Helty FlowEASY Plus (Version Enthalpy Shutter) Decentralised Heat Recovery Unit | Compact wall ventilation System
Helty FlowPLUS Enthalpy (Shutter) Wall-Mounted MVHR Ventilation Unit
A premium decentralised wall-mounted MVHR unit from the Italian manufacturer Helty. Equipped with a high-efficiency counter-flow enthalpy heat exchanger, it ensures continuous air exchange with up to 91% thermal energy recovery while maintaining natural indoor humidity levels without requiring a condensate drain. Features advanced multi-stage filtration (F7 + G4) that captures pollen, fine dust, and allergens for cleaner indoor air.
The Shutter model differs from the base STD version by featuring an automatic damper that seals the ventilation duct when the unit is switched off, preventing cold air from entering.
Core Advantage: Maximum Comfort, Smart Control, and Quiet Operation
-
Premium Ventilation Performance: Flagship model featuring an increased airflow rate up to 42 m³/h with 4 operating speeds + Night mode + Hyperventilation mode.
-
Minimal Structural Impact: Clean installation without requiring bulky ductwork throughout the room—only requires drilling two small 80 mm diameter holes through the exterior wall (2x Ø80 mm).
-
Enthalpic Heat & Moisture Recovery: Counter-flow enthalpy heat exchanger recovers up to 91% of thermal energy while maintaining optimal indoor humidity, preventing dry indoor air in winter and eliminating the need for a condensate drain.
-
Smart Control & Monitoring: Automatic indoor climate management via an integrated hygrometric sensor (humidity sensor), Helty Home mobile app (Wi-Fi), IR remote control, and Modbus RTU rs485 support.
