Fanless Cooling Towers does not contain any fan or fill used to cool the water and so it is called fanless and fill less cooling tower. The louvers are used as the sidewall of the cooling tower to restrict the water spillage.
In Fanless Cooling Towers, the water is cooled with natural atmospheric air traveling 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 an atmospheric cooling tower or Fanless and fill less 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 principle of transfer of heat from hot water to atmospheric air by arranging 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 a minimum of 0.5 kg./ sq. cm pressure. Water enters nozzle tangentially at the top and is given spiral action in the spiral chamber. This spiral action increases as water approach the discharge orifice and come out centrally from discharge orifice with fine droplets in an umbrella shape. The 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.
Louvers are Horizontal and circular in shape are made of molded FRP (Fiber-reinforced plastic) using isophthalic resin with neopentyl glycol and suitable U.V. Stabilisers. The louvers have inbuilt mist-eliminators to minimize mist losses.
Made up of thermoplastic pipes reinforced with FRP fitted with thermoplastic(GF Nylon/PP)whirl jet nozzles. The nozzles are self-cleaning, hence no regular Maintenance needed. The nozzles feature a center post design, it provides long service life and excellent spray pattern uniformity by Precisely controlling the fluid of vertex in the nozzles whirl chamber. Carefully Engineered spray system to assure maximum cooling capacity/cubic foot of Tower volume. The entire utilization of tower area is achieved by Specially designed spray nozzles in a pattern determined by test and experience to assure the most effective cooling performance.
The performance of the cooling tower greatly depends upon the water distribution over the fills. Nozzles distribute water evenly through a wide spray angle without any dry pockets. They are lightweight and reduce the frequency of clogging. The nozzles produce a solid cone spray of water that is distributed in a square pattern onto the fills.
Vertical supports are made of molded FRP with foundation plates also of FRP having stiffened core for better strength and stability.
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. They are lightweight and reduce the frequency of clogging. The Solid Cone Square Pattern (SCSP) nozzles produce a solid cone spray of water that is Distributed in a square pattern onto the fills.
The nut bolts and washer are made of reinforced thermoplastic with main structural bolts of MS-GF Nylon. Therefore all the hardware is of high strength and corrosion-free.
