COOLING TOWERS

frp-cooling-tower

Canara manufactures & exports concrete (RCC) counterflow cooling towers using vide varieties of film and splash fills selected based upon the circulating water quality, either for fresh water or sea water application.

Generally, reinforced cement concrete cooling towers are constructed as per the requirement of the customers. These towers are either offered on a turnkey basis by Canara or Civil construction can be in the customer's scope. However, detailed Engineering for RCC construction is offered by Canara. Designing and construction is done in accordance with Indian Standards (IS) or American Concrete Institute (ACI) standards.

Normally, for Sea water application special RCC structure of the Corrosion prevention system (impressed current corrosion prevention system) is required. This system protects the reinforcing steel and concrete from degradation due to corrosion and designed for a life of 50 years. The concrete surface is coated with special protection paints like Polyurethane to protect from sea water.

SOME OF THE SALIENT FEATURES OF CANARA RCC COUNTERFLOW COOLING TOWERS

1.
High quality cooling towers designed as per IS/ACI standards.
2.
A wide variety of splash and film fills are used/selected based upon the circulating water quality.
3.
RCC cooling towers have excellent durability & have a very long service life and can withstand high wind and seismic loads.
4.
The RCC structure is not affected by U.V. radiation, high temp. and circulating water quality, hence longer life.
5.
As the maintenance of RCC is almost negligible, the high initial construction cost, turns out to be cost effective and economical on a long run.
6.
RCC being a composite material of steel and concrete, is capable of resisting compressive, shear and bending forces.
