Ekolser-CYCO Hollow Cone Nozzles project a ring-shaped circular spray pattern with fine atomized droplets concentrated along the outer perimeter. The void in the center of the spray cone maximizes the total surface area exposure of liquid droplets to the surrounding gas stream. This unique property enables rapid liquid evaporation, efficient mass transfer, and optimal thermal exchange. Ekolser-CYCO hollow cone nozzles are the ideal engineering choice for evaporative gas cooling, air humidification, dust suppression curtains, chemical gas scrubbing, and delicate agricultural or industrial atomization processes.
