Exhaust air: ego with heat recovery
High efficient motors, with the latest ec technology combined with specially balanced fans which have been reworked with regard to fluid mechanics have almost completely eliminated any air noise. This has resulted in low measuring surface sound pressure levels.
The ego has a very low power consumption ensuring it is unique in terms of energy efficiency, making an active contribution to environmental protection and at the same time saving you money. The efficiency figures are far below the limits required pursuant to the current DIN 1946-6 for devices of efficiency class E.
ego operates in accordance with the well-known principle of the regenerative heat exchanger which has been almost perfected by LUNOS. The so-called acuvent storage stone is located at the center of the airflow of an ec-motor with axial fan. By means of a reversing airflow arising via systematic change of direction of the fan, the ceramic is charged with the thermal energy of the room air and transfers this back to the outside air supplied.
e2 and ego are among the smallest de-centralized fans for domestic ventilation with heat recovery in the world. By applying state of the art production processes we have managed to develop compact heat storage of ceramic composite material which provides a mean thermal efficiency up to 99.5% or 87.7%.
If a LUNOS ventilation system has already been installed, an ego can be used in existing outside wall air outlets.
egocan be used in new constructions and in redevelopment work. In new constructions, they are installed between the bricks with the aid of a wall rack or installed subsequently e.g. in the case of redevelopment work using a 162 mm large core drill hole. The wall must be at least 30 cm thick.
