Disinfection tunnels, such as disinfection passages offered by Sani Pass, are a novel approach to the fight against COVID-19 spread. These solutions combine several technologies with proven effectiveness like full-body disinfection, hand sanitation, and mask detection.
Below is an infographic with brief overview of the disinfection passage use along with the highlights of its main benefits:
Now, look at the working principle of a disinfection tunnel and main advantages of its use in public places.
Disinfection of Public Spaces: What You Should Know
Disinfection is a procedure associated mostly with the healthcare setting. However, with the onset of the COVID-19 pandemic, it has become one of our main lines of defense against the virus. Public spaces are by far the most probable route for infection, both in terms of person-to-person contact and contraction from a contaminated surface. With social interaction playing such a vital role in our lives, this affects a range of public places where disinfection is necessary:
- Education: Schools, university campuses, colleges.
- Transportation: Airports, bus terminals, train stations.
- Retail: Supermarkets, malls, pharmacies.
- Hospitality: Hotels, restaurants.
- Entertainment: Concert venues, cinema theaters.
Now, there’s still no good data on how much of the infections account for each route of transmission. What is certain, though, is that the virus does survive on some objects for several days. In this light, disinfection along with other measures like respiratory etiquette are essential for the recovery from the current public health crisis.
How Does a Disinfection Tunnel Work?
The disinfection passage (disinfection tunnel) is a comprehensive sanitation and monitoring solution suitable for living organisms, goods, and raw materials. However, while the term “gateway disinfection tunnel” may sound overly technical, the technology behind it is actually quite straightforward. The sanitizer tunnel working principle can be broken down into three main aspects:
Let’s take a closer look at each of them.
Fogging: Safe and Efficient Disinfection Technology
The first part, disinfection, can be considered as the main line of defense. In most cases, this is done with a technology called fogging. Here’s how it works.
In its basic form, a disinfection tunnel consists of a metal frame with nozzles that disperse a sanitizing agent. Once a sensor detects someone entering the passageway, the nozzles start spreading the disinfectant atomized into tiny particles.
The particles form a dry fog and have low sedimentation speed, which allows permeating the surfaces of objects inside. At the same time, the fog does not leave any moisture, making it suitable for a broad range of applications.
Promoting Safe Behavior to Prevent the Spread
Disinfection alone is not enough to stop SARS-CoV-2 from spreading. To make a public place safe, we also need to make sure that everyone follows the rules of respiratory etiquette. And, while we mainly use tunnels to sanitize objects passing through them, they can also help cultivate these habits.
A full-body disinfection channel is equipped with three auxiliary security measures:
- Touchless hand sanitizer
- Smart mask recognition sensors
- Contactless body temperature measurement
Upon entry, the user’s face is scanned by an intelligent sensor. If no mask is detected or a temperature threshold is reached, the passage either starts an alarm or prevents the user from passing through. In a highly trafficked area, this small detail can improve public safety and develop good habits.
Seamless Monitoring and Analysis
Data analysis is a major part of the global response to the pandemic. Unfortunately, the data available is still scarce. Recognizing this, disinfection gate suppliers have added monitoring capabilities to their products.
The readings from the contactless temperature measurement system are collected and stored locally or uploaded to the cloud. This information will be useful for reporting and record-keeping purposes, which is why it is embraced as a part of school disinfection solutions. Besides, once processed, this data can reveal the ongoing trends or evaluate the organization’s safety measures, adding to the long-term safety.
Advantages of Disinfection Spraying Tunnels for COVID-19
Understanding how a disinfection tunnel works already gives a basic idea about its advantages. Effectiveness against pathogens is the factor that comes to mind first. However, from the organization’s standpoint, an intelligent disinfection station needs to be:
- Easy to install and operate
- Reliable and serviceable
- Fast and intuitive
- Integrated with data collection systems
Sani Pass has made every effort to tick all of the boxes above. Let’s look at each of these points in detail.
Comprehensive Thermometry and Disinfection Anti Epidemic Machine
Sanitizing the surfaces is the most apparent aspect of the anti-COVID measures. Yet it is only a part of the effort to battle the pandemic. Without changes in behaviors and attitudes, the disinfection tunnel has limited capacity. In order to promote healthy behaviors, our full-body disinfection channel is equipped with sensors that detect whether the user is wearing a mask. Depending on the setting, the tunnel can be configured to either encourage the user to wear PPE or prevent them from passing through.
Fully Contactless Operation
To complement the efficiency and thoroughness of the disinfection process, we’ve made sure that our full-body disinfection channel excludes every possibility of contamination. For this purpose, the entire procedure can be made without a single touchpoint. It includes temperature measurement, hand sanitation, and disinfection itself.

Safe and Efficient Disinfection Solution
Our full-body disinfection channel is effective against the SARS-CoV-2 virus as well as a broad range of other microorganisms while being completely safe for humans and other higher life forms. It was originally developed as a measure for ensuring the safety of large-scale public events, which posed several requirements such as convenience and reliability.
Therefore, we have settled on hypochlorous acid – a solution that has a number of useful properties, making it suitable for a variety of civil and industrial applications.
- Non-toxic: The disinfection gateway uses a completely harmless disinfection solution for human, animal, and plant life.
- Odorless and non-irritant: The solution does not have any unpleasant side effects.
- Chemically-selective: Works only against microorganisms like bacteria and viruses without affecting higher forms of life.
- Food-grade: Hypochlorous acid is approved for use in food service and water distribution.
- Zero-residue: The lack of visible traces makes it suitable for public applications.
- Environmentally friendly: The solution is biodegradable, occurs naturally, and does not accumulate in the organism.
As can be seen, the chosen disinfectant is not only safe and efficient but also convenient for application in non-specialized environments like public spaces and crowded events, educational amenities, hospitals, retail venues, public transport stations, hotels, and sports centers.
In certain scenarios, a disinfection tunnel is a stationary solution installed for continuous operation. However, there are also plenty of cases where it has to be installed temporarily, often within relatively short time frames. The Sani Pass line-up features several models of different sizes:
- Full-size disinfection passage
- Luggage disinfection unit
- Portable fogger
- Disinfection robot
All models are made from durable and lightweight materials and designed to simplify the assembly and installation. To further enhance security, we also offer standalone body temperature monitoring systems and hand sanitizers for situations where full-body disinfection is not necessary.
Tunnels are designed to operate in crowded environments and can accommodate heavy human traffic. The machine is also highly intuitive and distraction-free so that the entire operation can be accomplished within 10 seconds. It includes mask detection, hand sanitation, and full-body disinfection.
The disinfection procedure is powered by smart sensors and is highly autonomous, requiring no servicing on site aside from occasional disinfectant refill. Not only that, the data gathered during the disinfection process can be collected and analyzed to obtain valuable insights like customer or employee attendance. This data can then be used to adjust safety policies or for similar managerial decisions.
How to Use a Disinfection Passage
In a public setting, one of the main disinfection tunnel benefits is its ease of use for visitors. When you are in a hurry for an international flight, the last thing you’d want is to waste time on figuring out how a sanitizer tunnel works. Fortunately, interacting with a full-body disinfection channel is quite easy. From the user’s standpoint, it would look like this:
- Enter the disinfection gateway;
- Wait for a few seconds until fogging is complete;
- Step out of the unit on the other side.
Now, keep in mind that there are currently many variations of the disinfection tunnel solution, so there might be additional steps in the process. For example, you may need to wash your hands using a dispenser before entering or take your temperature measured with a contactless thermometer while you are inside. There are also units that can detect whether you are wearing a mask and deny entry access if you don’t. Still, the basic premise is the same: step in, wait for several seconds, step out.
The airline industry has already recognized its potential, so the sight of a disinfection tunnel in an airport is quite common. There’s even a possibility that the technology can become a mainstay in the airline industry even after the pandemic subsides.
Disinfection Tunnel FAQ
As the technology is still new, very little information about disinfection tunnels is available online. Below are some of the most relevant questions answered.
What is Disinfection?
Disinfection is one of the processes that eliminate pathogens from an object or environment. When it comes to the chemical composition of a disinfectant, other terms can be used. These refer to somewhat different procedures (e.g., sterilization is more specific, sanitation is more generalized).
Is a Disinfection Tunnel Effective Against COVID?
Our disinfection sanitizing tunnel uses a chemical solution that has been shown to eradicate pathogens that are harder to kill than SARS-CoV-2. Preliminary research also suggests that it is extremely efficient when applied through fogging.
Is Disinfection Tunnel Safe?
The concerns about whether a disinfection tunnel is safe or not stem from early models that used substances harmful to humans. Depending on their purpose, fogging machines can use different disinfectants:
- Hypochlorous acid
- Sodium hypochlorite
- Hydrogen peroxide
Most of these are hazardous substances and should not be used in a sanitizer tunnel for human applications. The Sani Pass disinfection passage uses a food-grade organic solution that is completely harmless to people but eradicates a broad spectrum of viruses and bacteria. It also leaves no trace on fabric, leather, and other surfaces, making it a viable solution for disinfecting personal possessions in public places.
Disinfection tunnels provide several layers of protection against COVID-19. These include physical disinfection of surfaces, detection of risky behaviors, and data collection and analysis. On top of that, they are highly autonomous, easy to deploy, and intuitive to operate. In combination, these advantages make them an efficient and non-intrusive solution for addressing the ongoing public health crisis.
