Cluster head nozzles achieve a very large surface of the sprayed liquid because of several atomizing nozzles. These are used whenever a fine fog-like full cone atomization with relatively large flow rates is necessary, e.g. gas exchange processes, steam cooling or dust suppression. Lechler cluster head nozzles have decisive advantages because of overlapping hollow cones, which form a fine full cone atomization with an increased droplet surface area.
These very fine droplets cannot be achieved by a single-orifice spray nozzle of the same flow rate size. The increased droplet surface area of the atomized liquid provides greater efficiency in gas treatment and cooling applications.
