Hygienic design

The open structure allows easy and efficient cleaning after each use. The design avoids flat surfaces to prevent the accumulation of water after washing. The electric and electronic components are contained in sealed cabinets and are completely protected against water infiltration.

User-friendly software interface

The user-friendly interface makes programming quick and intuitive. Over 100 programs can be stored. The individual weight of all products that pass over the lead cell can be stored in a database and extracted for production reports, using the option for the MATRIX CG software package. MATRIX has the option to connect printers to print customized labels.

Low noise

The compact grading machine has the lowest noise level during operation. This creates a pleasant environment for operators.

Easy installation

The compact grader comes as one premounted unit and the installation is 'plug and play'. Only air and electricity need to be connected.
