alvento LG-series – passive ventilation systems

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
