CONVERSION OF OLD TIMBER COOLING TOWERS TO 

NEW PULTRUDED FRP COOLING TOWERS

Conversion of old Timber cooling tower to new Pulturded FRP cooling tower

Along with manufacturing a wide variety of new cooling towers due to our flexible, project oriented Engineering and designs, Canara has diversified, expertise in conversion of old timber cooling towers to pulturded FRP cooling towers.

Many cooling tower users prefer to repair existing old timber cooling towers, which either have out lived their life or damaged prematurely due to bad quality of materials or other reasons. In reality if the overall condition of the existing cooling tower is bad and requires a major structural repairs, then it is technically and economically advised to convert the old timber cooling tower to pulturded FRP cooling tower.

During repairing of old timber cooling towers, only part of the bad quality items are replaced, so un replaced items need to be replaced after some time. Practically repairing of old timber cooling towers takes place every 1- 2 years, which proves very costly affair. Moreover partially repaired old timber cooling tower may fail, collapse partially or fully, which will be dangers in all aspects.

Suppose if the old timber cooling tower is of crossflow design and circulating water is a good quality then a techno commercial proposal can be offered to convert the crossflow cooling tower to pulturded FRP counterflow cooling tower using high efficient PVC film fills, stating benefits of lower fan power consumption , pumping head etc. Similarly if the existing old timber cooling tower is counterflow with film fills and circulating water is of poor quality, then a new pulturded FRP crossflow cooling tower with splash fill may be offered considering the economics of fan power, pumping head etc.

Most of the times the RCC basin of old timber cooling tower is in good condition. Canara built pultruded FRP cooling tower be it crossflow or counterflow in the same basin, absolutely without any basin modifications. If the mechanical equipment like fan , motor , fan gear box , fan cylinder, drive shaft etc. are in good condition Canara proposes to reuse them either fully or partially in the new pulturded FRP cooling tower.

Pultruded FRP cooling tower has a long life almost maintenance free operation , unlike timber cooling towers in which water needs to be circulated always, (even if the plant is shut) to maintain the timber components wet, as wet and dry operation reduces the life of the timber considerably. This consumes of a lot water and pumping power. Pulturded FRP does not affect in wet and dry operation of cooling tower.

Pulturded FRP cooling towers have many benefits compared to timber cooling towers. The structure , fan deck, handrail, stair case , ladder etc are of pulturded FRP. Fan cylinder, casing , louvers are of FRP . Hence expected life is more than 25 years, which is 2 - 3 times more than timber. All bolt nuts washers , brackets etc. used in the pulturded FRP cooling tower are of Stainless Steel Grade 304-316.

SOME OF THE ADVANTAGES OF PULTRUDED FRP COMPARE TO TIMBER IN COOLING TOWERS ARE

1.
Exceptional Chemical & corrosion resistant to acids, alkalis, sea /brackish water.
2.
High impact strength and rigidity allows deformation without fracture.
3.
Inert to biological and micro organisms attack. Tendency to algae growth is negligible.
4.
High temperature resistance makes it ideal for high temperature process cooling.
5.
Resistant to toughest weather conditions, be it ultra violet rays, sunlight, sand storm, snow falling, acid rains.
6.
Very low deposition of scale, algae as the surface is smooth.
7.
High fire resistance (flame spread rate <25), hence no need for costly fire protection system.
8.
Life expectancy is more than 25 years. (more than 2 – 3 times of timber)
9.
Tensile and compression strength equivalent to steel.
10.
Light weight, hence easy transportation, handling and erection.
11.
Excellent creep and fatigue performance due to high glass content.
12.
The cooling towers can be installed on pier less RCC basin = Low cost & Faster construction.
13.
Does not affect due to wet and dry operation.
