SONAR SYSTEM

The Sonar technology generates acoustic waves, whose geometrical propagation is close to the optical geometrical propagation of straight beams. A contaminant with different structure and density than the fibrous material reflects the acoustic beam towards a receiver, which activates the corresponding solenoid valve for the rejection of the contaminant into the waste container.

HDS OPTICAL SYSTEM

The HRS Optical technology detects the contaminant, having a different light absorption index than the fibrous material, by means of high resolution sensors array with lenses placed in both sides of the measuring channel.
A solenoid valve is then activated for the rejection of the contamination into the waste container.
