energy recoveryresidentialfor home

Decentralised energy recovery unit, ideal for ceiling installation in public places, such as schoolrooms, offices, shops, waiting rooms.… 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 builtin 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 (40- 60%).
