Casale proprietary vibrating heads are specifically designed to reduce the area and the height of the prilling tower with great advantage on the capex cost.
One of the advantage of Casale prill head is that the jet break up is by mechanical vibration and can be specifically tuned to be near the natural break up frequency. In this way the harmonics are suppressed, and the resulting droplets are monodispersed.
Thanks the vibration, the ANS flow through the head can be increased keeping a tight particle size distribution. This allows to reduce the dimension of the prill tower are the prill temperature at the outlet is more homogeneous. Moreover, thanks to a careful design of the head the prills trajectories can be optimized to use the prilling tower area in the most effective way, reducing also the prill tower height.
