HEAT RECUPERATORS WITH AIR-AIR CROSS FLOW OVERVIEW AND CONSTRUCTION DETAILS OVERVIEW : The XRC series of heat recuperators are fitted with a highly efficient air-air heat exchanger that makes it possible to reuse a significant amount of the heat present in the extracted air. It is therefore suitable for all those installations where a significant amount of heat can be recovered thereby making energy savings, such as in ventilation systems in shops, offices, catering premises, bars and restaurants. CONSTRUCTION DETAILS: - The XRC model is made with an aluminium profile structure and box shape panels of prevarnished galvanized steel, internally isolated with glass wool having an average thickness of 15 mm, ideal to guarantee the maximum results for acoustic and thermal isolation with density greater than than 120 Kg/m³. - Static type heat exchanger, highly efficient, made with aluminium plates using cross-air flows kept separate by a suitable sealing. - G4 class supply and extraction filter elements, wavy model, in polyester fibre with a metal frame and electrically welded containment net with purposely ideated slots to facilitate maintenance and periodic substitution. - Supply and extraction centrifugal ventilators with double aspiration removable on each side of the unit for frequent maintenance. - One or three speed electric motors directly coupled, usually available in stock 1 speed version. - On board terminal for electrical connections and ventilators control.

HEAT RECUPERATORS WITH AIR-AIR CROSS FLOW COOLING SECTION : Allows cooling and the possibility of dehumidifying the air on exit from the recuperator unit. An exchange battery is used with copper tubing and and aluminium pack with a collection basin in galvanized steel. The unit is boxed in a special aluminium profile casing and a dobble panel, sandwich, system insulated with glass wool. The characteristics of the frame allow the unit to be fixed into place in linear square air ducts. Example of connection between recuperator and battery unit. Duct connectors are not supplied.
