Greenheck’s new high-performance residential energy recovery ventilators (ERVs) provide balanced ventilation that improves energy efficiency and ensures multifamily projects meet code and exceed indoor air quality expectations. Four models—ASSURE120, SYNC110, SYNC180 and SYNC270—are available with a variety of options and accessories and all offer Home Ventilating Institute-certified airflow. ASSURE120 and SYNC110 offer a 50-130 cfm operational range in a compact low-profile design that simplifies installations with limited mechanical space, such as bulkheads and drop ceilings. SYNC180 and SYNC270, which are 75-200 cfm, are cold-weather certified ERVs. When paired with PrecisionSYNC control, the ERVs allow for measurement of the maximum airflow capacity of the installation and precisely adjust airflow to meet design and code requirements. All models include a Total Recovery Core that transfers heat and moisture between two crossflow airstreams without allowing cross contamination.
