Overview of all hollow cone nozzles

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.

Eccentric-flow hollow cone nozzles 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.
