Switzerland is known for demanding engineering standards, energy-efficient industrial systems, and high-quality HVAC infrastructure. Cooling towers are used in a wide range of applications, including commercial HVAC, manufacturing, power generation, process cooling, and data-center cooling.
Among all cooling tower components, cooling tower fill is one of the most important. It increases the contact area between water and air, allowing more effective heat and mass transfer. The right fill can improve thermal performance while reducing fouling, pressure drop, maintenance frequency, and replacement costs.
However, the Swiss market is somewhat different from larger cooling-tower markets. Many companies serving Switzerland are not dedicated local fill manufacturers; instead, they are cooling-tower OEMs, engineering companies, component suppliers, or international manufacturers with European distribution networks. Industry sources identify companies such as Brentwood Industries, SPX Cooling Technologies, BAC, and Hamon among suppliers active in the Swiss market.

Swiss cooling systems often operate under strict requirements for efficiency, reliability, noise, water consumption, and environmental performance.
A cooling tower filler provides a large wetted surface where circulating water meets moving air.
Film fill spreads water into thin layers across corrugated PVC or PP sheets. It offers a high effective surface area and is commonly selected for relatively clean water applications.
Splash fill breaks water into droplets as it flows through grids, bars, or other structures. It is often preferred where water contains suspended solids or where resistance to fouling is important.
When purchasing cooling tower fill for a Swiss project, buyers should consider:
Cooling tower type
Counterflow or crossflow configuration
Water temperature
Water quality
Required thermal performance
Airflow resistance
Material compatibility
Fire-performance requirements
UV and chemical resistance
Replacement dimensions
Local installation conditions

For industrial facilities, fill selection may need to account for:
High circulating-water temperature
Chemical exposure
Suspended solids
Scaling
Biological fouling
Long operating cycles
Hamon is therefore particularly relevant for larger industrial and engineered cooling projects.
JAEGGI is a Swiss-based company known for hybrid cooling and heat-exchanger technologies.
It is important to distinguish JAEGGI from conventional PVC cooling tower fill manufacturers. Its strength is hybrid cooling and heat-exchange engineering, rather than being primarily a mass-market cooling tower fill producer.
Swiss cooling projects increasingly consider hybrid and energy-efficient approaches.
JAEGGI's presence illustrates an important trend: not every cooling project requires a conventional evaporative cooling tower with standard film fill.
Hybrid systems may be considered when the project prioritizes:
Reduced water consumption
Seasonal operating flexibility
Energy efficiency
Compact installation
Environmental performance
Swiss industrial and commercial users can therefore evaluate cooling tower fill alongside alternative heat-rejection technologies.
Gohl-KTK is another relevant name in the Swiss cooling market.

More demanding chemical environments
Applications requiring greater material flexibility
Some cooling tower manufacturers specify PP fill for elevated-temperature conditions; one manufacturer, for example, describes PP fill for continuous operation around 80–90°C depending on the model and operating conditions.
The choice between film and splash fill depends heavily on water quality.
Film fill offers high heat-transfer surface area.
Clean circulating water
HVAC cooling
Commercial buildings
Data centers
Industrial systems with effective water treatment
Splash fill is designed to repeatedly break water into droplets.
Fouling-prone water
Higher suspended solids
Wastewater-related cooling
Certain industrial processes
Applications where easy cleaning is important
SPIG, for example, describes splash-fill products for water that is prone to clogging, including sea and geothermal water.
Selecting a cooling tower filler should begin with operating conditions rather than price.
Determine whether the tower is:
Crossflow
Counterflow
Open circuit
Closed circuit
Mechanical draft
Natural draft
The airflow and water-distribution patterns determine the appropriate fill geometry.
Water quality is one of the most important fill-selection factors.
Film fill can provide excellent heat-transfer performance.
Splash fill or larger-flute film fill may be more appropriate.
The most common options include:
| Material | Typical Strength | Common Application |
|---|---|---|
| PVC | Cost-effective, good thermal performance | HVAC and general cooling |
| PP | Higher temperature capability | Industrial cooling |
| CPVC | Higher-temperature applications | Specialized process cooling |
| FRP | Structural and specialized applications | Heavy-duty systems |
Before placing a cooling tower fill order, collect the original tower information.
Ask the supplier for:
Tower model
Manufacturer
Fill type
Fill dimensions
Fill thickness
Module height
Module width
Flute type
Water temperature
Circulating-water flow
Heat load
Water quality
Photos of the existing fill, support grid, water distribution system, and tower interior can also help suppliers identify the correct replacement design.
Replacement becomes necessary when fill is damaged, deformed, clogged, scaled, or unable to provide the required thermal performance.
Look for:
Broken fill sheets
Collapsed modules
Excessive scaling
Mud accumulation
Biological growth
Increased approach temperature
Reduced cooling capacity
Uneven water distribution
Two fill packs may have similar dimensions but significantly different flute structures and thermal characteristics.
The correct replacement should match the thermal duty, water loading, airflow, and tower geometry.
The Swiss market is likely to place increasing emphasis on efficiency and lifecycle cost.
Modern cooling tower fill focuses on achieving greater heat-transfer performance without creating excessive pressure drop.
Better fill design can help optimize the balance between:
Heat-transfer area
Air resistance
Fan power
Water distribution
Cooling capacity
Sustainability is becoming an increasingly important purchasing consideration.
Future cooling tower fill solutions may place greater emphasis on:
Longer service life
Recyclable polymers
Lower material consumption
Reduced water consumption
Easy replacement
Modular design
Switzerland has a relatively specialized cooling-tower market. Industry listings show only a small number of companies categorized specifically under wet cooling towers in the country.
This means Swiss customers may purchase cooling tower fill through:
Local engineering companies
Cooling tower OEMs
European distributors
International fill manufacturers
Specialized replacement-part suppliers
For large projects, international sourcing can offer a wider selection of cooling tower fills types, materials, and customized dimensions.
