Our QR family is expanding again!

We are pleased to announce the launch of the new QR340A model, the new centralized heat recovery unit for horizontal installation, ceiling or false-ceiling mounting.

The unit reaches an airflow of 300 m3/h at 100 Pa and it is equipped with EC brushless motors with very low electrical consumption and silent operation.
This silence is also guaranteed by the internal structure made of expanded polypropylene whose technical characteristics allow maximum tightness and thermal insulation.

The outer fan casing is made of galvanized and pre-painted RAL 9010 sheet steel for a robust and long-lasting construction.

The high efficient counterflow heat exchanger is the heart of the product. Its high quality allows the unit recover the thermal energy (warm or cold) from the extracted indoor air and transfers it to the fresh air introduced from the outside.
The internal temperature sensors manage the automatic activation of the bypass, ideal for the “free cooling” operation during the summer season, and the anti-frost function, which prevents the formation of ice on the heat exchanger in the colder months.

The unit is designed to have two holes for condensation drainage to be used according to different climatic needs.

The ISO Coarse (G4) filter for the supply and intake air or the more efficient ePM1 (F7) filter (on request) work for the constant maintenance of indoor air quality by introducing fresh air, free of pollen and dust. The filters’ maintenance and replacement are indicated by a visual signal on the control panel.

As the other QR units, the QR340A is supplied pre-cabled (power and control wires) to facilitate installation operations: an additional output is provided in case of external ambient sensor connection.

Thanks to the CTRL-DSP control panel with LCD display, supplied as standard, the installer can remotely commission the system while the user can monitor the unit status.
Here are some of the main features of the unit:

–          Setting/Selecting the operating mode between Normal (3 speeds), Holiday and Night
–          Setting/Selecting the Boost Function
–          Weekly program
–          Bypass Management
–          Airflow balancing
–          Filter maintenance and fan failure indicator
–          Working hours counter
–          Setting for ModBus interface
–          Connection to remote water coil or pre/post heating element

The product is already available to be ordered.
