Outer fan casing manufactured from powder coated galvanised sheet steel providing long lasting and robust construction. The unit is finished in white RAL 9010. Internal structure manufactured from EPP (expanded polypropylene) providing reduced sound emissions and maximised air tightness and thermal insulation. Horizontal single row air supply grille with individually adjustable blades, made from anodised aluminum, with 20mm pitch. Extract perforated grille, integrated in the external steel casing. EC external rotor motors fitted as standard for energy saving. Provided with integral thermal protection, mounted on sealed for life ball bearings. Backward curved centrifugal impeller dynamically balanced and directly driven by the motor to provide a smooth airflow through the unit. Enthalpic heat exchanger with high thermal and latent efficiency. Made of antimicrobial technology, the built-in polymer membrane is mould and bacteria resistant: it also prevents the air flows contamination and block the odours. The special configuration generates low pressure drop. Very easy to be cleaned. Average efficiency: 85% thermal; 65% humidity. Ease of installation and cost saving: no air distribution system is needed. Simplified electric wiring: the unit is supplied pre-cabled. Enthalpic heat exchanger suitable to transfer thermal energy and humidity from one airflow to the other, keeping the correct indoor humidity level (4060%). During winter time, for example, it prevents that indoor air becomes too dry: in summer, instead, the humidity of the outdoor warm air is not transferred to the indoor cool air. ISO Coarse 60% filter (G4) supplied as standard. ISO ePM1 65% filter (F7) on request. Integral automatic bypass for free cooling during the summer season. Automatic anti-frost protection to prevent frost building up on the intake side of the heat exchanger. No condensation drainage is required. Tested to the latest standards: units are tested in the TUV Rheinland accredited internal laboratory at Aerauliqa according to the operating document IEC OD 2048 (level CTF1) for the IEC 60335-1 and IEC 60335-2-80 Standards, meaning accurate, up to date information on electrical safety, performance and noise level that can be relied upon. Designed and manufactured in accordance with EN60335-2-80 (Low Voltage Directive) and the EMC Directive (Electromagnetic Compatibility). The unit is supplied with a multi-function LCD display (CTRL-DSP) for automatic control and convenience, providing: • 3 speed settings (adjustable). • Boost option. • Holiday mode. • Night mode. • Weekly timer. • Bypass setting. • Airflow balancing. • Filter replacement and fan failure indicator. • Working hour counter. • Setting saving and loading. • Suitable for remote ambient sensors (SEN-HY, SEN-PIR). • Modbus interface. j-L RESIDENTIAL VENTILATION CATALOGUE

QR220DE Example of a complete ventilation system How it works: a continuous running decentralised heat recovery unit (QR220DE) transfers thermal energy and humidity from extracted humid air to warm incoming fresh air, with top acoustic comfort. No need of any condensation drainage or air distribution system.
