Concentric nozzle system: Concentric nozzle system for creating core-shell capsules (diameter 200 – 2000 µm).

Flow vibration nozzle: Airflow-assisted nozzle system for producing beads (diameter 80 – 1000 µm) from highly viscous polymers.

Big capsules nozzle: Nozzle system for production of large core-shell capsules (diameter 2 – 4 mm) by means of drop separation process.

Nozzle heating: The integrated nozzle heater expands the breadth of applications. It enables the processing of melts such as wax or gelatine.
