The tower casing is made from tongue fiberglass reinforced plastic (FRP) and has sufficient structural strength it can withstand high wind velocity and vibrations. UV – stabilized resin is used along with gelcoat for resist of sun rays. It requires no painting & is compact in design with long life. 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 6 mm, 12 mm, and 19 mm with sheet thickness of 1 mm and 1.2 mm. PVC modules are vacuum formed and have been provide with double edges to give highly efficient and robust packing. It is the heart of cooling tower.
Specially designed energy efficient fans are of induced draft axial type with adjustable pitch. Material chosen are non corrosive of plastic, FRP or aluminum alloy, the high efficiency design ensures low running cost and the lowest possible noise level. Fan blade pitch is factory set and dynamically balanced. Aerodynamically designed adjustable blade type axial efficient ensures large air flow at low static pressure & dynamically balanced reduce vibration & more efficient to remove heat from water in cooling tower.
Squirrel cage TEFC induction motor with IP 55 weather proof electric motor suitable for humid outdoor weather condition.
The round Bottle Tower Have Rotary aluminum alloy sprinkler/ plastic sprinkler with seated Ball bearings is designed to take care of radial and thrust loads rotating at 5 to 7 R.P.M. Distributes water through PVC Branch pipes. it sprays water on the PVC fills uniformly. The frp eliminators attached sprinkler pipe are specifically designed for low pressure drop and minimize the drift loss of water. The square bottle cooling tower have SCSP nozzles distribute water evenly through a wide spray angle without any dry pockets over the fill area. Nozzle are light weight and reduce the frequency of clogging.
Reduces carry over loss of water. The eliminators is of rigid PVC. (applicable for square type cooling tower.) FRP drift eliminators reduces moisture losses through fan draught. (applicable for round cooling tower.)
The structural of the tower support the casing, basin and motor mounting the loads to the foundation. These are of mild steel and are hot dip galvanized so as to resist corrosion.
Tower of lower capacity are completely factory assembled before dispatch. At site the tower has just to be bolted, on the RCC/brick masonry foundation, thus saving a lot of installation time. Tower of higher capacity can easily be assembled at site and then installed in a manner similar to fan, sprinkler fill and eliminator can easily be approached from the top without disturbing the cooling tower casing.
