Efficient and discreet, the Helty Flow 120 HRV with its recessed wall installation system is the optimal choice to ensure a constant air renewal in medium-sized spaces, contributing to indoor well-being and comfort throughout all seasons.
Recessed HRV ideal for renovations and energy upgrades
Easy to install and aesthetically appealing, the Flow120 HRV is the new recessed wall-mounted ventilation unit that minimizes space requirements with a width of only 16 cm and a height of just 92 cm. The choice between different cover types (paintable sheet metal, white or black plexiglass) allows Flow120 to harmoniously integrate into any environment, from domestic spaces to offices. The capability for recessed wall installation also allows for working with walls as thin as 34.5 cm.
Quiet, attentive to thermal comfort and savings
With a sound power level below 40 dB(A) at working airflow (60 m³/h) the Flow 120 HRV is discrete and harmonious in every context, thanks to the operational silence. The thermal performance is remarkable as well, thanks to the enthalpy heat exchanger that ensures an 88% heat recovery rate. The free-cooling function also contributes significantly to energy efficiency: when external conditions are favorable, the unit contributes to heating or cooling without additional costs, reducing the load on existing air conditioning systems.
Multiple functions available for uncompromised fresh air
The decentralized mechanical ventilation unit, Flow120 Helty, is available in a standard version, equipped with a hygrometric sensor. The Pure version enhances the machine’s capabilities by adding a CO2 + VOC sensor that detects excessive carbon dioxide and airborne pollutants, automatically adjusting the operation of the HRV unit to ensure optimal indoor air quality conditions. Unit control through the Air Guard app, based on home Wi-Fi, also provides convenient accessibility and ease of use.
Flow C120: the first ductable Helty HRV
The ductable Flow C120 model offers even greater versatility in HRV system design, enabling the servicing of multiple rooms within the living unit. This version, with ducted supply and exhaust flows of up to 8 meters, allows for separate control of air extraction and supply in the installation areas. For instance, it can extract exhaust air from a bathroom and introduce fresh air into an adjacent bedroom or another room. A smart solution, ideal for three-room apartments, to reduce HRV system implementation costs and manage air exchange in adjacent rooms with a single decentralized ventilation unit.
