Metro and railroad stations

Railroad stations are still the most important traffic nodes in some towns and cities. Numerous human beings move daily in them and make them attractive locations.

The air conditioning of these highly frequented and centrally situated building complexes poses very special challenges to building services engineering. The central location and the high level of diversity in the usage with restaurants, takeaways, sales areas, hotels, smoking zones, supply and disposal or hospitals bring corresponding pollutant sources and, in general, poor quality of air with them. The demands for good air quality are comparable with the challenges for airports, restaurants or even hospitals.

ionair AQS helps in the optimal design of the ventilation concept and ensures high efficiency in operation and a high level of quality for the competing forms of usage.

Briefly and concisely explained
There’s no question about it: we need it. Fresh air to live that is. However, the quality of our indoor air is not always particularly good. Industry, traffic or other sources of emission blow out harmful substances, which means that ventilation and air conditioning in buildings is a real challenge. Ionization provides a remedy. We explain here in a straightforward and comprehensible way how this works. We hope you find it interesting…


Ionization removes viruses
The results surpassed all our expectations. The test arrangement demonstrated that a reduction in surrogate viruses of more than, believe it or not, 99 percent is possible thanks to ionization. You can see how the Air Quality System (AQS) from ionair accomplishes this in the video here…
