Helty Decentralized Ventilation: Italian Heat & Moisture Recovery Systems for Homes and Offices
Helty (Italy), an Alpac Group brand, specializes in advanced decentralized mechanical ventilation with heat recovery (MVHR/HRV). Helty systems provide a complete and balanced indoor air exchange without requiring complex, invasive ductwork across the entire building.
Key Advantages of Helty Systems:
Enthalpy and Sensible Heat Exchangers: Recover up to 91–92% of thermal energy while maintaining optimal indoor humidity during winter without overdrying the air, eliminating the need for a condensate drain in enthalpy versions.
Advanced Air Filtration: Built-in ePM2.5 65% (F7) and ePM1 80% (F9) filters effectively block fine dust, pollen, allergens, and smog.
Radon Mitigation ("R" Series): Specialized models featuring adjustable airflow imbalances and optional Radon Monitors to actively reduce hazardous radon gas concentrations.
Acoustic Comfort: Whisper-quiet performance with minimum noise levels starting from 17.5 dB(A), ensuring unnoticeable operation.
Smart Control: Full integration with the Helty Home App, the HCloud web platform, and automated operation modes driven by humidity, CO2, and VOC sensors.
