Technical details and functionality
The NX Adconair is based on the proven Adconair technology and is characterised by the following technical features:
Housing made of corrosion-resistant materials to ensure a long service life.
Heat recovery via a polypropylene plate heat exchanger with particularly high resistance and efficiency.
Integrated free cooling, which can significantly reduce operating costs in summer.
Optimised fans with EC technology that enable quiet and energy-efficient operation.
Modular design that allows easy maintenance and adaptation to different building requirements.
How does counterflow heat recovery work?
How it works
Heat recovery is at the heart of the NX Adconair. But what exactly does that mean?
During ventilation, warm exhaust air flows out of the building, while cold fresh air is channelled into the building from outside. Normally, the heat would simply be lost. This is where counterflow technology comes into play:
Efficient heat exchange: the warm extract air and the cold supply air flow past each other in opposite directions through separate ducts. The heat is thus transferred to the fresh air - without the air flows mixing.
Over 80 % heat recovery: Thanks to this clever technology, a large proportion of the heat is retained so that less heating is required in winter and less cooling in summer. This saves energy and reduces costs.
Minimal pressure loss: Heat exchange takes place with a pressure loss of just 115 Pa. This means that the fans have to work less, which reduces power consumption.
Environmentally friendly cleaning: The plate heat exchanger is made of polypropylene, a resistant material that can be cleaned with pure water - without any chemical additives that could pollute the waste water.

Further Adconair products for maximum efficiency
In addition to the NX Adconair, there are two other models based on this innovative heat recovery technology.
)
Adconair Adiabatic
This variant also utilises adiabatic cooling to regulate the room temperature even more efficiently. This can drastically reduce the cooling load in many applications.
)
Adconair Adiabatic ZeroGWP
A further development with a special focus on sustainability: this model works completely without climate-damaging refrigerants (Zero Global Warming Potential), making it one of the most environmentally friendly solutions on the market. Ideal for future-orientated buildings with high ecological standards.
Both variants combine proven counterflow heat recovery with innovative cooling technology to take energy efficiency and environmental friendliness to a new level.

Pressure tapping points for precise measurements and optimised airflow analyses
Our innovative solutions record the static pressure difference across the fan, record external pressure losses in the duct system and measure the pressure difference across the airways of the counterflow plate heat exchanger. In addition, our pressure tapping points provide accurate measurements of the differential pressures at the inlet nozzles as well as the static pressure differences of the filters.
The documentation of our pressure tapping points is a matter of course for us. Included in the scope of delivery is a precise measuring point drawing, which provides a transparent overview of our advanced systems. Rely on Menerga for innovative solutions and reliable pressure measurements in every application situation.
First-class air filtration to the highest standard
Our pocket filters for extract and outdoor air belong to the high-performance class ISO ePM10 60 %, while our supply air filters are compact filters of the ISO ePM1 55 % quality class. With self-sealing rubber lips, they provide reliable sealing against leckage air.
Monitoring of filter pressure losses is carried out precisely by our built-in pressure transmitters. Another highlight: our filters are fully incinerable, which not only facilitates disposal but is also environmentally friendly. Rely on Menerga for high-quality air filtration and first-class filter technologies that ensure efficient protection and clean air in every application
Efficiency and optimal control with our heat recovery bypass solutions
Our recuperator units are equipped with 2 bypass dampers that allow flexible bypass of the heat recovery unit while ensuring an efficient defrost function. The heat recovery bypass is effective over the full unit depth, resulting in minimal pressure losses during operation.
The advanced heat recovery bypass systems not only provide maximum efficiency, but also precise control over the heat transfer process. They allow tailoring to the specific requirements of your building air conditioning while ensuring energy-efficient use.
Discover the future of heat recovery technology with Menerga's heat recovery bypass solutions - for tailored efficiency and maximum performance.
Recuperator units with state-of-the-art counterflow plate heat exchangers
Equipped with innovative counterflow polypropylene plate heat exchangers. With a minimum counterflow rate of 80 %, our heat exchangers have been specially optimised for the requirements of building air conditioning. They ensure optimum air flow at all operating points, high heat recovery coefficient and minimum flow losses as well as efficient condensate removal. Our integrated design ensures that the heat exchanger is fully effective over the entire unit depth and provides optimum efficiency over the entire outdoor temperature range.

They meet the highest cleaning standards according to VDI 6022 and are fully cleanable. The base plate in the recuperator section functions as a condensate tray with drain and water seal, while the polypropylene material complies with building material class B2 according to DIN 4102-1 and has been tested by the Materials Testing Authority (MPA). Discover the future of energy-efficient building air conditioning with Menerga's recuperator units - for sustainable performance and first-class quality.
Air flow control
This innovative solution enables load-dependent volume flow control by means of a precise pressure measuring device in the inlet nozzle of the fan impeller and a static pressure tapping point in the fan intake chamber. The pressure is recorded via an integrated pressure transmitter in the unit, while the volume flow is determined by precise differential pressure measurement and evaluated by the controller.
Our volumetric flow device is programmed at the factory via DDC control to ensure optimum performance and efficiency. With this advanced technology, you have full control over the airflow in your premises. Trust Menerga for innovative solutions that meet your requirements for precision and efficiency.
