Starmanifold Starwheel Injection System

The Starwheel and Starmanifold injection systems designed by Definox allow for customizable multi-points injection of flavors, colorants and additives into the fluid process, closest to the fluid stream. According to the injection needs, the valves can be put in place or taken out quickly.


  • Greater industrial flexibility with faster
  • Reduced maintenance time
  • Modular system, easily modified thanks to the clamp connections
  • Customized solutions matching process configuration
  • Optimum availability of the lines
  • Compact system, with less than 150 mm needed for 4 injection points
