FLOW 100

Concealed ventilation system designed to meet all air exchange and comfort needs in medium-sized environments.

Top-class ductless ventilation

With a variable air flow rate of up to 100 m³/h and a category F7 external air filter, the Flow100 recessed HRV provides excellent levels of refreshed and purified air in individual environments requiring an higher ventilation rate.All without requiring the design or installation of ducts or the the construction of technical compartments or false ceilings: with these concealed mechanical ventilation systems the system is integrated into the house perimeter, rendering it invisible.

VMC Flow 100: gestione smart e risparmio energetico

Energy-saving HRV with smart management

Decentralisation of the system with several variable flow ventilation units allows for differentiated and variable air exchange management according to the needs of the individual environment.
The “room-by-room” adjustment can be fully automated based on the humidity, CO2 and VOC values detected by the sensors fitted on the models.The cross-flow enthalpy heat recovery system ensures the Helty Flow100 provides 87% heat recovery efficiency.
The system can also provide a zero-cost contribution to the cooling or heating of environments in the cooler summer evenings and between seasons. When required, the automatic free cooling deactivates heat recovery and delivers cooler or warmer air.

Whisper-quiet ventilation, day and night

The Helty Flow100 ensures an optimal balance between forced ventilation capacity and low operating noise under all conditions.
A special night function – activated via the panel, infrared remote control or the Air Guard App – slows the fans and turns off the LED lights to ensure a minimum and imperceptible air exchange even at night or at times that require maximum concentration and absolute silence.

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.

Yes, proper ventilation of all spaces and rooms is essential for removing excess moisture and preventing condensation and mould.

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.

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.
