Square FRP Cooling Towers in Pakistan
AKD Cooling Towers manufactures, supplies, installs, repairs and maintains square FRP cooling towers for industrial processes, water-cooled chillers and commercial HVAC systems. Each square cooling tower in Pakistan is selected according to the required water flow, thermal load, site conditions and available installation space.
What Is a Square Cooling Tower?
A square cooling tower is a mechanical-draft evaporative cooling tower built with a square or rectangular external structure. FRP construction is commonly used because it is lightweight, corrosion-resistant and suitable for industrial cooling environments. Square cooling towers can be designed in counterflow or crossflow configurations depending on the required cooling duty, airflow arrangement and site conditions. Their straight-sided design also makes them suitable for single-cell or modular multi-cell installations where higher cooling capacity or future expansion may be required. They are commonly used for industrial process cooling, water-cooled chillers and commercial HVAC systems.
How Does a Square Cooling Tower Work?
A square cooling tower removes heat from circulating water by bringing the warm water into direct contact with moving air. A small portion of the water evaporates during this process, carrying heat away and reducing the temperature of the remaining water.
- Hot water from the process, chiller or HVAC system enters the cooling tower.
- The water-distribution system spreads the hot water evenly across the fill media.
- Water flows downward through the fill, increasing the contact area between water and air.
- A mechanical fan draws ambient air through the tower.
- In a counterflow design, air moves upward against the downward flow of water. In a crossflow design, air moves horizontally across the falling water.
- A small portion of the circulating water evaporates and removes heat from the remaining water.
- Drift eliminators help reduce water droplets carried out with the exhaust air.
- The cooled water collects in the cold-water basin at the bottom of the tower.
- The water is then pumped back to the process or cooling system and the cycle continues.
Counterflow means air moves upward while water moves downward in the opposite direction.
Crossflow means air moves horizontally across the downward-flowing water.
Evaporative cooling means a small portion of the circulating water evaporates and carries heat away from the remaining water.
Modular Cooling for Industrial and HVAC Systems
A square cooling tower is a mechanical-draft evaporative cooling tower with a square or near-square external structure. It removes heat from circulating water by bringing the water into contact with moving ambient air. Square towers may use counterflow or crossflow operation and can be supplied as packaged, single-cell or modular multi-cell systems. Final performance depends on water-flow rate, inlet and outlet temperatures, wet-bulb temperature and project conditions.
Axial Fan and Fan Blades
The axial fan moves air through the tower. Blade balance, pitch, clearance and condition affect airflow, vibration, noise and cooling performance.
Electric Motor
The electric motor powers the fan. Its rating must match the fan design and operating requirements.
Cold-Water Basin
The basin collects cooled water before it returns to the process or chiller circuit. It should remain free from excessive scale, sediment and biological buildup.
FRP Body and Casing
The FRP casing forms the external body and protects the internal components. Material quality, installation and maintenance affect its service life.
Water-Distribution System
A rotary sprinkler or spray-nozzle arrangement distributes hot water over the fill media. Even water distribution supports effective cooling.
PVC Fill Media
PVC fill media increases the contact area and contact time between water and air. Fill selection should consider water temperature, water quality and contamination risk.
Drift Eliminator
A drift eliminator reduces water droplets carried out with the discharge air.
Air-Inlet Section
The lower air-inlet section allows ambient air to enter the tower. Blockages or poor site clearance can restrict airflow.
Float Valve and Make-Up Water System
The float valve controls make-up water and maintains the required basin level.
Support Frame and Connections
The support structure carries the tower load. Inlet, outlet, drain, overflow and make-up connections connect the tower to the circulating-water system.

Frequently Asked Questions
When is a square cooling tower a suitable choice?
A square cooling tower can be suitable for industrial process cooling, water-cooled chillers and commercial HVAC systems where the project requires flexible capacity, efficient use of installation space or a single-cell or multi-cell arrangement. Final suitability depends on cooling load, water flow, operating temperatures, wet-bulb conditions and site requirements.
How is the capacity of a square cooling tower selected?
Capacity is selected using the circulating water-flow rate, hot-water inlet temperature, required cold-water outlet temperature, local wet-bulb temperature and required approach. Site space, water quality, operating hours and the process heat load should also be reviewed before final selection.
Can square cooling towers use multiple cells?
Yes. Square cooling towers can be designed as single-cell or modular multi-cell systems depending on the required cooling capacity, available plant space and future expansion requirements.
What affects the price of a square cooling tower in Pakistan?
Pricing depends on cooling capacity, tower dimensions, FRP construction, fill media, airflow configuration, fan and motor specifications, cell arrangement, delivery location and installation requirements. A project-specific quotation is required for accurate pricing.
Can an existing square cooling tower be repaired or refurbished?
Yes. Depending on its condition, a square cooling tower may be repaired or refurbished instead of completely replaced. Work may include FRP repairs, basin repairs, fill replacement, water-distribution servicing, fan or motor work, drift-eliminator replacement and other component repairs. A technical inspection helps determine the most practical option.
