Greenheck’s Sync-180 is a low-profile, high-efficiency, cold-weather-rated ERV that offers a 75- to 200-cfm range with three high-speed options. Each airstream has an independent centrifugal blower powered by a direct-drive EC motor, which adjusts speed with increased static pressure to maintain flow rates as the filter or core gets dirty. Pairing with the company’s PrecisionSync Controller allows the unit to measure the airflow capacity of the installation and dial-in a precise airflow. Available online for $1,400. greenheck.com
