Greenheck has expanded its line of Dedicated Outdoor Air Systems (DOAS) for high percentage and 100% outside air. Pre-engineered rooftop ventilator models RV-110 and RVE-180 with energy recovery offer capacities up to 18,000 cfm, up to 70 tons of cooling and 1200 mbh indirect gas-fired heating.
Both models feature an upgraded controls platform with a web user interface that comes as standard. The new web user interface (UI) provides an overview graphic of the unit operation and allows the controller menus to be accessed and adjusted from the web UI. The factory-programmed, wired and tested controller can operate as a stand-alone unit or integrate with a Building Management System (BMS).
Temperature and humidity control
Factory-mounted Variable Frequency Drives on models RV-110 and RVE-180 control airflow. A digital scroll compressor provides tight temperature and humidity control, and a 10:1 high turndown furnace provides precise temperature control. All are standard features with packaged DX cooling and indirect-gas heating on these new models.
Featuring two-inch double-wall construction and R13 thermally broken foam insulation, Greenheck DOAS units meet the demands of heating, cooling, dehumidification, and ventilation requirements.
