    Full cone nozzles

    Axial-flow full cone nozzles

    Lechler full cone nozzles havean extraordinarily uniformliquid distribution over thewhole circular impact area.The high precision of distribu-tion is achieved by orientingthe liquid inlet to the centre of the swirl chamber of thenozzle.The optimized x-style swirlinsert ensures a high opera-ting safety due to its large freecross-sections.

    Tangential flow full cone nozzles

    Tangential-flow full cone nozz-les are, for instance, particu-larly suited for closed-circuitspraying of liquids with a highquota of solid matter, or for firefighting applications. The ato-mizing fluid is tangentiallysupplied to a swirl chamber,where it is put into rotation.Tangential-flow full cone nozz-les are free of swirl inserts.Hence, they are not at all pro-ne to clogging. The full conespray is obtained with the aidof specially arranged grooves,milled into the nozzle bottom,which cause an adequate part of the rotating liquid flow todiverge to the center of the

    Cluster Head Nozzles

    Lechler cluster head nozzlesachieve a very large surfaceof the sprayed liquid byadding various finely atomi-zing single nozzles.Whenever a fine fog-like fullcone atomization with relative-ly large flow rates is neces-sary, e.g. gas exchange pro-cesses, steam cooling or dustsuppression, Lechler clusterhead nozzles have decisiveadvantages: overlapping hol-low cones form a fine fullcone atomization with anincreased droplet surfacearea. These very fine dropletscannot be achieved by a

    Axial-flow full cone nozzlesare available with differentspray angles and in may flowrates. Therefore, matching tospecific service conditions ispossible without any difficul-ties.
