FRP Cooling Tower
Introduction
Cooling tower systems are normally associated with air-conditioning systems, refrigeration systems, and industrial processes. The water is sprayed or dripped into a large chamber. Air is forced through this chamber by a thermostatically controlled fan. The primary task of a cooling tower is to reject heat into the atmosphere. This heat rejection is accomplished through the natural process of evaporation that takes place when air and water are brought into direct contact in the cooling tower. The evaporation is most efficient when the maximum water surface area is exposed to the maximum flow of air, for the longest possible period of time. Cooling towers are designed in two different configurations, counterflow and crossflow. The specific configuration indicates the direction of airflow through the tower relative to the direction of the water flow. Cooling tower water and air distribution systems are designed in concert, with each playing an equally important role in determining the efficiency and proper application of the cooling tower.
FRP cooling towers are mainly divided into circular counterflow FRP cooling tower, square counterflow FRP cooling tower and square crossflow FRP cooling tower.

Features
Design:
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 the 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 a 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 the gel coat for a 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 a 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.
Sprinkler:
An 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 the minimal operating pump head. The FRP eliminators attached to the sprinkler pipe are specifically designed for low-pressure drop and minimizes the drift loss of water.
Drift Eliminator:
Reduces carryover losses of water. The eliminator is of rigid PVC. 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 eac
h removing water droplets on the entire surface of the cell.
Fan:
Yukuo has professional FRP fans.The high-efficiency design ensures low running cost and the lowest possible noise level.
Motors:
The motors are totally enclosed , 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, are hot-dip or spray galvanized.
Lightweight:
The towers are compact and lightweight resulting in easy delivery to site and installation. Lightweight 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. Towers of higher capacity can easily be assembled at the site and then installed in a manner similar to small towers. Maintenance is considerably reduced because the fan, sprinkler fill, and eliminator can easily be approached from the top without disturbing the cooling tower casing.
Applications
It has been used in various sectors. It is particularly suitable for cooling water circulation systems such as air conditioning, refrigeration, air compressor stations, heating furnaces, and condensation processes.
