Aria Evo

aria evo sq

Valsir’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.

Aria Evo V

  • 5 models with flow rates of 150 and 600 m3/h.
  • Polypropylene foam casing for improved thermal and acoustic insulation.
  • Vertical floor or wall-mounted installation.
  • Automatic by-pass as standard.
  • Remote controls and probes with radio frequency communication.
  • Plug & Play system.
  • Left or right configuration installation.

Sanif-ox improves air quality

  • Sanif-ox reduces the occurrence of airborne viral and bacterial diseases and the causes of many allergies.
  • Thanks to the oxidising power of Sanif-ox, moulds, spores, fungi and pollen are inactivated, improving room comfort.
  • The oxygen molecules activated by Sanif-ox attack odours by breaking down the substances that cause them into simple compounds.

Idronica, Isoterma e Maxima

idronica isoterma maxima

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.

Air handling units: Idronica, Isoterma e Maxima

  • Fans with low consumption EC motor.
  • Very high-efficiency heat recovery unit (up to 90%).
  • 20 mm thick sandwich panel support structure with sound-absorbing and heat-insulating insulation.
  • Filters of class ISO Coarse ≥65% (former G4)
  • Air dehumidification via recirculation circuit with compressor (Maxima and Isoterma) or hydronic coil (Idronica).
  • Heat integration in both hot and cold mode (Maxima and Idronica).
  • Interface with building automation management system.
  • Possibility of independent management of the unit and the radiant system with control of the mixing valve, dew point alarm, opening and closing of the radiant areas (through additional thermostats for each area).
  • Horizontal ceiling installation or vertical wall installation.

Combination with radiating system

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.
