Heat recovery units

Recuperatori di calore ad altissima efficienza

Highly efficient heat recovery units

The Valsir HRV Aria system provides a wide range of highly efficient dual flow heat recovery units for all types of installations.

The Aria range is composed of two models in different sizes that can be installed in the ceiling or on the wall and four models in different sizes that can be installed on the floor with higher air attachment for surface areas from 40 m² to 250 m² (suitable for apartments, villas and small commercial spaces).

All the Aria units are equipped with a bypass for free cooling in summer months and remote panel with multifunction control.

The available accessories are: electrical heating elements and water coils for pre and post heating, moisture probes, VOC probes and probes for CO2 for the control and dilution of pollutants.

Furthermore, all the Aria units can be fitted with an additional filter in class F7, (in addition to the standard G4 filter) to further improve the purity of the air introduced.
The Aria distribution system is easily and rapidly installed and is composed of articles that are suitable for all systems.
