The HR UA series of mechanical ventilation units with heat recovery are machines designed to treat large volumes of air. Available in a wide range of capacities and configurations, they meet the needs for air exchange in tertiary buildings of different types and sizes.

The units are constructed with self-supporting sandwich panels made of 40 mm thick pre-painted sheet metal with rock wool thermo-acoustic insulation. They are equipped with a polypropylene countercurrent heat recovery unit with > 90% efficiency and are fitted with EC-type centrifugal fans with backward inclined blades.
