Cooling tower fill, also called cooling tower packing or heat-transfer media, is installed inside a wet cooling tower to increase the contact area between water and air.
In a typical film-fill system, warm circulating water flows over corrugated plastic sheets while air passes through the media. The increased surface area promotes heat and mass transfer, allowing evaporation to remove heat from the circulating water.

Common replacement materials include PVC film fill and polypropylene (PP) fill. Splash-fill configurations may also be appropriate for selected applications.
The correct replacement depends on the original tower design and actual operating conditions.
Cooling tower fill gradually loses performance when its passages become blocked or its structure deteriorates.
Increasing cold-water temperature
Higher cooling tower approach
Reduced heat-transfer capacity
Higher fan power consumption
Excessive airflow resistance
Heavy mineral scaling
Persistent biological fouling
Cracked fill sheets
Collapsed or deformed modules
Chemical degradation
Uneven water distribution
In some cases, cleaning can restore the original performance. If the fill remains structurally sound, professional cleaning may be more economical.
However, fill that has become brittle, cracked, permanently deformed, chemically damaged, or severely blocked usually requires replacement.
For customers that prioritize OEM compatibility, the first option should be to investigate EVAPCO's official sales and service channels and determine what support and supply options are currently available for the specific Russian installation.
EVAPCO is a major manufacturer of evaporative cooling and heat-transfer equipment. Its cooling towers are used in industrial and commercial applications worldwide.
OEM sourcing can be particularly valuable when a facility needs replacement media that closely follows the original tower design.
Customers should provide the exact model and serial number when requesting replacement information.

Fill manufacturer
Exact fill profile
Material
Temperature rating
Dimensional tolerance
Technical documentation
Warranty
Delivery schedule
A distributor should be able to explain how the proposed replacement media matches the original application.
Specialist manufacturers of cooling tower fill represent another option for Russian industrial customers.
Manufacturers commonly produce PVC and PP film fill for counterflow and crossflow cooling towers, as well as splash-fill products.
A specialist manufacturer may supply:
PVC film fill
PP film fill
High-temperature fill
Splash fill
Custom-size modules
Replacement fill blocks
Industrial heat-transfer media
Direct factory sourcing can be particularly attractive for large cooling tower projects.
Depending on the manufacturer, buyers may specify:
Fill block length

However, customization should be based on the cooling tower's engineering requirements rather than dimensions alone.
Ask for:
Product datasheet
Material specification
Technical drawing
Fill profile
Temperature rating
Chemical-resistance information
Dimensional tolerances
Packing specifications
Installation instructions
Quality documentation
For large industrial projects, obtaining samples or dimensional drawings before mass production can reduce compatibility risks.
A local cooling tower maintenance contractor can be a practical option when the project involves both replacement fill and installation.
Instead of purchasing the media separately, the contractor can manage inspection, removal, procurement, installation, and commissioning.
A specialist contractor may provide:
Cooling tower inspection
Fill condition assessment
Fill cleaning
Old-fill removal
Replacement-fill procurement
New-fill installation
Nozzle inspection
Water-distribution inspection
Drift eliminator replacement
Fan inspection
Motor inspection
Basin cleaning
Performance testing
Russian industrial facilities can have large cooling towers with difficult access and demanding shutdown requirements. A contractor with suitable lifting equipment and installation experience can reduce project-management complexity.
When selecting a contractor, request references, previous EVAPCO-related projects, fill specifications, installation procedures, safety documentation, and warranty terms.
The replacement fill should be selected according to the cooling tower's thermal and hydraulic requirements.
PVC film fill is widely used in wet cooling towers because it provides a large effective heat-transfer area.
High surface area
Lightweight construction
Efficient water spreading
Good heat-transfer performance
Cost-effective
Widely available
PVC film fill is suitable for many commercial and industrial applications when water quality and temperature remain within the product's specified limits.
Polypropylene fill can be considered for applications where greater chemical resistance or temperature capability is required.
Good chemical resistance
Durable polymer construction
Suitable for demanding industrial environments
Higher temperature capability for many product designs
Actual temperature limits vary by product, so buyers should always review the manufacturer's technical data.
Film fill distributes water into thin layers across corrugated sheets.
It provides a large contact area in a relatively compact volume and can deliver strong heat-transfer performance.
However, narrow passages may be susceptible to blockage from:
Scale
Suspended solids
Sludge
Biological deposits
Good water treatment and filtration are therefore important.
Splash fill repeatedly breaks water into droplets as it moves through the media.
It can be useful for selected applications where fouling resistance and water quality are important considerations.
However, film fill should not be replaced by splash fill without evaluating the tower's thermal and hydraulic design.
Russia's large power-generation sector uses cooling systems for thermal power facilities and other energy infrastructure.
Cooling tower fill must provide reliable heat rejection under extended operating periods.
Replacement projects should be planned around maintenance outages whenever possible.
Chemical and petrochemical facilities can place demanding requirements on cooling water.
Water chemistry, elevated temperatures, suspended solids, and chemical exposure should all be considered when selecting replacement fill.
PP may be considered in some demanding environments, but product-specific chemical compatibility must be verified.
Steel mills and metal-processing facilities use cooling water for production equipment, furnaces, compressors, and auxiliary systems.
These environments can generate dust and suspended solids, making water treatment and fill inspection especially important.
Refineries and related oil and gas facilities rely on cooling systems to remove process heat.
Cooling tower fill in these applications should be selected according to process temperature, circulating-water chemistry, and contamination conditions.
Food-processing facilities use cooling towers for process cooling, refrigeration, and HVAC.
Biological fouling and mineral scaling can reduce fill performance, so regular water treatment and inspection are important.
Large office buildings, hotels, shopping centers, hospitals, and mixed-use developments may use water-cooled chillers.
Maintaining cooling tower fill can help support suitable condenser-water temperatures during periods of high cooling demand.
Data centers require reliable heat rejection and carefully managed maintenance schedules.
For these facilities, fill replacement should be planned in advance to minimize downtime and maintain cooling-system redundancy.
Start with the nameplate and record:
Model number
Serial number
Tower type
Number of cells
Installation year
This information provides the supplier with a starting point for compatibility verification.
Record:
Length
Width
Height
Block quantity
Sheet thickness
Fill profile
Module arrangement
Support configuration
Take detailed photographs before removing the old media.
Temperature compatibility is critical.
The supplier should confirm that the proposed fill is suitable for the maximum water temperature of the application.
Important parameters include:
Water hardness
Suspended solids
Chlorides
pH
Biological activity
Chemical treatment
Scaling tendency
Poor water treatment can significantly reduce fill service life.
If the cooling tower handles dirty water, a highly compact film-fill configuration may be more vulnerable to blockage.
The replacement design should be selected according to actual operating conditions.
Changing the fill profile can affect airflow resistance.
A replacement product should provide the required thermal performance without creating unnecessary fan energy demand.
For Russian industrial projects, request appropriate technical documentation, including:
Datasheets
Drawings
Material specifications
Installation instructions
Performance information
Warranty terms
For imported products, compare:
Product price + packaging + freight + customs/import costs + domestic delivery + installation + downtime
The lowest product price does not necessarily produce the lowest total project cost.
International purchases involving Russia can be affected by changing customs rules, export controls, payment restrictions, sanctions, and transportation availability.
Buyers should independently verify current requirements with qualified customs, legal, logistics, and financial professionals before placing an international order.
A complete RFQ should include:
EVAPCO model
Serial number
Tower type
Existing fill dimensions
Fill profile
Material
Photographs
Water temperature
Water flow
Water chemistry
Required quantity
Delivery location
Required delivery date
Installation requirements
For large projects, request a technical drawing before approving production.
Potentially, yes. Compatible aftermarket fill is available for many cooling tower applications, but the replacement should be technically evaluated before installation.
Dimensions, fill profile, material, water loading, airflow, temperature, and thermal performance all need to be considered.
Neither material is universally better.
PVC is widely used for standard film-fill applications because of its heat-transfer performance and cost. PP may be preferred for selected high-temperature or chemically demanding applications.
The correct choice depends on the actual operating conditions.
There is no fixed replacement interval.
Service life depends on water quality, temperature, chemical exposure, biological control, cleaning practices, airflow, and mechanical conditions.
Routine inspection should determine whether cleaning or replacement is necessary.
Sometimes.
If the fill remains structurally sound, professional cleaning may remove deposits and restore performance.
If the fill is cracked, brittle, collapsed, chemically damaged, or permanently blocked, replacement is generally more appropriate.
It may be possible, but this requires technical evaluation.
The replacement must meet the tower's thermal, hydraulic, structural, and temperature requirements.
Yes. Specialist manufacturers can often produce custom-size fill blocks or modules.
Accurate measurements, photographs, and engineering information are important.
The most useful information includes the EVAPCO model and serial number, existing fill dimensions, fill profile, material, operating temperature, water flow, water chemistry, photographs, quantity, and delivery location.
Selecting an EVAPCO cooling tower fill replacement supplier in Russia requires careful evaluation of technical compatibility, material performance, water quality, logistics, and installation requirements.
The five main sourcing options covered in this article are EVAPCO's official channels, CoolingTowerPart.com, Russian industrial distributors, specialist cooling tower fill manufacturers, and local cooling tower maintenance contractors.
OEM channels may be preferable when original-equipment specifications and model-specific support are the priority. Aftermarket specialists can provide custom-size and alternative replacement solutions, while local distributors and contractors can simplify procurement, installation, and maintenance.
For Russian industrial facilities, buyers should pay particular attention to operating temperature, water chemistry, scaling, suspended solids, fill profile, airflow resistance, and project downtime. For imported products, current customs, trade, transportation, payment, and regulatory requirements should also be confirmed before ordering.
The best replacement fill is not necessarily the cheapest product. It is the product that provides the required thermal performance, dimensional compatibility, service life, and total project value for the specific EVAPCO cooling tower.
