Nordson Corporation’s Spectrum Powder Feed Center is the company’s next generation of feed center technology. It is a complete, closed-loop powder management system that is designed to provide a clean operating environment and optimum powder handling conditions, while reducing operator interaction.

Available in configurations for both venturi and dense phase (HD) powder application systems, the new feed center embodies lean process control for a solution that is clean, efficient and precise.

The closed-loop system ensures powder containment during operation and color change for a cleaner, safer and more productive environment. It incorporates a variable frequency ultrasonic sieve, fitted as standard, to automatically condition powder and eliminate problematic screen blinding.

Other features include:

  • A proprietary cylindrical hopper design and centrifugal high-pressure cleaning to efficiently clean the entire area, eliminating corners in which powder could be trapped.
  • Three level sensors with visual/audible alarms, optimizing powder levels and the flow rate from each gun.
  • Fresh powder is automatically fed in to the system, direct from the box, to support any production run and further reduce operator intervention.
  • A digital touchscreen interface guides the operator through the color change process, reducing error and skill dependency. Tool-free operation provides a simple and intuitive process for every operator on every shift.  All powder management and system controls are consolidated in one place, reducing factory footprint and enhancing operator ergonomics.

The feed centers are available in configurations that utilize two different pump technologies, The Spectrum VT Feed Center is designed for venturi-based systems; and the Spectrum HD Feed Center supports dense phase powder coating application systems.
