The Nexxt: With heat recovery

For the highest hygiene standards

Heat recovery unit

The Nexxt is a heat recovery unit which, due to its high volume flow, is ideally suited for use in kindergartens, schools, offices, hotels, doctors' surgeries, but also for flats and houses.

Special features

Due to its very low power requirements, the Nexxt is very energy-efficient and enables low power consumption. The integrated control system ensures perfect interaction between the various components. Equipped with humidity-temperature sensors, the automatic control system ensures efficient ventilation with humidity protection even in the standard version. Optionally, the Nexxt can be equipped with the FM-EO wireless module for control and communication with other LUNOS components and for Smart Home integration.

The enthalpy heat exchanger achieves a heat recovery efficiency up to 84%. In addition, the mode of operation of the heat exchanger ensures largely ice-free operation and comfort in the interior even with cold outside air.

For the highest demands on hygiene: filters up to filter class F9 or epm1 80%.


Install the ventilation unit with a recommended minimum lateral clearance of 30 cm and a recommended minimum upward and downward clearance of 15 cm. The lateral distance is to ensure the ventilation function, the distance upwards and downwards is for mounting clearance. We recommend installing the unit at a height of 1.50 m to ensure user-friendly operation.


The diagnostic software from LUNOS can be connected to the Nexxt. You can read about the advantages of this here.

Optional electric damper lock: Opens or closes the wall duct automatically when the unit is switched on or off.
