Counter Flow Cooling Towers
Counter Flow Cooling Tower
“Natural Draft cooling Towers” Natural contacts ambient air rising up through the tower either by forced draft using large fans in the tower. Natural draft is utilizes a tall chimney. Warm, moist air naturally rises due to the density differential compared to the dry, cooler outside air. Warm moist air is less dense than drier air at the same pressure. This moist air buoyancy produces an upwards, current of air through the tower.Natural that appears like a natural draft setup, though airflow is assisted by a fan.This association is misleading, as the same kind of cooling towers are often used at large coal-fired power plants as well. Conversely, not all nuclear power plants have cooling towers, and some instead cool their heat exchangers with lake, river or ocean water. The heat required to evaporate the water is derived from the water itself, which cools the water back to the original basin water temperature and the water is then ready to recirculate. Natural cooling towers have become the design standard for all natural-draft cooling towers because of their structural strength and minimum usage of material. The hyperboloid shape also aids in accelerating the upward convective air flow, improving cooling efficiency. These designs are popularly associated with nuclear power plants. That contact causes a small amount of the water to be lost as windage (W) and some of the water to evaporate.
Closed looped cooling tower is one of the methods of heat transfers. They are hybrids that pass the working fluid through a tube bundle, upon which clean water is sprayed and a fan-induced draft applied. The resulting heat transfer performance is much closer to that of a wet cooling tower, with the advantage provided by a dry cooler of protecting the working fluid from environmental exposure and contamination.
In Evaporative Cooling Tower a small portion of water is cooled and evaporate into a moving air stream which provides cooling to the rest of that water stream. This evaporating water absorbs heat energy from the remaining water and reduces its temperature.
Quantitatively, the material balance around a hybrid cooling tower is governed by the operational variables of make-up volumetric flow rate, evaporation and windage losses, draw-off rate, and the concentration cycles.
The water pumped from the tower basin is the cooling water routed through the process coolers and condensers in an industrial facility. The cool water absorbs heat from the hot process streams which need to be cooled or condensed, and the absorbed heat warms the circulating water. The warm water returns to the top of the cooling tower and trickles downward over the fill material inside the tower. As it trickles down, it contacts ambient air rising up through the tower either by natural draft or by forced draft using large fans in the tower. That contact causes a small amount of the water to be lost as windage/drift and some of the water to evaporate. The heat required to evaporate the water is derived from the water itself, which cools the water back to the original basin water temperature and the water is then ready to recirculate. The evaporated water leaves its dissolved salts behind in the bulk of the water which has not been evaporated, thus raising the salt concentration in the circulating cooling water. To prevent the salt concentration of the water from becoming too high, a portion of the water is drawn off/blown down for disposal. Fresh water make-up is supplied to the tower basin to compensate for the loss of evaporated water, the windage loss water and the draw-off water.
RCC Cooling Tower
RCC Cooling Tower
RCC Construction also both in Cross Flow and Counter Flow design. The structure of Cooling Tower is complete with RCC, the tower life will be more than timber as well as FRP and higher capacities are available in multi cell construction.

Fanless Cooling Tower
Fan Less Cooling Towers
Fanless Cooling Towers is a design in which the flow is directed perpendicular to the water. The air continues through the fill and thus past the water flow into an open plenum volume. A fan forces the air out into the atmosphere. Air flow enters one or more vertical faces of the cooling tower. Water flows through the fill by gravity.

Dry Cooling Tower
Dry Cooling Towers are nothing but type radiator Cooling. All the heat Transfer areas can be easily approach, the periodical cleaning and maintenance will be very easy and also the replacement period is also more when comparing with other cooling Tower system. Oil/water is cooled by a single heat Exchanger system, cost energy cooling water and maintenance spent can be reduced, various hot media can be cooled simultaneously by the same fan using parts. The tubes are wounded with integral Aluminium or copper wire type fins for increasing the Heat Transfer areas. In this system the core area Heat Transfer area is cooled with a intake cooling Fan at the top with the help, TEFC Electric motor in counter flow method to maximize heat transfer efficiency. The hot media primary will be circulated inside the tubes and the atmospheric air is used as the secondary media to cool the primary media.
