Ariosa HV is the latest frontier of Valsir’s HRV units.
The unit is intended for residential applications and can be installed horizontally (in a false ceiling) or vertically (anchored to a wall).
Discover moreValsir’s Aria Evo HRV system offers a wide range of high-efficiency double flow heat recovery units for all types of installation.
The Aria Evo range consists of two models, with different flow rates, that can be installed in false ceilings or on walls, and five models of different sizes that can be installed on the floor, with upper air connections for surfaces from 40 m2 to 450 m2 (suitable for flats, villas and small businesses).
All Aria Evo units are equipped with by-pass for automatic summer free cooling and remote panel with multifunctional control.
All Aria Evo units allow the use of ePM10 (former G4) filters or ePM1 (former F7) fine mesh filters to further improve the purity of the supplied air.

The HRV system with dehumidification consists of a range of three models equipped with very high-efficiency dual-flow heat recovery units, for horizontal or vertical installation.
All the units are available in versions with internal cooling circuit (with cooling integration or only isothermal dehumidification) or with water coil, and are equipped with remote panel with multifunctional control.
The main accessories include: humidity probes, VOC probes and CO2 probes for monitoring and diluting pollutants. Possibility of operating in HRV only mode or HRV mode with dehumidification with partial recirculation.
Fresh air flow rate from 80 to 260 m3/h.
Total handled air flow rate from 260 to 520 m3/h.
Dehumidification from 27 to 63 l/h (up to 84 l/h for the Idronica version).
The advanced electronic components also allow the joint management of the mechanical ventilation system and radiant heating/cooling.

In the construction of new buildings the combination of a radiant system and a heat recovery ventilation system is increasingly requested. This is because the systems integrate perfectly in buildings with high energy performance. On the one hand, they provide heat recovery from the air exchanged with the outside and on the other hand, they optimise consumption thanks to the possibility of supplying the radiant system with water at lower temperatures than other heating systems, thus optimising the efficiency of heat pumps or boilers of the latest generation.
