Hollow cone nozzles

Two types of hollow cone nozzles are available:

Axial-hollow cone nozzles
  • Finest drop particles
  • Narrow free cross-sections
  • Maximum spray angle 90°

Eccentric-flow hollow cone nozzles
  • Coarser droplets than axial-flow hollow cone nozzles
  • Large free cross-sections
  • Wide spray angles up to 130°
  • Self-cleaning, non-clogging
 

Axial-flow hollow cone nozzles

Wherever a fine, uniform hollow cone spray 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 with in a remarkably narrow drop let spectrum. This creates extraordinarily favourable conditions for mass transfer.

Tangential-flow hollow cone nozzles

Tangential-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°. Tangential-flow hollow cone nozzles are of a self-cleaning design, offering a high operational safety, even at rather poor water conditions. Typical applications for tangential-flow hollow cone nozzles are: air humidification in air conditioning systems or gas cleaning in chemical and environmental engineering installations.
