AERAULIQA QR400A HEAT RECOVERY VENTILATION UNIT Made in Italy
- Easy installation: A mounting bracket is included to make it easy to hang the device on the wall.
- Simplified electrical connection: The device is supplied with a cord.
- An ISO 60% (G4) coarse filter that can be easily removed for cleaning. If desired, the unit can also be equipped with an additional ISO ePM1 60% (F7) filter on the intake side.
- Integrated automatic bypass (without heat recovery) 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.
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 a lifetime of service.
A dynamically balanced, backward-curved centrifugal impeller, driven directly by a motor, ensures a smooth airflow through the unit.
A highly efficient counterflow heat exchanger for maximizing heat recovery.
The device is equipped with a multifunctional LCD screen (CTRL-DSP) to ensure automatic control and convenience, and offers:
• 3 speeds (adjustable).
• Zoom option.
• Vacation mode.
• Night mode.
• Weekly timer.
• Passing setting.
• Airflow equalization.
• Filter replacement indicator and fan malfunction.
• Work hours counter.
