Aerauliqa QR590E Heat Exchanger with Humidity Recovery, up to 561 m\u00b3\/h, filter<\/h2>\n
\n

The Enthalpy heat exchanger is suitable for transferring thermal energy and moisture from one air stream to another, while maintaining indoor humidity levels (40\u201360%). In winter, for example, it prevents the indoor air from becoming too dry; in summer, however, it prevents warm, humid air from entering the indoor space. <\/h4>\n

    Function<\/h3>\n
    \n

    The fan’s outer housing is made of powder-coated galvanized steel for a durable and sturdy construction. The unit is white (RAL 9010). <\/p>\n

    The internal EPP (expanded polypropylene) structure reduces noise emissions and ensures maximum airtightness and thermal insulation.<\/p>\n

    Standard EC motors with external rotors for energy efficiency. Equipped with integrated thermal protection and mounted on sealed ball bearings for a lifetime of service. <\/p>\n

    A dynamically balanced, backward-curved centrifugal impeller, driven directly by a motor, ensures a smooth airflow through the unit.<\/p>\n

    An enthalpy heat exchanger suitable for transferring thermal energy and moisture from one air stream to another. It maintains the proper indoor humidity level (40\u201360%). For example, in the winter, it prevents the indoor air from becoming too dry, and in the summer, it prevents moisture from the warm outdoor air from transferring to the cool indoor air. <\/p>\n

    The device is equipped with a multifunctional LCD screen (CTRL-DSP) to ensure automatic control and convenience, and offers:<\/p>\n

    \u2022 3 speeds (adjustable).<\/p>\n

    \u2022 Zoom option.<\/p>\n

    \u2022 Vacation mode.<\/p>\n

    \u2022 Airflow equalization.<\/p>\n

    \u2022 Filter replacement indicator and fan malfunction.<\/p>\n

    \u2022 Work hours counter.<\/p>\n

    \u2022 Saving and loading settings.<\/p>\n

    \u2022 Compatible with outdoor sensors (SEN-HY, SEN-PIR).<\/p>\n

    \u2022 ModBus interface.<\/p>\n

    \u2022 Connection with remote preheating or post-heating.<\/p>\n

    \u2022 Connection to an external water supply for heating.<\/p>\n

    \u2022 Left or right version (air connection).<\/p>\n<\/div>\n
