Indoor air disinfection in local transport
Air circulation in buses and trains
In general, ventilation and air conditioning in local transport, such as buses and trains, are centrally controlled. This also means that, apart from the Alass nozzles on the seats, all air currents are predetermined. As a rule, passengers have no direct influence on this. If the driver or sensors change these ventilation or air conditioning settings, this has a direct influence on all passengers. this is exactly where one of the central problems lies, comparable to integrated cooling systems in buildings. In the case of infected persons on board, pathogenic agents, here aerosols, are distributed to practically all passengers using a central control system. The same problem is understood when disinfection modules, regardless of the technology, are simply retrofitted in existing ventilation systems in buses and trains, even if this initially seems to be a sensible option.
Much better protection against infectious pathogens can be achieved with modules in which the ventilation and air conditioning system as well as the room air disinfection have separate circuits. This protection can be optimized even further by dividing this second air circuit over the passenger area again and thus creating separate laminar air circuits that cannot mix directly during the journey.The more clearly these circuits are separated, the better the protection. So it would be ideal to be able to mix the infectious air directly. The more clearly these cycles are separated, the better the protection. It would therefore be ideal to attack and eliminate the infectious air directly in the passenger.

Chemical-free disinfection of indoor air in stadiums, arenas, sports facilities
An amount for infection protection with certified UV-C technology from Martin Sembach, Director Strategic Business Development at GoGaS Goch GmbH & Co. KG.
In addition to the sporting events themselves, safety, reliability and comfort are among the basic needs and expectations of stadium visitors around the world. In 2020, the term security and the associated challenges posed by SARS CoV-2 became even more important. In its September 2, 2020 edition, the Ärzteblatt reported on how a so-called super spreader event came about in a tour group in Hangzhou, China, at the beginning of 2020. The group was split into two buses. According to Ärzteblatt, about 35% of the travelers were infected in the first bus during a 50-minute journey, not a single passenger in the second bus. The first time the air conditioning was out of order.
According to the findings of an investigation and study by JAMA Intern Med. 2020; 180 (12), the prevalence in the first bus is precisely due to this shortcoming. This post shows, based on this experience, that
Incidentally, it can be easily transferred to practically all rooms in stadiums, arenas and sports facilities with a large number of people, possibilities for better protection of visitors and staff, through the use of validated
Techniques for indoor air disinfection. The UV-C technology, which has been used successfully for more than 100 years in the medical, food, pharmaceutical and electrical industries, is used.
CONCLUSIONS FOR 2020
Easy Engineering: How was this year in terms of turnover?
Martin Sembach: 2020 was a year with challenges and opportunities. Looking at GoGaS business, being built around sustainability, energy efficiency and safety, our opportunities where much bigger than the challenges. One major reason for this
has been SARS-CoV-2 and its impact to all business around the globe. This global pandemic challenge has basically split the market into two segments. Companies whose business model had already been challenged before and companies who
took the challenge and did benefit from the fact, that SARS-CoV-2 gave them a strategic advantage in the markets they served.
Our company has clearly been on the winner side, allowing us to benefit from our clear strategy, serving all our customers with the most sustainable, energy efficient and total lowest cost solutions, in all the fields we served.
