Radon HRV
Helty’s innovative Flow R line proposes a series of decentralised HRV solutions dedicated to radon risk mitigation: different HRV models designed to respond effectively to both residential and tertiary risk reduction needs.

HRV for smart radon risk management
The Helty Radon Line products are designed to provide an effective and minimally invasive solution in radon risk management. HRV units can be remotely programmed, setting customised operating scenarios; or they can be calibrated on-site, depending on the radon gas concentration detected in the environment.
Thanks to the WiFi cloud panel, the ULTRA-R, 400-R and 800-R versions allow remote management by the Helty Home App, or directly from the HCloud web platform. The Radon Scenarios option allows for the best possible management of radon risk mitigation through the customised setting of the HRV units: by programming the unbalance of the machine, it is possible to diversify the intake and extraction flow rates, maintaining the unbalance settings at different speeds.
For these models the Radon Monitor is also available on request, a Radon presence sensor that allows active monitoring of the gas, enabling an adaptive and automatic response based on user-programmable intervention thresholds.
Home, school, offices, shops: a complete range of solutions
The HRV radon Flow R line allows you to operate in different contexts: from residential to tertiary, schools and shared work spaces. A range of punctual solutions that are easy to install and configure, with top performance not only in terms of radon risk containment, but also in terms of filtration and air exchange, silent operation, and heat recovery.


Customised settings to meet every need
The new line of HRV Helty Flow-R systems stands out for its flexibility in configuring the operation of the ventilation unit, allowing the most effective strategy to be set through differential regulation of the flow rates treated. This allows different containment solutions to be adopted, so as to prevent radon gas from entering the living space and keep its concentration within the limits defined by the project.
