The fresh air heat recovery unit ensures a constant air exchange in residential, educational buildings and office spaces without the active participation of users and with closed windows. Thanks to built-in filters, fresh air enters the room purified and exhaust air which is saturated with carbon dioxide is discharged outside.
Due to the heat storage in the ceramic heat exchanger of the fresh air heat recovery unit, fresh air enters the rooms heated even in the cold winter. Thus, it is possible to completely eliminate the airing with open windows, with no loss of heat, as well as limiting the entry of dust, carbon monoxide and noise from the street.
The minimum power consumption of 7,7 W per hour will have virtually no impact on utility bills. Simple and quick installation without dust and dirt allows you to equip any non-industrial room and provide people in it with fresh air without loss of heat.
A high-quality Austrian ceramic heat exchanger, due to its optimal thermal-physical properties and improved cell structure, provides heat recovery (return) efficiency of up to 94%. The ceramic heat exchanger does not undergo freezing and performs its functions without affecting the heat recovery efficiency, even at a temperature of -50°C. No condensation occurs.
Ventoxx decentralized heat recovery units can be operated by remote control or the Ventoxx Twist wall-mounted control unit (available separately). The devices are equipped with replaceable and washable G3 filters, which must be washed once a quarter and completely replaced every 2 years.
