The recessed ventilation system that is there but out of sight
An invisible HRV, which combines excellent air exchange and purification performance with zero footprint: “disappearing” inside the wall, Flow40 does not require piping or false ceilings and leaves only the front cover visible.Single-room ventilation allows you to adjust functions and performance based on the actual needs of each room, ensuring efficient system management and personalised comfort.
The invisible solution!
Advanced air filtration
TUV certified 91% heat recovery
Indoor air quality control sensors
Flow40 offers all the benefits of Heat Recovery Ventilation, simplifying the design and minimising the aesthetic impact, dimensions and maintenance.
Ideal for renovations and energy upgrades
The use of prefabricated components and the absence of air distribution networks makes this wall-recessed HRV system particularly easy to design and versatile to install during residential renovation or energy upgrading.The Flow40 ventilation system can be installed on walls of variable thickness (minimum 335 mm), both with plaster finish and with insulation.
Optimal thermal and acoustic comfort
The special cross-flow enthalpy heat recovery system allows Flow40 to recover up to 91% of the heat contained in the extracted air flow, avoiding the energy losses that would occur with the introduction of cold air. By also recovering some of the latent moisture content, it ensures the intake air is never too dry. Acoustic comfort is assured thanks to advanced facade noise abatement and sound pressure levels of just 18dB at first speed. The absence of air ducts avoids acoustic bridges and noise transfer between rooms.
Protection against condensation, mould and pollutants
The HRV unit is also equipped as standard with a hygrometer for continuous monitoring of relative room humidity allowing for an automatic and more efficient regulation of forced ventilation to combat condensation and mould. The CO2 and VOC sensor and monitoring app (available in the Pure version) mean extensive control of indoor air quality at any time of the day.
New Flow 40 windows-side
Helty Flow 40 HRV with grilles exit on the side of the window frame is the innovative concealed solution that is even more invisible and discreet, thanks to the possibility of managing the grille exits directly in the window shoulder. A system that has no visible impact on the facade, preserving the integrity of any type of building. Flow 40 with light exit is an interesting and versatile option for major renovations and new construction sites in contexts that require special attention to architectural aesthetics. The system can also be planned in the construction phase alone, to be completed at a later date as required.
