Ecogate’s NEW energy saving gate for industrial ventilation systems measures air velocity, pressure and volume. This information is transmitted to the Ecogate greenBOX® MasterTM where it is used as an integral part of system control and balancing. An Ecogate® system equipped with the NEW velocity measuring gate and greenBOX® MasterTM automatically re-calibrates after changes to the dust collection system to ensure continued optimal energy efficient operation over the life of the system. This technology will also ensure that minimum transport air velocity is maintained after system changes. It also provides continuous real-time awareness of air velocities throughout the dust collecting system.
