Touring coach: fresh air every two minutes – much more regularly than at home and in the office

Numerous passengers on-board a touring coach – the fear that there is a greater risk of infection is an obvious one. But it's actually far from reality as the standard technology of Mercedes-Benz and Setra coaches already serves to minimise the risk. The fully automatic air conditioning system continuously changes the air inside the vehicle. Ventilation via the footwell creates a gentle, vertical air flow that prevents turbulence. At common outside temperatures between 8 and 26 degrees Celsius, the climate control system uses the maximum level of fresh air (between 80 and 100 percent), and there is therefore a continual and complete change of the air inside the vehicle every two minutes. Both at low and high temperatures, climate control systems work in mixed-air mode. Here, the renewal of fresh air in the interior occurs every four minutes. By way of comparison: in living spaces, a renewal of air is only prescribed at the very least every two hours, and in offices that figure is only every hour at the least.

And Daimler Buses is even going one step further: upon request, the maximum fresh air content of the air conditioning systems in the popular Mercedes-Benz Tourismo, Setra ComfortClass 500, TopClass 500 and S 531 DT double-decker coach series can be increased by as much as 33 or 40 percent by additionally extending the outside temperature range for maximum fresh air supply upwards and downwards. For touring coach companies, this additional share of fresh air from the air conditioning system is an attractive option for demonstrably further reducing the risk of infection for drivers and passengers.

New: standard high-performance particle filter with anti-viral functionality

Filter systems with anti-viral functionality are today already used in the climate control systems of buses from Setra to effectively remove particles from the air. New active filters increase this effect even further: the multi-layer, progressively designed high-performance particle filters additionally feature an anti-viral functional layer. This serves to filter out the finest aerosols. Physical tests and microbiological analyses confirm this effect. The active filters are used for the roof-mounted climate control systems, for the air-recirculation filter and also for the front climate control box.

The active filters can be ordered for the current Mercedes-Benz Tourismo as well as for the Setra S 531 DT double-decker bus and the Setra ComfortClass 500 and TopClass 500 touring coaches, both for new vehicles and as a retrofit solution. Mercedes-Benz and Setra can even retrofit existing models with them. Appropriate active filters for the Mercedes-Benz Citaro regular-service urban bus will follow this year. Vehicles equipped with an active filter are also fitted with a sticker in the entrance area which is visible to passengers.
