Zephyr Plus is a decentralized heat recovery ventilation device designed to provide continuous fresh air in residential and light commercial environments without the need for a central ventilation system.
By combining energy-efficient airflow management with heat recovery technology, the system reduces heat loss while maintaining a healthy indoor climate.
Zephyr Plus uses heat recovery technology to transfer thermal energy from outgoing air to incoming fresh air. By reusing this energy, the system helps maintain indoor temperature stability while continuously supplying fresh air. This approach improves indoor air quality while reducing energy consumption and supporting more efficient building performance.
During operation, Zephyr Plus alternates between extracting stale indoor air and supplying fresh outdoor air. When indoor air is exhausted, the ceramic heat exchanger captures and stores its thermal energy. After a short cycle, the airflow direction reverses and fresh outdoor air passes through the same ceramic core.
The stored heat energy is then transferred to the incoming air, pre-conditioning it before it enters the room. This alternating airflow process allows the system to continuously refresh indoor air while significantly reducing heat loss.
