Greentek units feature external balancing taps and an optional commissioning kit (463311) for faster, easier airflow balancing across multiple buildings. Door Pressure Taps close Greentek products feature factory-sealed, maintenance-free motors that run quietly and efficiently, using as little as 58 watts on select models (PROFILE 0.8E). Motors The PREMIER series designates the supply fan to shut down when outdoor temperatures drop below 23°F (-5°C), preventing frost buildup. Supply Fan Shutdown Defrost Cycle Greentek HRVs use aluminum cross-flow exchangers for efficient sensible heat transfer, while our ERVs feature washable polymer cores for high total recovery and lasting performance. Recovery Core PREMIER uses easy-connect ports to make installation simple and build a strong connection for airflow. Side-ported Connections Includes chain mount assembly, long bracket assembly optional.
