Greenheck Expands Energy Control Product Line with the Vari-Green(TM) Drive

Press release date: May 23, 2016

GB with VGD open3

Greenheck’s line of Vari-Green™ energy control products has expanded with the introduction of the Vari-Green Drive (Model VGD-100), a factory-mounted and wired variable speed control for three-phase motors up to 10HP. Traditionally, most VFDs are mounted away from the fan motor, and as a result, voltage spikes can occur. Additional devices such as filters and reactors may need to be installed to mitigate possible damage to the motor. 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 preprogrammed drive uses R3 filtering technology to significantly reduce electrical harmonics back into the building. No field installation or start-up is required saving contractors time. The Vari-Green Drive optimizes energy savings and efficiency of ventilation systems in a variety of applications.

Greenheck is the worldwide leader in manufacturing and distributing air movement, conditioning and control equipment.
