Variable speed control for 3-phase motors
Greenheck’s Vari-Green Drive Model VGD-100 is a factory-mounted and wired variable speed control for 3-phase motors up to 10 hp. Internally mounted within the fan housing, the Vari-Green Drive virtually eliminates voltage spikes that can contribute to motor performance issues and motor failure. The pre-programmed drive uses R3 filtering technology to reduce electrical harmonics back into the building. No field installation or start-up is required. The Vari-Green Drive optimizes energy savings and efficiency of ventilation systems in a variety of applications.
