A Fan Cylinder for Cooling Tower Applications can be designed differently based on:
-
Cooling tower capacity
-
Fan diameter
-
Fan operating speed
-
Cylinder diameter
-
Cylinder height
-
Fan-stack configuration
-
Material requirement
-
Environmental conditions
-
Installation arrangement
-
Access and maintenance needs
The size of the cylinders should not be taken as a standard size, but rather the basis for the cooling tower/fan layout.
What Is a Fan Cylinder?
A fan cylinder is a cylindrical structure, casing or cover installed around the fan discharge area of a cooling tower. It gives a fixed way for the air pumped by the fan to exit.
Mechanical cooling tower is the type of tower in which the fan is used to circulate or blow air through the tower and remove it vertically. The cylinder encloses the fan area and contributes to the forming of the discharge geometry.
In a fan-cylinder arrangement the following main elements are typically taken into account:
|

The final design should be confirmed using the cooling tower's engineering requirements.
How Does a Cooling Tower Fan Cylinder Work?
Fan Cylinder for Cooling Tower system helps in proper airflow discharge.
The fan operates during the cooling tower's operation, circulating air through the tower. The air flows through the fan, leaving the fan through the upper part of the tower. This is surrounded by the cylinder which defines a vertical path for the outgoing air.
A suitable cylinder can help:
-
Create a man-made fan discharge area.
-
Ensure that the fan assembly is well sealed.
-
Ensure adequate clearance around the rotating fan.
-
Facilitate the desired air flow pattern.
-
Make a part of the roof of the cooling tower.
-
Offer a practical connection point between fan system and other tower structure.
The cylinder should not be considered as a separate component to the fan, fan deck and tower structure. It must be the same size as the entire assembly.
FRP Fan Cylinder
An FRP Fan Cylinder is a product that is made from a composite material known as fibre-reinforced plastic. Because FRP can provide a desirable combination of low weight, corrosion resistance and structural properties, it is widely employed in cooling tower
components.
In applications in which moisture and constant exposure to cooling-system conditions are factors to consider, a FRP Fan Cylinder for Cooling Tower can be the right choice.
The main features of the FRP cylinders are listed below:
-
Lightweight construction
-
Good resistance to moisture
-
Corrosion-resistant characteristics
-
Suitable strength-to-weight ratio
-
It can be used in various industrial cooling applications.
-
Easy to handle in comparison to heavier metallic structures
-
Available in application specific sizes.
The performance of FRP, however, is a function of resin system, reinforcement, quality of manufacture, thickness and operating environment. Hence, care needs to be taken in specifying the material and assume that the performance of all the FRP cylinders is same.
Advantages of FRP Fan Cylinders
In some applications, such as cooling tower fan-cylinder, where a good corrosion resistance and manageable weight is required, FRP can be a practical material.
1. Resistance to Moisture and Corrosion
Cooling towers are continually faced with the elements of water, humidity and changing environmental conditions. FRP is not subject to the corrosion that occurs with traditional steel and is suitable for many wet operating conditions.
2. Lightweight Construction
FRP materials are relatively lighter and thus, easy to handle and install, especially in the case of a large cylinder.
3. Long-Term Application Potential
FRP components, if designed, manufactured and maintained correctly, can reliably serve in demanding cooling environments.
4. Lower Handling Requirements
Transportation, positioning and installation may be easier since FRP can be lighter than traditional metallic options.
5. Application Flexibility
The FRP cylinders can be produced based on the designed requirements based on the design and production capacity, as per the required dimension.
Limitations and Considerations
FRP is not always the most appropriate material for a cooling tower. Some considerations need to be taken into account before final choice.
|
Consideration
|
Why It Matters
|
|
Temperature
|
Excessive temperatures may affect resin performance
|
|
Structural loading
|
Cylinder design must withstand expected loads
|
|
UV exposure
|
Outdoor installations require appropriate material consideration
|
|
Impact
|
Handling and installation should avoid unnecessary impact
|
|
Dimensions
|
Oversized or undersized cylinders may not suit the fan assembly
|
|
Mounting
|
Correct support and fastening are essential
|
|
Manufacturing quality
|
Fibre distribution, resin system and workmanship influence performance
|
So, the selection of a FRP Fan cylinder for cooling tower should not just rely on the material but also on the actual working condition.
Applications of Fan Cylinders in Cooling Towers
A fan cylinder cooling tower configuration is typically used with mechanical cooling towers with induced draft and other cooling towers where air is blown up a stack.
Typical applications include:
Industrial Process Cooling
Cooling towers are employed to cool undesirable heat from circulating water in manufacturing or process plants. The air-discharge system comprises fan cylinders.
HVAC Cooling Systems
Mechanical cooling towers can be employed by large commercial and institutional cooling systems. Fan-cylinder assemblies can be added to upper fan portion.
Power and Energy Facilities
Large cooling towers with suitable fan-stacks can be employed in facilities that have significant heat rejection needs.
Chemical and Process Industries
The use of materials in tower components has become an important consideration when cooling systems are used non-stop in humid or chemically-induced environments.
Replacement and Refurbishment
Old cooling tower systems might need to be replaced due to deterioration, physical harm, corrosion of metal elements, or a change in the fan layout.
Cooling Tower Fan Cylinder Suppliers in India
SP Cooling Towers is an elite Cooling Tower Fan Cylinder Suppliers in India and can cater to the needs of new projects of cooling towers as well as replacement and maintenance applications.

Buying Guide for Cooling Tower Fan Cylinders
Buyers should gather the necessary technical data prior to ordering a Fan Cylinder for Cooling Tower. This helps to eliminate the chance for dimensional mismatch and makes comparison of products easier.
Check the Fan Diameter
The cylinder must fit with the fan assembly and offer the necessary clearance between the rotating parts.
Confirm Cylinder Dimensions
Avoid using terms for size like “large” or “small” when describing diameter and/or height.
Select the Material
For various cooling environments, FRP can be used to a certain extent, but the selection needs to take into account the conditions of the structure to be built, temperature, exposure, etc.
Review the Mounting Arrangement
The cylinder needs to connect properly with the fan deck or supporting structure.
Consider Operating Conditions
Material and construction requirements may be affected by temperature, humidity, chemical exposure, wind and outdoor exposure.
Ask for Technical Details
Technical information, such as drawings, dimensions, materials, etc. can be helpful for project and replacement needs to determine the appropriate product.
