All controlling systems for bead production are incorporated in the control unit. Vibration frequency,
light intensity, electrostatic dispersion and heating, are controlled on the touch screen. Air pressure
is regulated with the pressure regulating valve. The pressure is electronically indicated on the touch
screen. The pumping rate of the polymer mixture is controlled with the liquid flow regulating valve.
The integrated stroboscope lamp allows real time jet breakup control. The main switch is on the front
panel. The bead producing unit is attached to the carrier plate with two screws (M3×25).
