Energy-Efficient Closed Circuit Cooling Tower Solutions in India

closed loop cooling tower

Closed Circuit Cooling Towers are designed to deliver efficient heat rejection while ensuring the process fluid remains clean and free from contamination. Unlike open towers, the circulating fluid passes through a sealed coil system, eliminating direct contact with outside air. This design significantly reduces scaling, minimizes water treatment costs, and enhances equipment life.

Often referred to as a closed loop cooling tower, this system is widely chosen by industries that demand hygiene, reliability, and low maintenance. By keeping the cooling medium isolated, it not only preserves fluid quality but also ensures consistent performance even in challenging environments. This makes Closed Circuit Cooling Towers a preferred solution for HVAC systems, data centers, chemical plants, and food & beverage industries where efficiency and cleanliness are critical

Key Components of Closed Circuit Cooling Towers

Heat Exchanger Coils

The core of the system where hot process fluid passes through coils and is cooled by circulating water and air, ensuring zero contamination.

cooling tower water distribution

Water Distribution System

Sprays water evenly over the coils to enhance heat transfer efficiency.

Cooling Tower fills

Fill Media

Improves cooling by increasing surface area for water-air contact, maximizing thermal performance.

Industrial cooling tower fan

Fans

Draw or force air through the system to support effective cooling performance.

Cooling Tower Drift eliminator

Drift Eliminators

Prevent water droplets from escaping the tower, reducing water loss and maintaining efficiency.

Cooling Tower Component – Water Basin

Basin & Pump System

Collects cooled water and circulates it back over the coils for continuous operation.

cooling towers casing

Casing & Frame (FRP/Steel)

Provides structural support and protects internal components from weather and corrosion.

FAQ

A closed circuit cooling tower circulates process fluid through a sealed coil, while water flows over the coil to remove heat. Unlike open towers, the process fluid never comes in direct contact with air or water, reducing co

Rakshan uses corrosion-resistant coils, high-efficiency water distribution systems, and energy-saving fans. This ensures stable performance, longer coil life, and consistent cooling efficiency.

Yes. Because the process fluid is protected, there's less need for chemical dosing, cleaning, or fluid replacement. Over time, this reduces both downtime and operating expenses.

No heavy treatment is needed for the process fluid, since it's sealed inside coils. Only the spray water loop requires periodic treatment to prevent scaling and microbial growth.
