alvento LG-series - passive ventilation systems
Don´t lose valuable heat by ventilating.

With the LG series central air handling units, it is possible to recover a lot of heat without using a lot of energy.

Thanks to extremely efficient technology, the cross-counterflow heat exchangers installed in the passive ventilation units generate efficiencies of up to 95%. Such a heat exchanger consists of several plates, past which the two air streams flow on one side each. With the LG series, you can achieve a supply air temperature of about +15 °C compared to normal window ventilation at an outside temperature of -15 °C, which means that the heat requirement is reduced accordingly.


For faster installation, the system is factory-equipped with the following components:

  • Highly efficient cross-counterflow heat exchanger or enthalpy heat exchanger for controlled residential ventilation
  • Heat recovery efficiencies up to 95%
  • User-friendly touch panel (control panel) and integrated gateway
  • controllable via app
  • quiet operation
     

Additionally included in delivery:

  • Air connection spigot on the top of the unit 160 mm
  • summer bypass integrated in the unit
  • Touch panel (control panel)
  • Gateway
  • Integrated humidity sensor
  • EC centrifugal fans
  • G4 filter for exhaust air and F7 filter for supply air

With the central ventilation systems of the LG series, it is possible to recover a lot of heat without much energy input.

The built-in cross-countercurrent heat exchangers achieve efficiencies up to 96 %. Thes heat exchangers consist of several plates, where the air streams flow by. The LG-series reach a supply air temperature of about +15° C compared to a normal window ventilation with an outside temperature of -15° C, which means that the heat demand is reduced accordingly.

For faster installation, the system comes with the following components:

  • High efficients cross-countercurrent heat exchanger 
  • Integrated summer bypass flaps
  • User-friendly controller

 

Additionally delivery:

  • Air connection on the top of the device 160mm, including wall mounting
  • Controller
  • Moisture sensor
  • 4-stage EC radio fans for supply and exhaust air
  • G4-filter for exhaust air and F7-filter for supply air
