Lechler - Hollow Cone Nozzles
Two types of hollow cone nozzles – the axial-flow hollow cone nozzles and the tangential-flow hollow cone nozzles – are available for selection:
A decision is made between axial hollow-cone nozzles and tangential-flow hollow-cone nozzles. With the axial hollow-cone nozzles, the liquid is supplied axially. With the tangential-flow hollow-cone nozzles, a tangential liquid inlet into the swirl chamber of the nozzle causes the liquid to be atomised to rotate.
- Coarser droplets than axial-flow hollow cone nozzles
- Large free cross-sections
- Wide spray agles up to: 130°
- Self-cleaning, non-clogging
Eccentric-flow hollow cone nozzles provide a very uniform hollow cone spray thanks to a particular flow geometry. Liquid is put into rotation by an eccentricity arranged liquid inlet. Thereby a very uniform liquid distribution is achieved with spray angles up to 130°.
Eccentric-flow hollow cone nozzles are of a self-cleaning design, offering a high operational safety, even at rather poor water conditions. Typical applications for eccentric-flow hollow cone nozzles are: air-humidification in air conditioning systems or gas cleaning in chemical and environmental engineering installations.

Axial-hollow cone nozzles
- Finest drop particles
- Narrow free cross-sections
- Maximum spray angle: 90°
Wherever a fine, uniform hollow cone is needed, e.g. for cooling and cleaning of gas, absorption processes, dust control, product dampening, oil spraying and air humidifying, axial-flow hollow cone nozzles have proved very efficient.
The spiral grooves in the swirl inserts ensure an efficient whirling of the liquid. As a result, the contact surface of the atomized liquid is significantly increased within a remarkably narrow droplet spectrum. This creates extraordinarily favourable conditions for mass transfer.
