Rectangular FRP Cooling Towers in Pakistan
AKD Cooling Towers manufactures, supplies, installs and maintains rectangular FRP cooling towers for industrial plants, process cooling and large HVAC systems. Available in crossflow, counterflow and project-specific configurations, each rectangular cooling tower in Pakistan is selected according to the required water flow, cooling load and site conditions.
What Is a Rectangular Cooling Tower?
A rectangular cooling tower is a mechanical-draft evaporative cooling tower built with a straight-sided, rectangular structure. Its larger and configurable internal area makes it suitable for medium- and high-capacity industrial cooling applications where greater water flow, flexible equipment arrangement or easier maintenance access may be required. Rectangular cooling towers can use either crossflow or counterflow operation and may be designed as single-cell or multi-cell systems. FRP construction is commonly used because it provides corrosion resistance while allowing the tower structure and internal components to be configured according to project requirements.
How Does a Rectangular Cooling Tower Work?
A rectangular cooling tower removes heat from circulating water by bringing warm water into contact with moving ambient air. A small portion of the water evaporates, removing heat from the remaining water before it returns to the industrial process, chiller or HVAC system.
- Hot circulating water enters the cooling tower.
- The water-distribution system spreads the water across the fill media.
- Water flows through the fill, increasing the contact area between water and air.
- A mechanical fan moves ambient air through the tower.
- In a counterflow design, air moves upward against the downward-flowing water.
- In a crossflow design, air moves horizontally across the falling water.
- A small portion of the circulating water evaporates and carries heat away.
- Drift eliminators help reduce water droplets carried out with the exhaust air.
- Cooled water collects in the cold-water basin.
- The cooled water is pumped back to the process or cooling system.
Counterflow means air and water move in opposite vertical directions.
Crossflow means air moves horizontally across the downward-flowing water.
Evaporative cooling means heat is removed when a small portion of the circulating water evaporates.
Built for Higher-Capacity Industrial Cooling
A rectangular cooling tower is a straight-sided mechanical-draft tower that removes heat from circulating water through evaporative cooling. Its modular structure provides a larger fill area, flexible internal configuration and practical maintenance access for medium and high-capacity industrial applications. Rectangular towers may use crossflow or counterflow operation and can be supplied as single-cell, sectional or multi-cell systems. Final performance depends on water-flow rate, inlet and outlet temperatures, wet-bulb temperature and project conditions.
High-Capacity Cooling
The larger fill area and configurable structure make rectangular towers suitable for demanding industrial and commercial cooling loads. The required capacity must be confirmed from verified water-flow and thermal data.
Crossflow or Counterflow
Rectangular towers can use crossflow or counterflow arrangements. In a crossflow tower, air moves horizontally across downward-flowing water. In a counterflow tower, air moves upward while water travels downward.
Practical Maintenance Access
Straight-sided panels and configurable access points can make inspection, cleaning and component replacement easier. Actual maintenance access depends on the tower dimensions and internal layout.
Modular Construction
Rectangular towers can be configured as single-cell or multi-cell systems. A modular arrangement may support larger cooling duties, staged operation and future expansion where the system and site allow it.

Frequently Asked Questions
When should I choose a rectangular cooling tower?
A rectangular cooling tower is suitable when an industrial or commercial system requires higher cooling capacity, flexible internal configuration, easier maintenance access or a single-cell or multi-cell arrangement. Final selection depends on water flow, heat load, available space and operating conditions.
Can a rectangular cooling tower use crossflow or counterflow operation?
Yes. Rectangular towers can use either crossflow or counterflow operation. Crossflow towers move air horizontally across downward-flowing water, while counterflow towers move air upward against downward-flowing water. The correct arrangement depends on capacity, footprint and maintenance requirements.
What information is required to select the correct cooling capacity?
Selection normally requires the circulating water-flow rate, hot-water inlet temperature, required cold-water outlet temperature and local wet-bulb temperature. Process heat load, operating hours, water quality, installation area, noise limits and required number of cells should also be reviewed.
How much does a rectangular cooling tower cost in Pakistan?
The rectangular cooling tower price in Pakistan depends on cooling capacity, tower dimensions, number of cells, FRP specification, fill media, fan, motor, drive system, delivery and installation requirements. A project-specific quotation is required for an accurate price.
Can an existing rectangular cooling tower be repaired or refurbished?
Yes. Many rectangular cooling towers can be repaired or refurbished depending on their structural and mechanical condition. Common work may include FRP repairs, basin leak repair, fill replacement, spray-nozzle or distribution-system servicing, fan and motor repairs, drift-eliminator replacement and other component work. A technical inspection helps determine whether repair, refurbishment or full replacement is the more practical option.
