Unlike conventional open cooling towers, a closed loopsystem keeps the process fluid inside a sealed coil circuit. The cooling waterand air pass over the outside of the coil, removing heat without direct contactwith the process fluid. This helps protect pumps, heat exchangers, compressors,furnaces, generators, chillers and other valuable equipment from scaling,contamination and corrosion.
At FCI, our closed loop cooling towers are engineered forlong-term industrial performance, especially in harsh operating environmentswhere corrosion resistance, water conservation and uninterrupted operationmatter the most.
Why Choose Closed Loop Cooling Towers?
Closed loop cooling towers are ideal where the coolingcircuit must remain clean and controlled. They help reduce:
Scaling inside process equipment
Fouling of heat exchangers and jackets
Corrosion in pipelines and machinery
Water contamination in the process circuit
Frequent shutdowns for cleaning and maintenance
Chemical consumption in the closed circuit
The result is a more reliable cooling system with betterequipment life and lower operating costs.
Designed for Industrial Duty
FCI closed loop cooling towers are built for demanding industriessuch as:
Fertilizer plants
Oil & gas facilities
Power generation
Chemical and petrochemical plants
Pharmaceutical and food processing
Steel, textile and heavy manufacturing
FRP Construction for Long Service Life
Built using fiberglass reinforced plastic (FRP), our closed loop cooling towers resist corrosion, chemicals and harsh weather far better than steel or galvanized systems. This means longer service life, lower maintenance and dependable performance in tough industrial conditions.

Frequently Asked Questions
Everything you need to know about FCI Composites closed loop cooling towers.
A closed loop (closed circuit) cooling tower keeps the process fluid inside a sealed coil while cooling water and air pass over the outside of the coil, removing heat without direct contact and protecting equipment from scaling, contamination and corrosion.
In an open cooling tower the process water is exposed to air and contaminants. A closed loop tower isolates the process fluid in a sealed circuit, keeping it clean and protecting pumps, heat exchangers and machinery.
FRP construction resists corrosion, chemicals and harsh weather far better than steel or galvanized systems, giving a longer service life, lower maintenance and dependable performance.
They are used in fertilizer, oil & gas, power generation, chemical and petrochemical, pharmaceutical, food, steel, textile and heavy manufacturing plants.
