Nexxt - The new variety in decentralised ventilation
The Nexxt is extremely energy efficient thanks to its very low power consumption. The ec-technology with high efficiency enables low power consumption.
The integrated control ensures perfect interaction of the various components. Equipped with humidity-temperature sensors, the automatic control system ensures efficient ventilation with moisture protection even in the standard version. Optionally the Nexxt can be equipped with the FM-EO radio module for control and communication with other LUNOS components and for Smart Home integration. The heart of the Nexxt is the plug-in unit with heat exchanger, which is available in two versions:
The enthalpy heat exchanger achieves a heat recovery rate of up to 83 %. In addition, the mode of operation of the heat exchanger ensures that it is largely ice-free and provides comfort in the interior even with cold outside air.
The cost-efficient variant with cross-flow heat exchanger achieves a heat recovery rate of up to 80 %. Installation The Nexxt can be installed both under and on plaster. In the surface-mounted variant, the installation housing is given a stylish design frame and is therefore also visually impressive. The well-known 160 mm wall-tube is used for the external feed-through.
Optional: Electric flap closure
Opens or closes the wall duct automatically when the device is switched on or off.
