The Bosch Vent 5000 C heat recovery unit is a device that allows for comfortable building ventilation with simultaneous heat recovery. The device has a nominal airflow of 350 m³/h. High heat recovery efficiency, even above 90%, enables significant heating cost savings while always providing fresh and clean indoor air. Additionally, thanks to constant ventilation, the heat recovery unit features a built-in bypass, allowing cooler air to be supplied in the evenings. The interior of the device is made of EPS (expanded polystyrene), ensuring excellent thermal and acoustic insulation. The built-in bypass allows the building to be cooled in the summer. The integrated pre-heater prevents ice formation on the heat exchanger and ensures stable operation throughout the year. Possibility of using additional sensors: humidity, carbon dioxide, and VOC (pollutant sensor), which improve air quality. Filter replacement indicator. Can be mounted on the wall or floor.
