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.

The second generation NXT-2 sets new standards in energy efficiency and modern system integration. Thanks to advanced ec technology, it operates with particularly low power consumption. The integrated control electronics feature a mains filter that effectively reduces interference. The new USB-C connection also enables fast and secure data transfer.

Special features

Even in the basic configuration, the integrated humidity and temperature sensors are impressive. These ensure demand-based ventilation and optimum humidity protection. At the heart of the NXT-2 is the innovative insert with enthalpy heat exchanger. With advanced membrane technology, it achieves heat recovery of up to 96% and operates with virtually no icing. This not only saves energy, but also creates a pleasant indoor climate.

The NXT-2 also scores points for its versatility. It is compatible with both available Inner screens, allowing it to be flexibly adapted to different room concepts.

Optionally it is possible to expand the NXT-2 with the new WLAN module 5/WM. This module enables easy configuration and precise calibration. In addition, the EnOcean FM-EO radio module is also available separately, supporting intelligent communication with other LUNOS components and smart home integration.

Filters up to filter class F9 or ePM1 80% ensure the highest standards of hygiene.

Installation

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.

Extra

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.

Information on the technical data

Show technical data

1) Silvento V are fan inserts that still require a flush-mounted or surface-mounted housing.

2) Silvento KL are complete single-pipe fans that are clamped into pre-wall constructions. Silvento KL single-pipe fans fit into the flush-mounted housings of the LUNOS Skalar series.

3) The specified values are achieved at 20°C, 1013hPa and 1.2kg/m3 ambient air density and (unless otherwise specified) are achievable between free-blowing condition and 60 Pa disturbance pressure in accordance with DIN18017-3.

4) When designing the volume flows, please observe the pressure-volume flow characteristics provided by LUNOS and the specifications of the abZ (DIBt approval)

5) Sound power level: The sound power level indicates how "loud" a device is. The value is independent of the distance.

6) Volume flow rate of the ALD-SV with a straight arrangement of the sound attenuation elements.

7) Max. achievable WBG according to EN13141-8 with reference volume flow rate.

8) At 70 % of the maximum volume flow rate, in accordance with ErP Directive, EU Regulation 1254/2014.

9) According to LÜA (test specification) of the DIBt and EN13141-8 max. achievable exhaust air volume flow free-blowing at 20°C and 1013hPa ambient conditions and 1.2kg/m3 ambient air density.

a) According to LÜA (test specification) of the DIBt, see also proof of usability (abZ), when using the wall-mounted housing 9/MRD as insulation, without 9/MRD 2% deduction.

b) According to LÜA (test specification) of the DIBt, max. achievable value.

c) According to EN 13141-8 with reference volume flow, see also certificate of usability (abZ) of the DIBt.

d) According to LÜA (test specification) of the DIBt and EN13141-7 max. achievable exhaust air volume flow free-blowing at 20°C and 1013hPa ambient conditions and 1.2kg/m3 ambient air density.

e) According to EN 13141-7 at reference volume flow rate, see also proof of usability (abZ) of the DIBt.

f) Determined by the Passive House Institute (PHI), see PHI certificate.
