The Bosch Vent 5000 C recuperator is a device that allows comfortable ventilation of buildings with simultaneous heat recovery. Device with a nominal air flow of 230 m³/h. High heat recovery efficiency, even above 90%, allows for significant savings in heating costs and at the same time ensures fresh and clean air in the rooms. In addition, thanks to constant ventilation, the recuperator has a built-in by-pass, thanks to which it is possible to blow cooler air in the evenings. The interior of the device is made of EPS - expanded polystyrene - provides very good thermal and acoustic insulation. The built-in by-pass allows the building to be cooled in the summer. The built-in pre-heater prevents the formation of ice on the heat exchanger and ensures stable operation all year round. Possibility of using additional sensors: moisture, carbon dioxide and VOC - pollution sensor, improving air quality. Filter replacement signaling. Installation possible on the wall or on the floor.
