The Lunos Nexxt is a decentralized HRV unit achieving a heat recovery rate of up to 90%. It is specially designed for larger spaces, not only homes but commercial spaces such as schools, offices, hotels and hospitals.

Heat transfer is made via a cross-flow heat exchanger or optionally via a cross-counterflow heat exchanger. Power input commences as of 5 Watts and volume flows of over 90 m³/h can be generated.

As standard, the Nexxt introduces a new operating concept: controlled via humidity or temperature sensors.

Advantages

• Low noise level thanks to ec technology

The radial ec motors of the Nexxt are convincing all along the line. Nestled in a flow-optimised EPP chassis, the ec motors, which are already very quiet, are virtually "silenced". Thereby, the Nexxt is currently one of the quietest units in its class.

The intelligent design achieves a standard sound level difference of 54 dB, making the Nexxt even suitable for use in the vicinity of airports.

• Efficiency

Thanks to its very low power consumption, the Nexxt is very energy-efficient, thus making an active contribution to environmental protection. The highly efficient ec technology enables low power consumption.

• Heat recovery & control technology

The key component of the Nexxt is the built-in device with heat exchanger:

NXT-E: The enthalpy heat exchanger achieves heat recovery levels of up to 85 %. 73 % according to EN 13141-8 at 75 m³/h (reference volume flow).

The integrated control provides for perfect interaction. Equipped with humidity-temperature sensors, even the standard version of the automatic control ensures efficient ventilation with humidity protection. Optional sensors such as, for example, the CO2 sensor can be integrated or connected by the EnOcean wireless technology.

• LUNOS Design Line

The Nexxt adds the waveform to the current design language of LUNOS products while maintaining its basic principles and recognition value. With an inner screen size of 510 x 510 mm, the fan thus remains a stylish element of home technology. The front screen also contains the plainly designed control panel. The total depth of 240 mm can be lowered up to 67 mm into the outer wall.

• LUNOS Compatibility

By using the 160 LUNOS standard wall-tube as wall duct, the Nexxt is compatible with the fans of the 160 series. Only for the outer covering a two-way outer screen or outer hood must be used. In the surface-mounted version, it is particularly easy to replace a 160 fan by the Nexxt.

• The Nexxt - housings can be used universally

Developed for the outer wall, the fan can be installed in the surface-mounted or flush-mounted version. The flush-mounted version requires a wall thickness of at least 240 mm and the installation housing has a stylish design frame which makes it also visually appealing. The 160 wall-tube is used for the outside passage.
