These units allow to extract a certain amount of exhaust air from the room and supply an equivalent quantity of fresh air.A crossflow aluminium plate exchanger assures an efficient heat exchange between exhaust and fresh air: therefore the fresh air is pre-heated or pre-cooled according to the seasons. The supply air is filtered before entering the heat recovery exchanger that is protected with a synthetic filter also at the exhaust air side.The supply air can optionally be re-heated with a hot water coil or with an electric coil.7 sizes are available: UR E : same as standard versions and equip-ped with electric heating coil with aluminium fins and double safety thermostatՕDouble suction centrifugal fans coupleddirectly to the electric motors, equipped with adjustable speeds via an electronic control tovary the flow rateG3 class synthetic filter on the air outlet ՕAluminium plate reheater housed in the con-densate tray that is easily removed from the bottomG3 class synthetic filter on the fresh air intake ՕSelf-bearing panels made of galvanized platewith injected polyurethane insulation and thickness 20 mm.Galvanized condensate tray ՕFans can be inspected from the bottomFilters can be removed from the bottom forcleaning or replacementՕTwo versions available for horizontal andvertical installation (it is not possible to install the cooling coil accessories and silencers for the vertical installation)Electronic Regulator with Slave Applicationallowing continuous variation of rotation speed and air flow rate > UR : standard version UR W : same as standard version and equip-ped with water heating coil with copper tubes and 3 rows aluminium fins.
