Evaporative Cooling Towers are installed mainly in the cement & sponge iron industry.

The essential components of an evaporative cooling tower are :

The gas inlet cone with accessories for gas distribution devices.
The cylindrical cooling tower casing in which the exhaust gases are cooled and conditioned by
        evaporation of water.
An integrated mixing zone in the cooler which in special cases is added to the evaporative
        section.
The dust collection hopper.
Water spray system with high pressure spill back nozzles: lances fixed to the tower casing,
        water supply with multi-stage pumps and motor control valve in the return line, temperature
        control system with sensor, controller and indicating instruments
                                                                    OR ALTERNATIVELY
Spray system with air atomizing low pressure spray system: lances fixed to the tower casing,
        water supply, compressed air supply, temperature control system with sensor, controller and
        indicating instruments.
