Quick answer
What cooling tower is best for a defence facility?
Most defence facilities use an induced draft FRP cooling tower. It is light, quick to install, and does not rust in coastal or humid locations such as naval dockyards and coastal bases.
Large, permanent installations such as ordnance and manufacturing units may prefer an RCC cooling tower. Every tower is thermally designed for its site.
Applications
Where cooling towers are used in defence establishments
Defence sites combine manufacturing, workshops, research and large building complexes, and each has its own cooling load.
Challenges
Cooling tower challenges at defence sites, and how we design for them
Defence sites need equipment that lasts, is easy to support and meets the buyer’s specification. These are the conditions we design around.
Tower types & materials
Which cooling tower suits your facility?
We manufacture all three materials in-house, so we recommend the one that fits your duty, not the one we happen to make.
| Feature | FRP cooling tower | RCC cooling tower | Wooden cooling tower |
|---|---|---|---|
| Best for | Most defence and coastal sites | Large, permanent installations | Economical large-flow cooling |
| Corrosion resistance | Excellent – no rust; suits chemical, coastal and seawater duty | Very good – concrete structure with HDG / SS hardware | Good – CCA-treated timber with HDG / SS hardware |
| Models | 98 | 92 | 107 |
| Capacity | Up to 6,000 m³/hr per cell (pultruded) | Sized to project | 45 – 5,000 m³/hr per cell |
| Civil work | Minimal – FRP or RCC cold water basin | Civil structure built locally from our drawings | RCC cold water basin by purchaser (drawings provided) |
Corrosion-resistant materials throughout, confirmed against your water analysis and site conditions.
| Component | Material of construction |
|---|---|
| Structure and casing | FRP (or RCC / treated timber) |
| Fill | PVC film or splash fill |
| Drift eliminator | PVC, cellular or blade type |
| Nozzles | Polypropylene (PP) |
| Hardware | Stainless steel or hot-dip galvanised MS |
| Fan | Cast aluminium alloy or GRP blades |
| Fan cylinder | FRP |
| Electric motor | To suit your site standards and area classification |

FAQ
Cooling towers for defence: FAQs
Which cooling tower is best for a defence facility?
An induced draft FRP cooling tower suits most defence sites because it is light, quick to install and does not rust. Large, permanent installations may choose an RCC cooling tower.
Do you supply cooling towers for naval and coastal sites?
Yes. FRP cooling towers suit coastal sites because FRP does not rust, and our pultruded FRP towers are resistant to seawater and hard water.
Can you provide technical data for tenders?
Yes. For large cooling towers we provide technical information such as air quantity, L/G ratio, KaV/L, fan curves and performance curves.
Are your cooling towers made in India?
Yes. All our cooling towers are designed and manufactured at our own factory at MIDC Murbad, near Mumbai.
Can you repair or rebuild an existing cooling tower?
Yes. We repair and reconstruct cooling towers of any make, and supply spares such as FRP fans, fills, nozzles, drift eliminators, fan stacks and gearboxes.
What is the life of your cooling towers?
Our FRP, RCC and wooden cooling towers have a life expectancy of 15–20 years with regular maintenance.
