Aerauliqa QR280E Heat Exchanger with Humidity Recovery, up to 256 m³/h, filter
Central heating system with moisture recovery
The Enthalpy heat exchanger is suitable for transferring thermal energy and moisture from one air stream to another, while maintaining indoor humidity levels (40–60%). 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.
- Easy installation: A mounting bracket is included to make it easy to hang the device on the wall.
- Enthalpy heat exchanger.
- Simplified electrical connection: The device is supplied with a cord.
- An ISO coarse 60% (G4) filter that can be easily removed for cleaning. The unit can also be optionally equipped with an ISO ePM1 60% (F7) filter on the intake side.
- Integrated automatic bypass for cooling during the summer season.
- Automatic freeze protection to prevent freezing on the suction side of the heat exchanger.
- Two connections for condensate drainage make it easy to change the unit’s configuration and monitor condensate formation in both winter and summer.
- The device’s left/right configuration can be adjusted on the screen to ensure installation flexibility.
A central ventilation unit with heat recovery, suitable for vertical wall mounting.
Function
The fan’s outer housing is made of powder-coated galvanized steel for a durable and sturdy construction. The unit is white (RAL 9010).
The internal EPP (expanded polypropylene) structure reduces noise emissions and ensures maximum airtightness and thermal insulation.
Standard EC motors with external rotors for energy efficiency. Equipped with integrated thermal protection and mounted on sealed ball bearings for an extremely long service life.
A dynamically balanced, backward-curved centrifugal impeller, driven directly by a motor, ensures a smooth airflow through the unit.
An enthalpy heat exchanger suitable for transferring thermal energy and moisture from one air stream to another. It maintains the proper indoor humidity level (40–60%). 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.
