Lechler - Full Cone Nozzles

Lechler full cone nozzles have an extraordinary uniform liquid distribution over the whole circular impact area.

The high .

The high precision of distribution is achieved by orienting the liquid inlet to the centre of the swirl chamber of the nozzle.

The optimized x-style swirl insert ensures a high operating safety due to its large free cross-sections.

Axial-flow full cone nozzles are available with different spray angles and in many flow rates. Therefore, matching to specific

service conditions is possible without any difficulties.

• Extremely uniform liquid distribution
• Wide flow rate range
• Large number of available spray angles

Tangential-flow full cone nozzles are, for instance, particularly suited for closed-circuit spraying of liquids with a high quota of solid matters, or for fire fighting applications.

The atomizing fluid is tangentially supplied to a swirl chamber, where it is put into rotation.

Tangential-flow full cone nozzles are free of swirl inserts.

Hence, they are not at all prone 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.

• Reliable in service
• Non-clogging
• Stable spray angles, unaffected by transient pressures
