Cooling tower fill is one of the most important components in a cooling tower because it provides the contact surface needed for efficient heat and mass transfer between circulating water and air. When the fill becomes damaged, blocked, brittle, or heavily fouled, cooling tower performance can decline significantly. For operators of Marley cooling towers in the UK, selecting the right Marley cooling tower fill replacement supplier is therefore essential for maintaining thermal performance, reducing operating costs, and extending equipment life.
The UK has a mature industrial cooling market serving power generation, manufacturing, chemical processing, food and beverage, HVAC, data centres, and commercial facilities. Buyers can source replacement fill directly from Marley/SPX or from specialist cooling tower companies offering compatible aftermarket products.
This guide reviews five notable Marley cooling tower fill replacement suppliers and sourcing options in the UK, with a focus on product capability, applications, replacement considerations, and purchasing factors.
Cooling tower fill operates continuously in a demanding environment. Over time, it can experience:
Scale accumulation
Biological fouling
Dirt and sediment blockage
Plastic degradation
Mechanical damage
High-temperature deformation
Reduced airflow
Uneven water distribution
Damaged or clogged fill reduces the effective contact area between air and water. As a result, the tower may experience higher cold-water temperatures and lower heat-rejection capacity.
Replacing the fill can restore the tower's thermal efficiency without necessarily replacing the complete cooling tower.
For many UK facilities, Marley cooling tower fill replacement is an economical alternative to complete tower replacement.
Power Tower Cooling Technology (Shaoxing) Co.,Ltd is a China-based cooling tower parts sourcing platform focused on replacement and aftermarket components for major cooling tower brands, including Marley, BAC, and EVAPCO.
For UK buyers looking for an alternative to domestic OEM sourcing, an international aftermarket supplier can be useful when cost, customization, and manufacturing flexibility are important.
Potential replacement solutions can include:
PVC film fill
PP film fill
Splash fill
Crossflow film fill
Counterflow film fill
Custom-sized fill
Fill support components
Drift eliminators
Cooling tower nozzles
One advantage of working directly with a manufacturer or specialized exporter is the ability to request customized dimensions.
Cooling tower fill replacement is not simply a matter of purchasing a generic sheet.
A supplier may need information such as:
Fill length
Fill width
Fill height
Sheet thickness
Flute pattern
Material
Operating temperature
Water quality
Tower type
Original fill model
For UK projects involving discontinued Marley tower models, custom manufacturing may provide a practical alternative.
SPX Cooling Technologies, the company behind the Marley cooling tower brand, is the first supplier UK operators should consider when original equipment compatibility is the highest priority.
Marley cooling towers are widely used in industrial and HVAC applications, and SPX provides replacement components and technical support for its equipment.
Depending on the cooling tower model, replacement components may include:
Marley film fill
Marley splash fill
Crossflow fill
Counterflow fill
Drift eliminators
Spray nozzles
Louvers
Fan components
Mechanical drive components
Water distribution components
One important advantage of sourcing through the original manufacturer is access to equipment-specific engineering information.
Original Marley fill can be particularly attractive when:
Exact OEM compatibility is required
The tower model and serial number are available
The facility needs documented technical support
The installation has strict engineering requirements
Thermal performance must match the original design
For older cooling towers, however, availability, lead time, and cost should be checked before placing an order.
Brentwood Industries is an established manufacturer of cooling tower fill and related heat-transfer products with an international presence.
Its cooling tower fill products are commonly considered for replacement and refurbishment projects where the customer requires engineered plastic fill rather than necessarily purchasing OEM-branded material.
Brentwood manufactures products for applications involving:
Film fill
Splash fill
Crossflow towers
Counterflow towers
Industrial cooling systems
HVAC cooling towers
Film fill uses closely spaced corrugated sheets to create a large surface area for water and air contact. Splash fill, in contrast, repeatedly breaks the water stream into droplets as it falls through the tower.
Brentwood-type fill can be considered for UK cooling tower refurbishment projects where engineers need to evaluate:
Existing fill dimensions
Sheet thickness
Flute geometry
Water loading
Airflow
Fouling conditions
Operating temperature
Tower configuration
A technical assessment should always be completed before selecting an aftermarket fill.
The UK cooling tower service market includes specialist companies that supply replacement components and carry out cooling tower refurbishment.
These companies can be useful for customers that require more than simply purchasing loose fill sheets.
A cooling tower specialist may provide:
Cooling tower inspection
Fill replacement
Fill cleaning
Spray nozzle replacement
Drift eliminator replacement
Fan maintenance
Gearbox inspection
Water distribution inspection
Tower refurbishment
Installation services
For facilities with limited maintenance personnel, purchasing cooling tower fill replacement and installation as one project can simplify the refurbishment process.
A supplier that understands tower installation can identify problems that may not be obvious from photographs or dimensions.
For example, poor thermal performance may not be caused entirely by old fill. Other possible causes include blocked nozzles, poor water distribution, excessive drift, damaged louvers, fan problems, or insufficient airflow.
The fifth sourcing category consists of specialist plastic manufacturers and cooling tower component suppliers that serve UK industrial customers through direct sales, distributors, or international export.
These suppliers can be especially useful when a facility needs non-OEM Marley cooling tower fill manufactured to existing dimensions.
Depending on the manufacturer, products may include:
PVC cooling tower film fill
PP cooling tower fill
High-temperature fill
Splash bars
Film fill packs
Drift eliminators
Cooling tower louvers
Nozzles
Fill support grids
This category is worth considering for large projects because bulk quantities can make international sourcing commercially attractive.
However, UK buyers should evaluate freight costs, import requirements, delivery schedules, technical documentation, and installation support.
Choosing the correct fill type is more important than choosing a supplier based only on price.
Crossflow cooling towers allow air to move horizontally through the fill while water flows downward.
Film fill increases the water-air contact area by distributing water over corrugated plastic sheets.
Advantages can include:
High effective surface area
Good thermal performance
Compact fill volume
Efficient water distribution
Suitable for many HVAC and industrial applications
In a counterflow tower, air moves upward while water flows downward.
Counterflow film fill is designed to maximize contact between the two streams.
It is commonly selected when the tower requires:
High thermal performance
Compact fill volume
Efficient heat transfer
Controlled water distribution
Splash fill breaks falling water into smaller droplets as water contacts successive splash bars or grids.
It can be advantageous for applications where water quality is challenging because larger passages can be less susceptible to blockage than closely spaced film fill.
However, the correct selection depends on tower design and thermal requirements.
The material used for replacement fill can significantly affect service life.
PVC is widely used for conventional cooling tower applications because it provides:
Good chemical resistance
Good mechanical properties
Cost effectiveness
Suitable thermal performance
Established cooling tower applications
Polypropylene can be preferable for applications involving higher temperatures or certain chemical environments.
Potential benefits include:
Higher temperature capability
Good chemical resistance
Strong durability
Suitability for demanding industrial environments
The correct material should be selected according to the cooling tower's operating conditions rather than price alone.
Before ordering replacement fill in the UK, buyers should evaluate several technical factors.
Record the:
Marley model
Serial number
Tower dimensions
Cell configuration
Installation year
This information helps the supplier determine the original design.
Measure:
Length
Width
Height
Pack configuration
Sheet thickness
Even a small dimensional difference can create installation problems.
Determine whether the tower uses:
Film fill
Splash fill
Crossflow fill
Counterflow fill
Do not assume that all Marley towers use the same fill.
The fill material must withstand the actual operating temperature.
If the cooling tower operates at elevated temperatures, PP or another high-temperature material may be more appropriate than standard PVC.
Water containing high levels of:
Calcium
Silica
Suspended solids
Organic matter
Biological contaminants
can accelerate fill fouling.
In these applications, fill geometry and cleaning requirements should be considered carefully.
The total replacement cost varies significantly depending on tower size and project complexity.
Important cost factors include:
| Cost Factor | Impact |
|---|---|
| Tower size | Determines quantity of fill |
| Fill material | PVC and PP have different costs |
| Fill geometry | Affects manufacturing cost |
| OEM vs aftermarket | OEM products may cost more |
| Shipping | Important for imported products |
| Installation | Labour can significantly affect total cost |
| Tower access | Difficult access increases installation time |
| Water distribution | Nozzle replacement may add cost |
| Fill supports | Damaged supports may require replacement |
For an accurate quotation, suppliers normally need drawings, photographs, dimensions, quantities, and the cooling tower model.
One of the most important decisions is whether to purchase OEM Marley fill or a compatible aftermarket alternative.

The cheapest fill is not necessarily the most economical solution. Poorly matched fill can reduce cooling capacity and increase maintenance costs.
Replacing cooling tower fill should generally be treated as an engineering maintenance project.
Before installation:
Shut down the cooling tower.
Isolate electrical equipment.
Drain or isolate the relevant water system.
Remove damaged fill.
Inspect fill supports.
Inspect spray nozzles.
Clean the basin.
Verify water distribution.
Install replacement fill.
Check pack alignment.
Inspect drift eliminators and louvers.
Restart and monitor performance.
The exact procedure should follow the tower manufacturer's maintenance requirements and site safety procedures.
Mineral scale reduces the effective heat-transfer area and restricts water flow.
Algae, biofilm, and other deposits can block fill passages and reduce airflow.
Long-term exposure to ultraviolet radiation, chemicals, and heat can degrade plastic components.
Incorrect cleaning methods, impact, freezing, or structural movement can damage fill packs.
Blocked or damaged nozzles can leave portions of the fill dry while overloading other areas.
Marley cooling towers are used in many demanding applications, including:
Manufacturing plants
Power and energy facilities
Chemical processing
Food and beverage plants
Pharmaceutical facilities
Commercial HVAC systems
Data centres
District cooling systems
For these facilities, maintaining the designed approach temperature can be critical.
A fill replacement project may therefore deliver benefits such as:
Improved heat rejection
Lower cold-water temperature
Better energy efficiency
Improved airflow
Reduced maintenance
Extended cooling tower service life
Before purchasing replacement fill, UK buyers should collect:
Cooling tower manufacturer
Tower model
Serial number
Tower type
Fill type
Fill dimensions
Existing fill photographs
Quantity required
Operating temperature
Circulating-water flow
Water quality information
Current cooling performance
Delivery location
Required delivery date
Providing this information allows suppliers to prepare a more accurate quotation.
Marley cooling tower fill is the heat-transfer media installed inside a Marley cooling tower. It increases the contact area between circulating water and air, allowing heat to transfer from the water to the atmosphere.
Yes, compatible aftermarket fill can be used in many cooling tower refurbishment projects. However, dimensions, material, geometry, water loading, airflow, and thermal performance should be verified before installation.
Service life varies according to water quality, operating temperature, UV exposure, chemical treatment, cleaning practices, and tower operating conditions. Regular inspection is essential.
Neither material is universally better. PVC is commonly used for standard applications, while PP may be preferable for certain higher-temperature or chemically demanding applications.
Start with the Marley cooling tower model and serial number. Then verify fill dimensions, geometry, material, and installation configuration with the supplier.
Sometimes. If the fill remains mechanically sound and deposits can be removed without damaging the sheets, cleaning may restore performance. Severely damaged, brittle, deformed, or permanently blocked fill generally requires replacement.
Send the tower model, photographs, fill dimensions, quantity, operating temperature, water flow, and any available original drawings or specifications.
Selecting the right Marley cooling tower fill replacement supplier in the UK requires more than comparing prices. The replacement fill must match the tower's geometry, water loading, airflow, operating temperature, and water chemistry.
SPX Cooling Technologies/Marley is the natural choice when OEM compatibility and manufacturer support are priorities. Companies such as Brentwood Industries, UK cooling tower service specialists, and international aftermarket manufacturers can provide additional sourcing options, particularly when customers need competitive pricing, custom dimensions, or replacement solutions for older towers.
For UK industrial and commercial facilities, the best approach is to compare OEM and compatible alternatives based on thermal performance, material, service life, compatibility, installation requirements, delivery time, and total project cost.
A correctly engineered Marley cooling tower fill replacement can restore heat-transfer performance, improve cooling efficiency, and extend the useful life of the cooling tower without requiring complete equipment replacement.
