Automated room disinfection in personnel transport vehicles using aerosol technology

Comprehensive Disinfection for Vehicles, Aircrafts, Railways, and Ships

Case Study: Aerosol Disinfection in Transportation

Public Transport Operation, Spain: „During the COVID-19 pandemic, we needed to protect our public transport passengers as much as possible from virus transmission. Firstly, we wiped down high-touch surfaces in our trams daily with disinfectant wipes. Secondly, we regularly treated the trams with aerosol disinfection. We could transport the aerosol devices (protected by a mask from the aerosols) directly to the next vehicle immediately after spraying. This allowed us to disinfect many vehicles quickly.“

Automated room disinfection in transportation vehicles using airborne disinfection systems

Routine disinfection of transportation vehicles is not typically practiced under normal circumstances. However, the issue becomes highly relevant when containing contagious diseases. According to CDC reports over the past 20 years, this has been notably relevant in instances such as:

COVID-19 pandemic (2019-2022)
Ebola outbreaks (various outbreaks between 2000 and 2021)
H1N1 influenza pandemic (swine flu, 2009)
H5N1 influenza pandemic (avian flu, 2015)

SARS outbreak (2002-2003)
MERS outbreaks (since 2012)
Norovirus (ongoing – various local outbreaks, especially on cruise ships)

The challenge arises when a large number of transportation vehicles need to be disinfected with limited personnel resources. Automated aerosol disinfection proves to be an extremely efficient method for disinfecting transport vehicles such as buses, subways/trains, and ships.

As an effective complement to traditional surface disinfection of critical touchpoints, it helps to quickly address hygiene gaps (such as air quality) with minimal personnel effort. Aerosol disinfection involves spraying disinfectants in the form of fine particles into the air to thoroughly disinfect hard-to-reach areas such as room air and inaccessible surfaces. This method enables comprehensive disinfection of surfaces that might otherwise be overlooked.

Whole-Room Disinfection in Transportation Vehicles: Frequently Asked Questions (FAQ)

Q: Can aerosol disinfection replace traditional cleaning or manual spray-wipe disinfection?

A: No, that’s not possible. While aerosol disinfection provides comprehensive coverage of all surfaces compared to wipe disinfection, it has limited penetration depth. Even small amounts of dirt residue significantly reduce the effectiveness of aHP disinfection, which is why thorough pre-cleaning cannot be skipped.
Aerosol technology serves as an additional safety measure to mitigate microbiological risks.

Q: What is the difference between a spray mist device and an aerosol device for automated room disinfection?

A: Portable spray devices are not classified as traditional aerosol devices. Their primary purpose is to manually and directly spray surfaces with a fine mist of disinfectant. This process inevitably creates aerosols, necessitating the use of appropriate personal protective equipment during disinfection. However, unlike aerosol disinfection devices, the majority of the sprayed disinfectant lands directly on the targeted surfaces due to the directed spray pattern. These surfaces typically become moistened.

In contrast, aerosol devices generate a „dry“ mist that evenly disperses throughout the room. This method avoids wetting surfaces with the disinfectant solution.

Q: What are the different aerosolization technologies and devices used for room disinfection via aerosol?

A: Aerosolization devices generally utilize two technologies to create aerosols: compressor & nozzle or turbine. A compressor pushes the disinfectant through a nozzle to generate aerosols. In contrast, a turbine entrains the disinfectant into an airflow using the Venturi effect, finely atomizing it. Both technologies have their preferred applications. Compressor devices are more suitable for small to medium-sized rooms, while turbine devices are more appropriate for medium to large rooms.

(The Sanosil Q-Jet C10 incorporates both technologies and can therefore be used for rooms ranging from 4 to 600 cubic meters in volume.)

Core Competencies

Our core competencies include the manufacturing and application consulting of disinfection products for water systems, surfaces, and air (complete room disinfection).

Water Disinfection

Sanosil disinfectants, through the use of specially stabilized and efficacy-enhanced hydrogen peroxide, are among the most effective products in this field

Surface Disinfection

Sanosil disinfectants do not contain large quantities of dissolved solids.
Therefore, they do not leave sticky surfaces even after repeated use

Auto. Room Disinfection

Automated 3-dimensional aerosol room disinfection closes the efficacy gaps of manual spray-wipe disinfection and optimizes its effectiveness
