Bottle-Type FRP Cooling Towers in Pakistan
AKD Cooling Towers supplies, installs, repairs and maintains bottle-type FRP cooling towers for industrial and commercial applications. Our team reviews cooling requirements, operating conditions and site constraints before recommending a suitable tower, replacement part or service solution.
What Is a Bottle-Type Cooling Tower?
A bottle-type cooling tower is a round FRP cooling tower named for its circular, bottle-like external structure. “Bottle type” describes its physical shape and construction; it does not independently define the tower’s cooling capacity or complete operating arrangement. FRP is commonly used for the casing because it provides corrosion resistance and relatively lightweight construction. Its compact circular design can be useful where installation space is limited. Many bottle-type models operate as counterflow, induced-draft cooling towers with a top-mounted axial fan. These towers are commonly used for industrial processes, chillers and commercial HVAC systems.
How Does a Bottle-Type Cooling Tower Work?
A bottle-type cooling tower cools circulating water by distributing hot water over fill media while a fan moves ambient air through the tower.
- Hot circulating water enters the tower.
- A sprinkler or water-distribution system spreads the water.
- Water flows downward over PVC fill media.
- Ambient air enters through the lower air-inlet area.
- A top-mounted fan draws air upward.
- Air and water move in opposite directions.
- A small portion of the water evaporates.
- Evaporation removes heat from the remaining water.
- Cooled water collects in the bottom basin.
- The water returns to the industrial process or HVAC system.
Counterflow means water moves downward while air moves upward.
Induced draft means a discharge-side fan pulls air through the tower.
Evaporative cooling removes heat by evaporating a small portion of the circulating water.
Main Components of a Bottle-Type Cooling Tower
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 Eliminators
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
Is a bottle-type cooling tower suitable for industrial use?
Yes. A correctly selected bottle-type cooling tower can serve industrial chillers, compressors, manufacturing equipment, process cooling and commercial HVAC systems. Suitability depends on the required heat load, water-flow rate, inlet and outlet temperatures, water quality and available installation space.
What information is required to select the correct cooling-tower capacity?
Cooling-tower selection normally requires the circulating water-flow rate, hot-water inlet temperature, required cold-water outlet temperature and local wet-bulb temperature. Operating hours, process heat load, water quality, site conditions, available space and noise requirements should also be reviewed.
How much does a bottle-type cooling tower cost in Pakistan?
The price depends on cooling capacity, tower dimensions, FRP specification, fill media, fan, motor, water-distribution system, delivery location and installation requirements. An accurate price requires a project-specific quotation based on the customer’s operating and site conditions.
How often should a bottle-type cooling tower be maintained?
Maintenance frequency depends on operating hours, water quality, environmental dust and equipment condition. The basin, fill media, water-distribution system, fan, motor and drift eliminator should be checked regularly to prevent scale, blockage, vibration and reduced cooling performance.
Can an old bottle-type cooling tower be repaired?
Yes. Many bottle-type cooling towers can be repaired or refurbished. Common work includes FRP crack repair, basin leak repair, fill replacement, sprinkler or nozzle replacement, fan balancing, motor servicing and drift-eliminator replacement. An inspection should determine whether repair or complete replacement is more practical.
