Reasons why FRP cooling towers are clients’ and manufacturers’ favourite

When we see cooling towers in Delhi, we notice that the most commonly used material is the FRP. This material is relatively new as compared to others like wood, steel, concrete etc. Earlier FRP was used as a supporting secondary material implying use in pipes, fan stacks etc. rather than the primary one which is visible to the eyes and therefore people have this misconception that Fibre reinforced polymer is a new material- well it has been around for more than 30 years in cooling towers.

With number of benefits of FRP like sustainability in adverse weather conditions, flexibility in design, cost effectiveness and ease of installation etc. the material has been rapid growth in applications in the industry and has become one of the favourite materials. This has also led to flourishing of number of FRP cooling tower manufacturersin Delhi region. The key is to find a genuine manufacturer who designs compact and space saving cooling towers as these seems to be in demand from the clients. The flexibility of shape with this material is far more than comparable ones like wood, steel etc. it allows the designer to achieve better aesthetics with the same buckling strength. The material has inherent qualities suitable for a weather resistant tower like moisture, corrosion resistance etc. and also requires less maintenance. Areas where there is high wind load, FRP offers better resistance than other alternatives.

Many view FRP as cost effective but one should understand that their initial costs are comparable to others; it is over period of time that this material requires low maintenance, less service, rare replacement, less laborious installation & transportation etc. The industries also experience lower number of downtime due to low maintenance requirements which again is beneficial. Other benefit is it is environment friendly as has no impurities that can percolate into water being cooled. The noise emissions can also be significantly reduced with intelligent designing of structures with FRP.  One can also see increasing use of pultruded FRP towers especially in western countries like US etc. 

Thus we see that growing popularity of FRPcooling towers can be attributed to its various beneficial properties and the liberty it gives cooling tower manufacturers to play around with shape and come up with attractive designs. Some genuine manufacturers are able to produce excellent products with FRP which might have high initial cost but over the time they give better returns as they need low maintenance compared to others.
