Can CMV resolve my condensation and mould problems?
Yes, proper ventilation of all spaces and rooms is essential for removing excess moisture and preventing condensation and mould.
Flow MANHATTAN
Decentralised HRV for installation in the external insulation. Zero impact on the facade, maximum silence and internal comfort.
The new HRV for building upgrades with exterior insulation
Helty Flow Manhattan revolutionises decentralised mechanical ventilation by offering a completely new installation mode. The dual flow decentralised HRV unit is concealed within the exterior insulation, meaning zero aesthetic. The Ideal solution for building renovation and energy upgrading with envelope insulation.
Patented HRV system
Zero aesthetic impact on the facade
Air flow rate up to 70m³/h
Optimal acoustic comfort
Price upon request
Helty Flow Manhattan is the innovative HRV solution for energy upgrades that require exterior insulation, offering an optimal balance between air flow and acoustic comfort.
The only HRV hidden within the exterior insulation
Helty’s intense research and development work has allowed us to engineer and patent an innovative solution tailored to the ongoing challenges in the building upgrade market.
A unique combination of reduced thickness and high performance means the Flow Manhattan air treatment unit is hidden “under the skin” of the exterior insulation. The unit can be Installed entirely from the outside on both sides of the window hole and is compatible with all insulation types.
Zero-impact design
The building’s architectural profile is maintained thanks to low-impact ventilation grilles fitted in the window hole, without any effect on the building facade. The impact on internal space is also close to zero with just one small, minimalist-design wall diffuser for air intake and extraction.
Wellness, comfort and silence
With variable air flow rates up to 70 m³/h, Flow Manhattan meets the air exchange and purification needs of individual rooms, including medium-sized spaces. An F7 filter purifies the air of PM10 and PM2.5 particulate matter, bacteria and pollen. Moisture and pollutants are removed thanks to the “room on room” balanced ventilation. All with an exceptional operating silence that improves comfort in living and working environments. Sound pressure level is 16.5 decibels. The noise reduction of the façade is certified equal at 51 dB.

Frequently asked questions
How does a decentralised dual-flow CMV system work?
A decentralised dual-flow CMV allows for continuous replacement of extracted stale air with fresh air intake, meaning better results in terms of energy efficiency and purification of incoming air.
Is CMV eligible for the 110% Superbonus deduction?
CMVs are eligible for the 110% Superbonus deduction if the system is intended to prevent the formation of mould or condensation and the problem is not otherwise preventable. CMVs are also eligible for the incentive when used to replace a winter air conditioning system with an air system and are closely integrated into the original.
