Welltech Cooling Towers is engaged with manufacturing of FRP square type cooling towers which are offered at suitable prices. Demanding users of Square Cooling Towers are diesel engine, process coolers, machine and air-conditioning plants & D.G Set ect.
The FRP square type Cooling towers we offer have fixed targeted nozzles in the hot water basin. They are designed meticulously for water distribution and are highly resistant to temperature and weathering. The use of targeted nozzles eliminates the need for separate diffusion deck. These FRP square type cooling towers are preferred for minimum drift losses, easy accessibility of internal components, high thermodynamic efficiency and low power requirements. Easy to maintain, these FRP square type cooling towers can be installed on roof tops.
How does the Cooling Tower Works
At the inlet of the FRP square cooling tower, hot water enters and pump up to the header. This header has sprinklers and nozzles, which spray water and increase the surface area of water. Next, water enters PVC filling to reduce its speed. Simultaneously, at the top of the cooling tower, fans are used, which lift air from bottom to top.
Now, due to this slow speed and more water contact area, a good connection is formed between hot water and air. As a result, the water temperature is reduced through evaporation and cooled water is accumulated at the bottom of the tower, which is again used in the boiler.
For better comprehension, let’s explore different types of cooling towers available today:
Selection of Material
All specification for this model are same as that of round bottle shaped cooling towers, although the sprinkler are replaced by nozzles in this model.
These fixed targeted nozzles are used in the hot water basin. They are specifically designed to deliver the required water distribution and are highly resistant against temperature and weathering damage. The use of target nozzles also eliminates the requirement for separate diffusion deck, which is otherwise required to provide complete water distribution throughout the fill area. These nozzles operate under gravity with utmost precision.
Benefits of FRP Cooling Tower
- Compact design, corrosion resistant and lightweight
- Durable service Life
- Higher efficiency
- Minimum drift loss of water
- No contamination due to dust
- Piping cost negligible and suitable for small unit
- Low Maintenance
Evaporative (FRP) Cooling towers are of vertical induced draft counterflow design with uniform water distribution and optimal heat transfer. Towers can be installed independent of wind direction.
The tower casing is made of tough fibreglass reinforced plastic (FRP) and has sufficient structural strength to withstand high wind velocities and vibrations. UV – stabilised resin is used along with gel coat for longer life. It is resistant to local impacts and even if slight damage occurs, local repairs can easily be done. The portion of casing housing fill and eliminator has a round cross section. The water collection sump, also of FRP, is leak proof & avoids water spillage.
The fill is of rigid Poly Vinyl Chloride (PVC) and is of honeycomb design with very large contact surface area. The fill splits the air and water into several streams, increasing the time of contact and also heat transfer between water and air. The fill is in modules and is packed in the tower casing without any cutting for curves. The air pressure drop through the fill is negligible. The fills are available with flute height of 6mm, 12mm, and 19mm with sheet thickness of 1mm and 1.2mm.
The performance of cooling tower greatly depends upon the water distribution over the fills. SCSP nozzles distribute water evenly through a wide spray angle without any dry pockets. They are lightweight and reduce the frequency of clogging. The Solid Cone Square Pattern (SCSP) nozzles produce a solid cone spray of water that is distributed in a square pattern onto the fills.
Reduces carry over losses of water. The eliminator is of rigid PVC (Applicable for square type cooling tower). The individual drift eliminators of S-shaped corrugated sheets are bonded with subsequent layers to create the structure. The entire area is thus divided into several fine S shaped mini zones each removing water droplets on the entire surface of the cell.
Specially designed energy efficient fans are of induced-draft axial type with adjustable pitch. Material chosen are non corrosive of plastic, FRP or aluminium alloy. The high efficiency design ensures low running cost and the lowest possible noise level. Fan blade pitch is factory set and dynamically balanced.
The motors are totally enclosed (IP55), flange type, 415 V, 3 ph, 50 Hz, induction weather proof with SS304 extended shaft and are specially designed for cooling tower application.
The tower casing is of FRP, fill and eliminator are of PVC, and SS304 fasteners are used, thus eliminating corrosion, the biggest enemy of cooling tower. All steel components such as motor support, water distribution pipes, hardware etc., are hot dip or spray galvanized.
The towers are compact and light weight resulting in easy delivery to site and installation. Light weight also saves on structural and masonry. Roof installation can also be done without any special reinforcements.
INSTALLATION, SERVICE & MAINTENANCE:
Towers of lower capacity are completely factory assembled before despatch. At site the tower has just to be bolted, on the RCC / brick masonry foundation, thus saving a lot of installation time. Towers of higher capacity can easily be assembled at site and then installed in a manner similar to small towers. Maintenance is considerably reduced because fan, sprinkler fill and eliminator can easily be approached from the top without disturbing the cooling tower casing.
