Natural Type Cooling Towers are nothing but the water is cooled with natural atmospheric air travelling and the water is sprayed with the help of Spray nozzles and covered with louver covers. This method saves the operating cost because it has no mechanical fans. These cooling towers are called as atmospheric cooling tower or Fanless and fillless cooling tower.
Splash loss and dust prevention capacity: Five-fold water blocker installed at the air vents of the tower top for liquid-water separation. In addition to dust prevention, the water splash loss is between 0.001~0.009% (as per spray pressure). Reduce more than 90% water splash loss than the traditional tower and reduce the transmission of Legionella bacteria
We manufacture Fanless cooling tower assembly is based on the principal of transfer of heat from hot water to atmospheric air by arranging the both air & water to come in contact with each other in such a fashion that heat transfer is maximum. Air and water both travel together in the same direction from top to bottom. Hot water is allowed to spray through specially designed nylon/pp nozzles at minimum 0.5 kg./ sq. cm pressure. Water enters nozzle tangentially at top and is given spiral action in spiral chamber. This spiral action increases as water approaches the discharge orifice and comes out centrally from discharge orifice with fine droplets in umbrella shape. Air around the nozzle is sucked because of air displacement at a lower level near discharge orifice and fresh dry air takes its place.
This assures better contact of air and water and the high cooling efficiency. Note: This cooling tower can be installed where the requirement of the cooling water temperature is not critical. The cooling tower water approach is higher and enough open space is available.
