Cooltech Engineers is an FRP cooling tower manufacturer and exporter in India. Our fibreglass reinforced polyester (FRP) cooling towers resist corrosion, install quickly and are thermally designed for your plant.
An FRP cooling tower is an industrial cooling tower whose structure, casing and fan cylinder are made of fibreglass reinforced polyester (FRP) instead of steel, concrete or timber. Hot process water is sprayed over PVC fill while a fan draws air through it; part of the water evaporates and the rest returns to the plant cooler. Because FRP cannot rust, FRP cooling towers last long in humid, chemical and coastal conditions while staying light enough to install quickly.
Cooltech Engineers manufactures FRP cooling towers in India in 98 models, in single-cell and multi-cell configurations, and exports them to the Middle East, Southeast Asia and Africa.
Every tower is thermally designed for your flow rate, hot and cold water temperatures and site wet-bulb temperature.
Air moves up as water falls through the fill, giving high thermal performance in a compact footprint. Available as single cells or multi-cell banks.
Air flows horizontally across the falling water. Gravity water distribution and open access make inspection and cleaning easy, with low pumping head.
Heavy-duty pultruded FRP beams, columns and panels, assembled on site in counterflow or crossflow design.

Why plants choose FRP over steel, concrete or timber.
FRP does not rust, rot or warp – ideal for moisture, chemicals and coastal air.
Easier to transport and install, with lighter foundations and rooftop-friendly loads.
No repainting or refinishing; the smooth FRP surface is quick to clean.
PVC fill and engineered airflow deliver the cold water temperature you specify.
Long service life and low upkeep reduce total cost of ownership.
Moulded and pultruded FRP suits single cells, multi-cell banks and large field-erected towers.
Cooltech cooling towers serve process, power and HVAC plants, including:
Not sure which material suits your plant? Here is how our three ranges compare.
| Feature | FRP (this page) | RCC cooling tower | Wooden cooling tower |
|---|---|---|---|
| Main structure | Fibreglass reinforced polyester (FRP) | Reinforced cement concrete | Pressure-treated (CCA) timber |
| Models available | 98 | 92 | 107 |
| Configurations | Single-cell & multi-cell; counterflow & crossflow | Single-cell, multi-cell on request; counterflow & crossflow | Induced draft counterflow & crossflow |
| 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 resistance | Excellent – no rust; suits chemical, coastal & seawater duty | Very good – concrete structure with HDG / SS hardware | Good – CCA-treated timber with HDG / SS hardware |
| Typical use | Process & HVAC plants wanting a light, corrosion-proof tower | Large, permanent plants wanting a very long-life structure | Large process cooling where a proven, economical design is preferred |
Cooltech Engineers Pvt. Ltd. designs, manufactures and services cooling towers for industries in India and abroad.
Designing, manufacturing and servicing cooling towers since the 1970s.
Cooling towers supplied and running across India and export markets.
A Cooling Technology Institute (CTI) member and ISO 9001:2015 certified manufacturer; towers are built to CTI standards.
Supplying the Middle East, Southeast Asia and Africa – clients include Dangote Group (Nigeria), Habesha Steel (Ethiopia), SCOUL (Uganda) and Wega Foods (Cameroon).
Cooltech Engineers Pvt. Ltd. is one of India’s established FRP cooling tower manufacturers – making cooling towers since 1975, with 4,900+ installations, CTI membership and ISO 9001:2015 certification. FRP cooling towers are built in 98 models at its own factory in Murbad, near Mumbai, and exported to the Middle East, Southeast Asia and Africa.
A pultruded FRP cooling tower is a field-erected tower built from pultruded fibreglass reinforced polyester beams, columns and panels, with non-slip FRP fan decks and casings. Cooltech supplies them in counterflow and crossflow designs with cell sizes up to 18 × 18 m and flow rates up to 6,000 m³/hr per cell. They are resistant to seawater and hard water.
Counterflow towers move air upward against the falling water and usually need less plan area for the same duty. Crossflow towers move air across the water, use gravity distribution and are easier to inspect and clean. Our engineers recommend the right design after reviewing your flow rate, temperatures and site.
Send the water flow rate (m³/hr), hot water inlet and required cold water outlet temperatures, site wet-bulb temperature, available space and application. With these we can select the model and quote quickly.
Yes. FRP cooling towers are manufactured in India and exported to the Middle East, Southeast Asia and Africa, as well as supplied across India.
Cooltech offers a performance guarantee valid for 12 months from installation or 18 months from supply, whichever occurs earlier.
