Ventilation controls – Greenheck

May 6, 2013

A selection of Vari-Green® controls is available from Greenheck. The controls maximize the energy efficiency of ventilation systems in a variety of applications when used in conjunction with Greenheck’s Vari-Green motor.

For applications required to maintain indoor air quality, Greenheck offers a temp/humidity control or a VOC control. Via programmable set points, the control automatically adjusts the fan’s ventilation rate to or from the area by increasing or decreasing fan speed. A constant pressure control can help monitor static pressure in demand controlled ventilation applications with multiple pressure changes, or velocity pressure where a constant CFM level within a duct needs to be maintained. Transformers, remote dials and two-speed controls are also available.
