Silent and efficient, Helty Flow 70 HRV is ideal for managing continuous air exchange even in single medium-sized environments and improving health and comfort, whatever the season.
Recessed HRV ideal for renovations and energy upgrades
The Flow70 HRV system allows integration of a controlled mechanical ventilation system with advanced heat recovery and air filtration during renovation or into new builds where there is no space for air ducts, ceiling lowering or technical rooms.Flow70 is fully concealed, leaving only the elegant cover visible. The cover, available in metallic or in white or black plexiglass, adapts to any space.
Fresh and healthy air without wasting energy
Variable flow ventilation lets you optimise air exchange based on the needs of each individual environment. The Helty Flow70’s cross-flow enthalpy heat recovery system recovers up to 90% of thermal energy by transferring it from the extracted air to the intake air. Free-cooling operation is another important factor in energy efficiency and can be managed automatically with the heat exchanger by-pass. When the outside conditions are right, the unit contributes to heating or cooling at no extra cost by relieving the load on the existing air conditioning systems.
Silent HRV system with advanced acoustics
Silent operation and insulation from external noise are essential considerations when selecting a concealed ventilation system. Helty Flow70 offers quiet running and advanced sound insulation. The special EPS housing is designed and built to ensure a certified facade noise reduction of 54dB.
An ally against moisture, CO2 and pollutants
Humidity has a strong influence on the feeling of well-being and livability at home, and Helty Flow70 is fitted with an integrated sensor to detect humidity levels.A CO2 and VOC sensor (available in the Flow70 Pure model) warns of excess carbon dioxide and pollutants in the air, intelligently and automatically adjusting the operation of each HRV to ensure optimal indoor air quality.
