Breakthrough HRV/ERV Technology

All Zehnder HRVs/ERVs are characterized by a high level of heat recovery, quiet, energy-efficient DC-motors, rugged controls and simple operation. The devices can be used for single-unit as well as multi-family homes. In addition, the devices can be used for small commercial applications, classrooms, nursery school facilities, and retirement communities. The systems are used in both retrofit and new construction projects.
Zehnder’s ComfoAir 350 HRV with its counter flow heat-exchanger recovers over 90% of the room temperature. As a result even during a cold winter day, the incoming fresh filtered air into the house is typically within 2-3 degrees from the inside temperature.
