- Innovative – Heat Recovery
Lunos e² operates according to the known principle of regenerative heat exchange. The so-called AcuVent storage stone is located in the middle of the airflow of an electric motor with an axial fan. By a reversing airflow, which results for the targeted change of direction of the fan, the ceramics are charged with heat-energy that is offloaded into the room air and discharged again to the air added from outdoors. This is carried out so effectively that a mere 10 % of the heating energy is lost by the ventilation With the help of state-of-the-art manufacturing processes it has been possible to develop a compact heat exchanger from a ceramic composite material which supplies a thermal efficiency factor of approx. 90.6 %. The combination with highly efficient electric motors and intelligent control has made it possible for LUNOS to develop one of the most economical ventilators.
The e² is the smallest decentralised fans on the field of home ventilation with heat recovery. Like the e²neo, the 160 fans e² and e²short are extremely compact in their volume flow class.
- Compatibility with other devices
If a LUNOS ventilation system has already been installed, an existing fan of the 160 series can be replaced by the fans e² and e²short. This is possible by the use of the same wall duct. In a new building the LUNOS e² can also be combined with all LUNOtherm elements.
- Versatile installation option
In a new building, as well as in a renovated building, all fans of the LUNOS e² series can be used. The e² is either installed in a new building with the help of a wall recess casing position between the stones, or subsequently, e.g. when renovating with the help of a 162 mm large core bore.
