Mihir Polacel CM cooling tower operates according to the counterflow principle. The water to be cooled is fed into the tower at the top and is distributed by full cone nozzles with a low pressure drop, and flows down, in the form of a thin water film and small droplets, over the largest possible fill surface for the heat transfer.
The water falls through the fill and is collected in a FRP/RCC basin at the bottom of the tower. The atmospheric air is sucked in through the opening for air inlet on all sides at the lower portion of the tower and moves up through the PVC fill. The air moving up cools the falling water. Here the transfer of heat takes place by evaporation and direct contact. The air inlet is covered by HDG steel mesh or plastic louvers if air inlet height is less then one meter. In case of air inlet height above one meter, air entry is kept open for free flow of air.
The selection of materials for the Mihir Polacel CM cooling towers is based on the requirement that they must be completely resistant to corrosion and chemicals. This has been achieved through the exclusive use of PVC, polypropylene, fiberglass reinforced polyester (FRP) and hot dipped galvanized steel for supports.
