High-efficiency motors with the latest ec-technology in combination with flow-mechanically revised and specially balanced fans have almost eliminated the well-known air noise. ...
With a converted power consumption of only 0.09 W/m³/h, the e² is unsurpassed in energy efficiency, thus making an active contribution to environmental protection and saving money. The requirements of the current DIN 1946-6 for devices of efficiency class E are undercut by a multiple, which clearly underlines the world class of the device.
The e² works according to the well-known principle of regenerative heat exchange, which has been almost perfected by LUNOS. The so-called acuvent storage stone is located in the middle of the air flow of an ec motor with axial fan. By means of a reversing air flow, which is created by a targeted change in direction of the fan, the ceramic material is charged with the heat energy of the room air and releases it again to the outside air supplied. This happens so efficiently that only 10 % of the heating energy is lost through the ventilation. For a balanced supply and exhaust air balance, at least two or an even number of e² should be used. Equally important are efficient filters. Allergy sufferers can breathe a sigh of relief; with the optional pollen filter, pollen, dirt and suspended particles can no longer enter the home.
