Demand-Controlled-Ventilation Controls

Controls maximize efficiency while maintaining indoor air quality by  automatically adjusting ventilation rate to or from a space.

Vari-Green 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 volatile-organic-compound control. Via programmable set points, the control automatically adjusts the fans’ ventilation rate to or from a space. A constant pressure control monitors 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. —Greenheck
