Adconair variants at a glance

Adconair
Efficient air treatment without compromise
Our all-in-one system integrates a counterflow plate heat exchanger and offers an air volume flow of 2,730 - 36,900 m³/h. The counterflow plate heat exchanger sets the highest standards in terms of energy efficiency with a genuine counterflow proportion of over 80 % and a pressure loss of just 115 Pa. In addition, the polypropylene material used enables the adiabatic cooling system to be operated exclusively with pure water without the addition of cleaning agents or wetting agents and therefore does not pollute the waste water.

Adconair Adiabatic
Maximum cooling capacity, minimum energy
This appliance also contains an important component: the counterflow plate heat exchanger, which cools the extract air adiabatically. This means that the outside air is cooled indirectly by the extract air without moisture being transferred from the extract air to the supply air. The high efficiency of the heat exchanger and the high counterflow proportion of > 80 % ensure effective cooling with a temperature difference of more than 14 K. This variant can be extended by an integrated compression refrigeration system, which is switched on at high outside temperatures to cool the supply air to the desired temperature.

Adconair Adiabaticᶻᵉʳᵒᴳᵂᴾ
Sustainable cooling at the highest level of innovation
The Adconair Adiabaticᶻᵉʳᵒᴳᵂᴾ version utilises innovative technologies: indirect, adiabatic evaporative cooling takes place in the first half of the heat exchanger, as described for the Adconair Adiabatic systems. The outside air is already largely pre-cooled.
Dew point cooling takes place in the second half of the heat exchanger. Part of the pre-cooled outside air is discharged after the heat exchanger as a process air flow. This is fed back into the heat exchanger using the counterflow principle and humidified again. This results in indirect evaporative cooling. In contrast to conventional systems, the minimum temperature is no longer dependent on the wet bulb temperature of the exhaust air, but on the dew point of the pre-cooled outside air.
The proportion of outside air is up to 50 % of the nominal volume flow and is continuously controlled to ensure a constant supply air temperature. This performance must already be taken into account in the planning phase.

Adconair AdiabaticDXcarbonfree - thermally driven
Environmentally friendly cooling, highest efficiency
This all-in-one system is specially designed for production facilities, food industry, canteens and exhibition halls, and integrates a counterflow plate heat exchanger. The key components of this system consist of two modules equipped with silica gel as adsorption material. The system produces chilled water by applying a closed adsorption process, which is used in a change-over coil to cool and dehumidify the supply air. Temperatures in the refrigeration circuit are low enough to cool the outside air from 32 °C to about 16 °C, in combination with indirect, adiabatic evaporative cooling. While one module produces cold water through this process, the second module is regenerated. Hot water (from 55 °C) is used for this, which leads to desorption of the saturated silica gel. Desorption takes place at least as fast as adsorption, so that sufficient cooling energy is always available. The special feature of this concept is that there are no mechanical moving parts in the vacuum and the noise level is extremely low and vibration-free compared to conventional compressors.

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

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.
