KWL fan unit e²60 with heat recovery for living rooms (V = up to 60 m³/h)

The e2 models work on the principle of regenerative heat exchangers. The storage stone sits in the centre of the air flow of an EC axial fan. The plastic (PLA) is charged with thermal energy from the room air by a reversing air flow, which is created by a targeted change in direction of the fan, and releases it back into the incoming outside air. This happens so efficiently that up to 96% of the heat energy contained in the air is recovered. The combination of e² and ego ensures one hundred per cent ventilation and Deaerators with heat recovery throughout the house and is ideal for KFW houses.
