Helty FlowEASY Plus (Version Sensible Shutter + Preheating) Decentralised Heat Recovery Unit | Compact wall ventilation System

Helty FlowPLUS Sensible (Shutter + Preheating) Wall-Mounted MVHR Ventilation Unit A premium decentralised wall-mounted MVHR unit from the Italian manufacturer Helty. Equipped with a high-efficiency counter-flow sensible heat exchanger, it ensures continuous air exchange with up to 91% thermal energy recovery. Designed for effective heat recovery in spaces where moisture exchange is not required, with condensate managed via standard drainage. Features advanced multi-stage filtration (F7 + G4) that captures pollen, fine dust, and allergens for cleaner indoor air. The Shutter + Preheating model differs from the base STD version by featuring an automatic damper that seals the ventilation duct when switched off—preventing cold air from entering—as well as an integrated preheating element to warm incoming outdoor air during extreme cold. 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). Sensible Heat Recovery: Counter-flow sensible heat exchanger recovers up to 91% of thermal energy, preventing heat loss while safely managing condensation during cold seasons. 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.
