Lechler full cone nozzles excel in applications that require uniform liquid distribution across a circular or square area. Applications include product coating, product cooling, and stationary washing or rinsing. Lechler offers two styles of full cone nozzles: axial and tangential.
Axial full cone nozzles
Lechler low-to-medium flow axial full cone nozzles incorporate a modified x-style vane, promoting more precise distribution and constant pattern width. These axial full cone nozzles have a straight-through flow line from input to output. The vane separates the incoming liquid into two paths which cross near each other (hence the “x-style”). The two flows reunite before exiting through the nozzle orifice. The result is a uniform spray distribution throughout the cone with consistent spray angles.
The high capacity full cone nozzles have a somewhat different vane design. The Lechler CenterJet nozzles utilize a turbine style center of three or more blades for uniform coverage and thorough atomization. The CenterJet is an excellent economical alternative to our standard x-style axial full cones where the larger free passage and spray angle consistency are not required. Lechler’s Free Spray full cone nozzles utilize a one-piece design with non-removable vanes to provide excellent spray distribution of large droplets throughout the suggested 1/2 psi to 60 psi operating range. Large open orifices accommodate large particulates for clog-free performance.
Tangential full cone nozzles
Tangential full cone nozzles are particularly suited for closed-circuit spraying of liquids with a high quota of solid matter, or for firefighting applications. The atomizing fluid is tangentially supplied, or at right angles, to a swirl chamber where it is put into rotation. Tangential full cone nozzles are free of swirl inserts. Hence, they are resistant to clogging. The full cone spray is obtained with the aid of specially arranged grooves, milled into the nozzle bottom, which cause an adequate part of the rotating liquid flow to diverge to the center of the swirl chamber. Thereby an extremely uniform area distribution of the sprayed liquid is achieved.
Two other types of nozzles that create full cone patterns are:
