Nexos Intelligent Disinfection

Using the disinfecting power of UV light technology, you can program a cycle to sterilize individual rooms or entire offices during nonbusiness hours quickly and efficiently while there is no occupancy. Give employees and others the confidence of being in a healthy environment.

Maintain A Healthy Environment

Nexos Intelligent Disinfection provides the ultimate peace of mind and flexibility for your space in-between occupancy. Manually engage the UV disinfection cycle after meetings to sanitize conference rooms before being occupied by another group, in common areas when empty, and in short increments throughout the day to maintain a safe work environment.

Intelligent Safety Processes

Before initiating the UV disinfection process, Nexos determines all safety checks are met. During the occupancy scan, the Nexos Intelligent Disinfection software pulls data from occupancy sensors, people counting, and door locks to determine the space is unoccupied, ensuring the safety of your employees.

Automated UV Disinfection Cycle

Once a space is determined to be unoccupied during the safety checks, Nexos commands the UVC lighting and other sanitizing equipment in the space to initiate the disinfection process. When the process is activated, doors are triggered to lock from the outside and exterior signals indicate that disinfection is in progress. Nexos Intelligent Disinfection automatically starts and finishes the complete sanitization of your space while ensuring the safety of all occupants.

Intelligent UV Disinfection for Safer Buildings

Nexos Intelligent Disinfection connects with UVC lighting, sensors, access controls, and other hardware to create an automated process to disinfect spaces safely.

Real-World Applications

For the economy and life to return to normal, advanced and widespread disinfection processes are necessary. However, UVC lighting is harmful to people, so it must be paired with intelligent controls to allow for the safe UV disinfection of public spaces.

Corporate Offices and
Conference Rooms

Show your employees you care by installing UVC lighting with market-leading safety precautions in your most trafficked spaces. This, combined with other safety precautions such as reduced in-office staff, can allow you to bring employees back to collaborate and work together as safely as possible. The data from the software can show you insights on how often spaces are used, whether they are exceeding the number of people allowed per room, how often disinfections occurs, and more.

Senior Living

Protect our most vulnerable loved ones by installing UVC lighting with market-leading safety precautions in any senior living space. This should be added on top of your safety precautions to add another significant layer of protection against COVID-19, influenza, pneumonia, and other communicable outbreaks. The data from the software can show how often UVC disinfections occurs, pull data from heartbeat and temperature sensors to predict illness, and more.

Healthcare

Protect your patients and employees with safe UVC disinfection. UVC lighting sterilizes exposed spaces when used as directed, but it is dangerous to humans. Nexos software provides multiple layers of security measures that can create safe UVC lighting usage in existing spaces. The software-based controls are flexible and provide facilities the ability to see what is going on in their spaces and answer critical questions: How often are people in the space? Does it ever exceed occupancy limits? When does disinfection occur, and how often? Does the disinfection process get interrupted? This data allows hospitals to find and benefit from data-driven insights to decrease the spread of viruses and other diseases in the healthcare setting.

Education

Install UVC lighting with market-leading safety precautions in your most trafficked spaces and classrooms to prevent illness outbreaks. Run the UVC lighting overnight to fully disinfect all classrooms and spaces, and then use maintenance disinfection throughout the day when the spaces are unoccupied, such as when students are at recess, to continually sanitize spaces. Data generated from this solution can be combined with other sensor data for many insights. Use it to measure adherence to capacity limits as a way of enforcing your other measures of transmission prevention and to see how often disinfection occurs or is interrupted. Tell your students, staff, and parents about adding this disinfection layer to your current precautions to help ease concerns about returning to school.

Hospitality

Protect your guests and staff by installing UVC lighting with market-leading safety precautions in your most trafficked spaces and guest rooms. Share that you are adding this additional disinfection layer to your current cleaning procedures to restore your guests’ confidence in your brand. Use its intelligence to coordinate the UV disinfection of spaces so that it occurs before your normal cleaning process to protect your staff as well as guests. Use the data from the software to understand when to run disinfection, how often disinfections occurs, measure adherence to capacity limits, and more as a way of enforcing your other measures of preventing the spread of COVID-19 and other pathogens.

Retail

Protect your customers and staff by installing UVC lighting with market-leading safety precautions in your stores. Share that you are adding this additional disinfection layer to your current cleaning procedures to restore your customer’s confidence in entering your stores. Use the data from the software to understand when to run disinfection, how often disinfections occurs, and measure adherence to capacity limits as a way of enforcing your other measures of preventing the spread of COVID-19 and other pathogens.

FAQ

We answer your most common UVC lighting and Nexos Intelligent Disinfection software questions here.

Can I see UVC light?

You cannot see UVC light- in fact, it is called "invisible radiation!" Humans cannot see UVC light, as UVC wavelengths are beyond the visible spectrum (the portion of the electromagnetic spectrum that is visible to human eyes). The typical human eye responds to wavelengths between 380 and 740 nm, while UVC light is between 200 and 280 nm. However, it is important to note that even though UVC light is not visible to the human eye, it is still dangerous, and individuals should avoid looking directly at UVC light, especially without proper protection.

How effective is UV light for sanitization?

UV light has been proven to kill virtually all known microorganisms and is therefore one of the most efficacious sanitization practices. Studies have shown that in addition to viruses and bacteria, UVC is effective against all foodborne pathogens, natural microbiota, molds, and yeasts. Because microorganisms come with different sizes and shapes that affect their UV absorption, the required time for killing each species varies.

However, certain factors such as the duration of light exposure and surface properties also may influence the efficacy of UV lighting. For example, it is more difficult for UV lighting to penetrate greasy surfaces when attempting to sterilize a surface. When used properly in addition to standard cleaning protocols, UV lighting kills more than 99% of pathogens.

Do UV sanitizing lights really work?

Scientifically speaking, UV sanitizing lights do really work. At the most basic level, UV sanitizing lights stop cells, and therefore germs, from replicating. UV light destroys the strong molecular bonds that hold together the DNA in viruses and bacteria. This irreversible damage caused to germs can be attributed to photohydration, photosplitting, photodimerization, and photocrosslinking, all which inhibit cellular replication. In other words, UV lighting works by breaking down certain chemical bonds and scrambling the structure of DNA, RNA and proteins, causing a microorganism to be unable to multiply. When a microorganism is unable to multiply, it is considered dead since it cannot reproduce within a host and is no longer infectious. UV lighting destroys germs and renders them unable to multiply, prohibiting further infections, all without causing exposure to harsh chemicals and toxins!

Is there a specification sheet available for the current UVC lighting fixture used in this solution?

Yes, you can download the file here.

UVC Lighting Spec Sheet

How long does it take to sterilize with UV light?

As mentioned above, efficacy of UV lighting is affected by several factors, such as the distance between the light and surface, the type of surface being treated, and the type of organisms present. As a result, there is no standard time limit for sterilization using UV lighting. It is important to follow the instructions provided with your UV lighting device. If no instructions are present, a common recommendation is to sterilize for 30 min.

Does UVC penetrate glass or other surfaces?

UVC light is only able to sterilize what it comes in direct contact with, meaning that it is unable to penetrate surfaces or substances. According to the International Ultraviolet Association, standard window glass blocks almost 100% of UVC light. UVC light is also not able to penetrate the earth's atmosphere, so it is highly unlikely that it would encounter common surfaces such as windows. This is a disadvantage of UVC lighting, as surfaces must be in the direct path of UVC lighting to be sterilized. UV light in general is easily absorbed by common surfaces such as clothing, plastic, and glass, and thus it is fairly easy to be protected should an individual be at risk of coming in contact with UVC light.

Is UVC reflected? Can it sanitize surfaces that are in the shadows of an object?

It appears that UVC light is not reflected, and as mentioned earlier, it can only disinfect surfaces which it directly contacts. As a report on UV-C lighting summarized, "UV-C does not reflect off any surface. We have heard claims that low levels of UV-C reflect off walls, curtains, screens, etc., so increasing time can sufficiently sanitize surfaces of a full room. UV-C works only line of sight." Therefore, expecting effective levels of UV-C to reflect of walls or surfaces to sanitize surfaces not directly under the lighting is wishful thinking. Using multiple UVC bulbs can help ensure multiple angles of disinfecting light are distributed in a space, increasing the ability to sanitize the area with UVC lighting.

What are the disadvantages of UV disinfection?

Although UV lighting serves as a wonderful sanitation method, there are some potential dangers to consider. When in direct contact with humans, UV disinfection can be harmful. However, most UV lighting systems come with necessary shields and protection barriers to prevent any unnecessary exposure. If proper safety protocols/instructions are followed, exposure will also be avoided.

It is also important to consider that UV light must be directly exposed (not blocked by any barriers) to the surface it is to disinfect. This makes it difficult to sterilize areas with different corners and objects present. However, with the use of multiple bulbs lamps, this issue can easily be avoided.

Can you kill the coronavirus with UV light?

Since UV light has been shown to achieve a high level of inactivation of a near-relative to the coronavirus (i.e., SARS-CoV-1), it is believed that UV lighting will have a similar effect on killing the coronavirus. The radiation warps the structure of the DNA of the virus and prevents it from replicating. However, proper protocol and instruction must be followed to ensure that all surfaces with the virus be reached. It is also recommended that UV lighting be used in addition to other cleaning protocols.

Source

Can I add this to an existing building?

Yes, it will be easiest to add this to a building that already has Igor's technology installed, or at least has significant PoE technology that already exists in the space. However, the packages the Igor team has put together to install the Nexos Intelligent Disinfection into an existing conference room or space has been designed for places that do not have Igor already installed.

What safety checks does the software do before running the intelligent disinfection solution?

The actual safety checks in the Nexos Intelligent Disinfection software depend on what devices you have in your space, and what package you purchase. At a minimum, there will be an occupancy motion sensor along with a door strike sensor to tell the software if a person is in the space. After the motion sensor no longer detects motion and the door sensor has not been activated for a set period, can the UVC sanitizing lighting begin.

Our ideal recommended solution package will also include thermal people counting sensors. Combining motion detection, people counting, along with door strike sensors or access controls will ensure the highest level of safety possible. It eliminates the possibility that someone falls asleep, say in a public library, and fails to trigger the motion sensor that would stop disinfection from occurring.

If UVC is dangerous, why is sunscreen only for UVA and UVB lighting?

By definition, the shorter the wavelength of light, the more harmful the UV radiation. However, shorter wavelength UV radiation is less able to penetrate the skin. Short-wavelength UVC is the most damaging type of UV radiation, but it is completely filtered by the atmosphere (ozone) and does not reach the earth's surface. Therefore, you do not need to wear sunscreen to protect yourself from natural UVC light. It is important to use proper protection when operating with or near manmade UVC light.
