It is the top most part of the cooling tower which is responsible to dissipate heat form the system. It has to be designed such a way that it provides a smooth path for the flow of air.
Fan is a prime mover and is responsible to generate negative pressure inside the fan stack to get maximum air inlet. Generally, cooling towers are equipped with axial flow propeller type fans, either directly driven by motor or by gearbox. They play a key role in the efficiency of a cooling tower if designed aerodynamically.
Drift eliminators or mist eliminators are responsible for eliminating the extra drift generated due to the negative pressure, by fan, thereby decreasing the water losses.
It is responsible for evenly distribution of water inside the cooling tower area. A proper distribution system plays a key role when humidity level during rainy seasons is high.
These provide the water sprays to wet the fill. Uniform water distribution at the top of the fill is essential to achieve proper wetting of the entire fill surface.
Generally, cross-flow towers have inlet louvers. The purpose of louvers is to equalize air flow into the fill and retain the water within the tower.
Fills are employed as turbulence media to facilitate heat transfer by maximizing air and water contact.
Basin collects the outlet/cooled water from the tower to deliver it back into the system.
It the temperature of the hot water coming from the process or system inside the cooling tower.
It is the temperature of the cold water which is collected into the basin after processing.
It is volumetric flow rate of water, in the system, intended to be cooled in the cooling tower.
It is least temperature which can be achieved by any wet cooling tower.
It the temperature difference between the outlet/cold water temperature and wet bulb temperature. The lower the difference the better is the efficiency of a cooling tower for a given capacity.
It is the temperature difference between the inlet water and outlet water of a cooling tower.
It is defined as the ratio of the desired heat loss through the system upon the input power to the cooling tower. The complete design of a cooling tower can give you good efficiency. SFG cooling towers gives the best efficiency in comparison to any competitor due to its researched thermal design which gives it versatility to perform even at humidity levels as high as 90-95%.

Ƞ = (TI – TO)*100/ (TI – Tw)


It is the fluid which flows in the primary circuit of the process which, absorbs heat from the machine.
It is the fluid which flows in the secondary circuit of the system and facilitates the cooling of the primary fluid. Further, it goes to the condenser assembly in secondary circuit.
It is the temperature of the primary fluid which it gains after absorbing heat from the process.
It is the temperature of the primary fluid after being process in the heat exchanger.
It is a temperature at which secondary fluid enters the heat exchanger to absorb heat from the primary fluid.
It is the temperature of the secondary fluid which it gains after absorbing heat from the primary fluid.
Number of passes are selected in the very beginning of designing of heat exchanger. Increased no. Of passes optimizes the size of heat exchanger with increased surface area.
It the difference between secondary fluid out temperature and primary fluid outlet temperature.


Material of construction of a tank is significant to be considered while designing a tank for the suitable application.
It is the placing of various nozzles over a tank which is to be considered during designing stage keeping the site conditions in mind.
It is an auxiliary attached to the tank which indicates the content volume inside the tank. A level indicator can be float type, tube type or electronic.
It is a type of nozzle placed at the top of a tank to dispose of the gas being generated inside the tank.
Saddle support are provided with horizontally mounted tanks for supporting the tank. A proper saddle can give a better life to a tank and better physical stability.


Ventury is a part of scrubber which works on the Bernoulli’s principle to get the higher velocity of gas.
Gas inlet point is provided at the bottom of scrubber column to take the harmful gas inside the scrubber from the process.
It is provided at the top of scrubber column to release the neutralized gas into the atmosphere through chimney.
Blower is provided to generate high negative pressure for effective suction of all the harmful gases from the source.
Spray assembly facilitates the spraying of neutralizing liquid, which is generally water or base in some cases.
It is the main body which encases all the components like spray assemblies, Paul-rings, packing bed inside it. It is where the harmful gas is agitated with the neutralizing liquid.
It is the media provided inside the scrubber column to create the turbulence in the path of gas, hence providing maximum time for the neutralization.
It is a tank provided at the bottom of the scrubber column which contains the neutralizing liquid inside it. It is connected to a recirculation pump which recirculates the liquid inside the scrubber column.
It is the pathway of harmful gases starting from the source to the inlet of scrubber column.
It is the main component responsible to arrest the harmful gases from the source. Its size and physical shape depends upon the system where it is installed.
