General Features

Design:

Evaporative (FRP) Cooling towers are of vertical induced draft counter flow design with uniform water distribution and optimal heat transfer. Towers can be installed independent of wind direction. The tower casing is made from tough fiberglass and has sufficient strength to withstand high velocities and vibrations. The water collection sump is leak proof and avoids water spillage.

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. The fill is of rigid Poly Vinyl Chloride (PVC) and is of honeycomb design with very large contact surface area.

Casing:

The tower casing is made of tough fiberglass reinforced plastic (FRP) and has sufficient structural strength to withstand high wind velocities and vibrations. UV - stabilized 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.

Fill:

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.

Sprinkler:

Automatic rotary sprinkler system made of Nylon 66 material, with rotary head and sprinkler pipe distributes the hot water over the entire space of the filler. Sprinkler pipes are non-clogging, require low pressure to operate and assures uniform water flow with minimal operating pump head. The FRP eliminators attached to sprinkler pipe are specifically designed for low pressure drop and minimises the drift loss of water.

Drift Eliminator:

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.

Axial Fan:

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.

Motors:

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.

Corrosion Free:

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.

Lightweight:

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.
