AERAULIQUA QR550 Heat recovery unit

APPLICATION

Whole-house heat recovery unit, suitable for vertical mounting.

SPECIFICATION

Outer fan casing manufactured from powder coated galvanised sheet steel providing long lasting and robust construction.

The unit is finished in white RAL 9010. Internal structure manufactured from EPP (expanded polypropylene) providing reduced sound emissions and maximised air tightness and thermal insulation. EC external rotor motors fitted as standard for energy saving. Provided with integral thermal protection, mounted on sealed for life ball bearings. Backward curved centrifugal impeller dynamically balanced and directly driven by the motor to provide a smooth airflow. through the unit. Highly efficient counter flow heat exchanger to maximise thermal recovery. Thermal efficiency of the heat exchanger up to 90% (test method in conformity with the norm EN308).

FEATURES & BENEFITS

Ease of installation: fixing bracket supplied to hang the unit easily on the wall. Heat exchange of the unit up to 92% efficiency.

Front panel easy removable for access to filters and heat exchanger. G4 filters easy removable for cleaning. The unit is also provided with an F7 filter at the intake side. Integrated bypass for free cooling; manual on the MBP model, automatic on the ABP version. Automatic anti-frost protection to prevent frost building up on the intake side of the heat exchanger. Two drainage holes to meet climate requirement. Tested to the latest standards: units are tested in the TÜV Rheinland recognised laboratory at Aerauliqa, meaning accurate, up to date information on electrical safety, performance and noise level that can be relied upon. Thermal efficiency and SFP (Specific Fan Power) measured at BRE independent laboratory (UK).

CONTROL

The unit supplied with a multi-function LCD display (CTRL-DSP) for automatic control and convenience, providing:
• 3 speeds setting
• Boost option
• Holiday mode
• Night mode: during night time the automatic operation via sensors is deactivated to prevent undesired speed rise and consequent noise increase.
• Automatic Bypass.
• Airflow balancing.
• Filter replacement and fan failure indicator.
• Woking hour counter
• Setting saving and loading.
• Volt-free contacts for remote ambient sensors (SEN-HY, SEN-PIR, SEN-CO2). Analogic input 1-10V for “slave” function if connected to BMS (home automation) system. Integral S/L terminal for boost from remote switch, i.e. light or dedicated switch. Connection to remote pre/post heating element. Connection to remote dehumidifying element.
