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

- Energy efficiency class: A
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
