WST Series FRP Square Cooling Towers
When an industrial process generates excess heat, reliable heat rejection is essential for keeping equipment and production systems operating properly. The WST Series FRP Square Cooling Tower is designed for industrial and HVAC applications where efficient water cooling, durable construction and dependable operation are required.
The WST Series uses an induced draft cooling system to move air through the tower while warm circulating water passes through the fill media. Heat is transferred from the water to the air, with a portion of the water evaporating during the process. The cooled water is collected in the basin and returned to the system.
Wet Point Cooling Towers manufactures WST Series cooling towers for applications where cooling capacity, operating conditions, available space and long term service requirements need to be considered together.
What Is the WST Series Cooling Tower?
The WST Series is a square type FRP cooling tower designed around an induced draft configuration. Its construction combines FRP components with a water distribution system, fill media, drift eliminators, axial fans and other components required for evaporative cooling.
Unlike a cooling tower that simply circulates water, an evaporative cooling tower removes heat through contact between circulating water and moving air. This makes the interaction between the fill, water distribution system and airflow important to overall tower performance.
The WST Series can be considered for applications such as process cooling and HVAC systems where warm water needs to be cooled before being recirculated.

In Simple Terms:
WST Series Cooling Towers are square-shaped, high-efficiency cooling systems designed to deliver reliable and uniform performance across a wide range of industrial and HVAC applications. Constructed with durable fiber-reinforced plastic (FRP), these towers offer excellent resistance to corrosion, weather conditions, and long operational life.
The WST series features a fixed header water distribution system equipped with non-clogging spray nozzles, ensuring even water flow over the PVC fill media for maximum heat transfer efficiency. Its modular fill design, efficient drift eliminators, and energy-saving induced draft axial fans contribute to low operating costs and minimal water loss.
How Does a WST Series Cooling Tower Work?
The WST Series works through the principle of evaporative cooling. Warm process water enters the tower and is distributed over the fill media. At the same time, the fan draws air through the tower.
As the water comes into contact with the moving air, a small portion of the water evaporates. This evaporation removes heat from the remaining water, lowering its temperature.
The cooled water then collects in the cold water basin and can be pumped back into the industrial or HVAC process.
WST Series Cooling Process

This simple cycle allows the cooling tower to continuously reject heat from a circulating water system.
WST Series Cooling Tower Specifications
Cooling tower selection should be based on operating requirements rather than capacity alone.
Before selecting a WST Series model, the project team should establish:
Parameter | Why It Matters |
Heat load | Determines the amount of heat the tower must reject |
Water flow rate | Determines the required circulation capacity |
Hot water temperature | Establishes the entering water condition |
Cold water temperature | Defines the required cooling result |
Wet bulb temperature | Influences achievable cooling performance |
Range | Difference between entering and leaving water temperature |
Approach | Difference between cold water temperature and ambient wet bulb temperature |
Fan arrangement | Determines how air is moved through the tower |
Available space | Influences tower dimensions and installation |
Water quality | Affects scaling, corrosion and biological control |
For an accurate selection, provide your operating data to the cooling tower manufacturer rather than choosing a model based only on nominal capacity.
How to Select the Right WST Series Cooling Tower
A cooling tower should be sized according to the actual process.
1. Determine the Heat Load
Identify how much heat the cooling system needs to reject. This is the starting point for tower selection.
2. Confirm Water Flow
The required circulating water flow helps determine the appropriate tower configuration and capacity.
3. Check Operating Temperatures
Provide the expected hot water temperature, required cold water temperature and site wet bulb temperature.
4. Consider Water Quality
Poor water quality can contribute to scaling, corrosion and biological growth. The cooling tower and water treatment strategy should therefore be considered together.
5. Evaluate Available Space
Check the footprint, tower height, maintenance access, airflow requirements and surrounding structures before finalizing the installation.
6. Consider Maintenance
Fans, motors, fill media, nozzles, drift eliminators and water basins need inspection and maintenance. Easy access to serviceable components can reduce maintenance difficulties.
WST Series Cooling Tower Maintenance
Even a well designed cooling tower requires regular maintenance. Performance can decline when fill media becomes fouled, water distribution is uneven or mechanical components are not maintained properly.
A practical maintenance program should include:
- Inspecting fan blades and mechanical assemblies
- Checking motor condition
- Cleaning or inspecting fill media
- Checking spray nozzles for blockage
- Inspecting drift eliminators
- Cleaning the cold water basin
- Monitoring circulating water quality
- Checking for scaling and corrosion
- Inspecting water distribution
- Checking vibration and unusual operating noise
The maintenance frequency should depend on operating hours, water quality, environmental conditions and the application.
