Automated Room Disinfection by Aerosol

Seamless 3D room disinfection in room hygiene

Ct-20 Hotel V2.0

Case Study: Aerosol Disinfection in Facility Maintenance

Group Guesthouse/Seminar Hotel, Switzerland: „We regularly rent out our guesthouse to groups. Unfortunately, we have encountered cases of norovirus. After an infected group departs, the house was manually cleaned and disinfected – without success. By acquiring a CT 20 aerosol device, we were able to eradicate the problematic germs room by room. Since then, we use the device whenever illness cases occur during an event.“

Automated Room Disinfection through an Airborne System in Facility Maintenance

Since the onset of the COVID-19 pandemic, awareness of targeted disinfection applications for hygiene optimization in facility maintenance has significantly increased. The possibility of whole-room disinfection in business areas, public services, cultural and educational sectors, and hospitality provides an ideal complement to traditional disinfection methods such as spraying and wiping. This is not only for mitigating COVID-19 risks but also for reducing the spread of „classic“ infectious diseases such as flu, respiratory infections, or gastroenteritis.

Aerosol disinfection effectively complements traditional surface disinfection in facility maintenance, helping to close hygiene gaps. In aerosol disinfection, disinfectants are sprayed into the air as fine particles, thoroughly disinfecting previously unreachable areas such as room air and hard-to-access surfaces. This method enables comprehensive decontamination of surfaces that might otherwise be overlooked.

Whole-Room Disinfection in Facility Maintenance: Frequently Asked Questions (FAQ)

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

A: No, that is not possible. While aerosol disinfection provides more comprehensive and better coverage of all surfaces compared to wipe disinfection, it has limited penetration depth. Even small dirt residues can significantly reduce the effectiveness of aHP disinfection, making thorough pre-cleaning indispensable. Aerosol technology is an additional safety measure for mitigating microbiological risks.

Q: Is aerosol disinfection suitable for quick interim disinfection?

A: No. Due to the time required for thorough 3D room disinfection, this technology is less suitable for quick interim disinfection. However, it is ideal for thorough base disinfection in conjunction with other hygiene measures.

Q: How long does a proper aerosol disinfection take?

A: The required time consists of A) the spraying time – the time it takes to nebulize a certain amount of disinfectant in a room, and B) the necessary exposure and decomposition time. During the exposure time, germs are actively reduced. Simultaneously, the hydrogen peroxide breaks down into water and oxygen. This process takes at least 120 minutes – overnight application is ideal.

Q: Can aerosol disinfection be performed in the presence of people (or animals)?

A: No, that is not possible. During and for some time after the disinfection, no persons or animals should be present in the treated room, and doors/windows must remain closed.

Q: Are electronic devices damaged by aerosol disinfection with boosted hydrogen peroxide?

A: Various independent studies and our own experiences show that electronic devices such as PCs, tablets, flat screens, mobile phones, etc., are not affected by aerosol disinfection with hydrogen peroxide. In contrast, chlorine dioxide or peracetic acid solutions can compromise the integrity of electronic devices.

Q: What are the advantages of Sanosil disinfectants with boosted hydrogen peroxide compared to other products used for this purpose?

A: Sanosil Q-Dis (and S015) are exceptionally suited for whole-room disinfection. They

  • pose fewer health risks and problems than vaporized formaldehyde,
  • are gentler on materials and less odorous than peracetic acid-hydrogen peroxide systems,
  • are easier to establish in cycles and safer to handle than H2O2 vapor systems (VpHP),
  • do not promote microbial resistance like QAV products,
  • have comprehensive tested efficacy (Standard EN 17272 / AFNOR NFT 72-281) – unlike most systems with anolyte, active chlorine, or hypochlorous acid.

Q: What are the different fogging technologies and devices used for room disinfection by aerosol?

A: Fogging devices basically use two technologies to generate aerosols: compressor & nozzle or turbine. A compressor presses the disinfectant through a nozzle to produce aerosols. With a turbine, on the other hand, the disinfectant is entrained by an air stream using the Venturi effect and finely atomized. Both technologies have their preferred areas of application. Compressor devices are more suitable for small and medium-sized rooms, while turbine devices are more suitable for medium-sized to large rooms.
(The Sanosil Q-Jet CT-20 has both technologies and can therefore be used for rooms with a volume of 4 – 600m³).

 

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 main purpose is to manually and directly spray surfaces with a fine mist. This inevitably creates aerosols, requiring appropriate personal protective equipment during disinfection. However, unlike aerosol disinfection devices, the majority of the sprayed disinfectant from spray mist devices lands directly on the treated surfaces due to the directed spray direction. These surfaces typically become moistened.

Aerosol devices, on the other hand, generate a „dry“ mist that evenly disperses throughout the room. This method avoids the moistening of surfaces.
