Reason for us to develop a new and unique ventilation concept: Multi Air Supply. That makes it possible to install HRV in any property. The innovative ventilation system Multi Air Supply includes the smart Indoor Mixfan with active CO2control that ensures optimum air quality in every room. Innovative ventilation concept The innovative ventilation concept Multi Air Supply is based The quantity of fresh outdoor air that the HRV unit needs to on a central balanced heat recovery system (HRV). A special supply to keep the air in the hall fresh, is also CO2 controlled. feature is that the fresh air is freely blown into the central That way the air quality in all habitable rooms remains optimal. hall, landing or stairwell. So no need for supply ducts. Exhaust provisions in the kitchen, bathroom and toilets are A compact, CO2-controlled Indoor Mixfan in each habitable made with conventional ducts. The HRV unit extracts the heat room removes the ‘stale’ air from the room to the stairwell. from the exhaust air before it is directly discharged to the Fresh air from the stairwell enters the room through the gap Existing buildings and new projects The Multi Air Supply system can easily be installed in certificate of equivalence.
