greenBOX Nxt
Ideal for factories with up to 75 workstations.
The greenBOX Nxt intelligently controls multiple dust, fume, or mist extraction systems as well as multiple fans via multiple Variable Frequency Drives. It can manage many ventilation systems with up to 75 gates. This control system allows users to easily expand and add more systems in the future. It is remotely accessible, over internet upgradable, and cost-effective. The system is designed to be fully automated, so users are expected to just use their workstations.
Product Description
The brain of the Ecogate system, the greenBOX, is a state-of-the-art control unit designed to optimize your dust/fume/mist collection system resulting in electricity savings between 50% to 75%.
This control unit can manage your entire dust collection system: it opens and closes workstation gates, starts and stops ventilation fan(s) and dust collectors, adjusts the fan(s) speed via Power Master VFD, and maintains minimum transport air velocities in the duct system.
By utilizing real-time air velocity, volume, and pressure measurements, it continuously monitors your machines' activities to determine the airflow requirements. Air velocities, volumes, and pressures are measured at gates, calculated at branches, and assessed at the system level.Tech Specs
