offer extensive cooling tower and heat-transfer expertise, while aftermarket suppliers such as CoolingTowerPart.com can provide customized replacement options for different tower designs.
Before choosing a supplier, compare material, fill dimensions, thermal performance, water loading, pressure drop, customization capability, quality, and delivery time.
For U.S. industrial buyers, providing complete tower specifications and photographs is the most effective way to obtain an accurate quotation for PVC, PP, film, or splash cooling tower fill.
PVC is one of the most common materials for film fill because it offers good heat-transfer performance and cost efficiency. PP can be used when higher temperature resistance or specific chemical compatibility is needed.
Yes. Cooling tower fill can be manufactured or configured to match specific dimensions, fill height, material, thickness, pitch, and support requirements.
Yes, provided that the replacement fill is properly engineered for the tower's dimensions, water loading, airflow, operating temperature, and distribution system.
Fill should be replaced when it becomes severely fouled, damaged, brittle, deformed, or unable to maintain the required cooling performance.
Provide the tower brand and model, existing fill dimensions, fill height, operating temperatures, water flow, water quality, photos, drawings or samples, and required quantity.
