What is UV-C Disinfection?

What is UV-C Disinfection?

No-touch disinfection is becoming more and more popular as facilities need to be vigilant at killing germs and bacteria from surfaces that are frequently touched by guests.

Finding ways to disinfect the surfaces and objects in your facility quickly and safely is an important part of reducing the risk of spreading illness-causing germs from person to person.

For some facilities, using chemical disinfectants to kill germs on objects and surfaces may not be a viable option because the chemicals can affect occupants or building guests.

For example, disinfecting with chemicals increases the risk of respiratory discomfort and can require more time than using other high-volume disinfection methods.

Unlike other disinfection methods, UV-C disinfection doesn’t require any chemicals, which makes it an option for disinfecting surfaces in your facility. 

In this article, we’ll define UV-C disinfection and explain how using this method can help reduce the likelihood of spreading germs and bacteria in your facility.

What Is UV-C Disinfection?

UVC technology uses

Ultraviolet-C disinfection, or UV-C, is a no-touch disinfection method that uses Ultraviolet radiation to kill common pathogens that cause illness. 

The radiation is artificially created with specialized UV-C lamps on the machine.

The light from the lamps needs to be able to make contact with the surfaces being disinfected in order to effectively kill the bacteria. The amount of contact time needed is dependent on the specific bacteria being targeted. 

For specific guidance on how long a room would need to be exposed to UV-C disinfection, you will need to consult the device manufacturer’s guide.

Is UV-C Disinfection Safe?

There are three types of UV radiation that are classified according to their wavelength (nm). 

Each type of radiation differs in its ability to kill germs and bacteria and how likely they are to penetrate the skin.

UV-C (100-280 nm) is the strongest type of radiation but it doesn’t penetrate the skin during use. UV-C used for disinfection is artificially generated by specialized lamps on the device to kill germs on various surfaces. 

At effective dosages, UV-C radiation is lethal to common pathogens such as SARS-CoV-2, Influenza, MRSA, and C. diff. 

NOTE: UV-C radiation can cause burns to the skin and eye. You should avoid direct exposure and never look directly into a UV-C lamp. 

How Does UV-C Disinfection Work?

To disinfect, the UV-C disinfection device should be positioned in the area or location that provides the best coverage for the surfaces to be disinfected in your facility. 

UVC disinfection in healthcare

Meaning, the light produced from the device will need to be able to have full contact with the areas being disinfected for the recommended contact time. 

The UV-C lamps cannot disinfect through objects, so your staff will need to make sure that the light produced from the machine can make contact with the various areas that need to be disinfected.

If the contact time for the specific kill claims of the machine is not met, the germs on the surfaces will not be killed and the area will not be thoroughly disinfected. 

In the event that the UV-C device can’t be positioned to disinfect the entire area, you may need to move the device around the room during disinfection for the best and most effective coverage.

A 900 sq/ft room can be disinfected in about 3 minutes for most pathogens with a UV-C device. This allows you and your cleaning team to clean and disinfect large areas.

Where Can UV-C Disinfection Be Used?

For the past 20 years, UV-C disinfection has been used in healthcare facilities to reduce the risk of healthcare-acquired infections (HAIs).

More recently, other facilities have also begun implementing UV-C disinfection to treat surfaces where large areas needed to be disinfected in less time. 

PPE undergoing UVC Disinfection

This includes:

  • Hotels
  • Schools
  • Government Offices
  • Fitness Centers
  • And More

UV-C disinfection is hospital-grade technology that is perfect for use where using harsh chemicals may be harmful to the people in your building.

Keep in mind that UV-C lamps can degrade some materials like plastic, polymers, and dyed textile. If you have these materials in your facility, you should exercise caution when using these devices to disinfect those surfaces.

It’s important to note that the effect of UV-C light on these surfaces is typically no more severe than the standard disinfectants you’re probably already using.

How Much Does UV-C Disinfection Cost?

The specific cost of UV-C Disinfection depends on the machine that you’re looking to purchase for your facility.

While UV-C disinfection generally costs more than other types of No-Touch Disinfection, the amount you can save is also higher than other types of NTD devices.

These machines can seem like a costly purchase upfront, but the return on investment that your business will see can save you a significant amount of money on labor and chemicals.

What Types Of UV-C Disinfection Devices Are Available?

Imperial Dade offers two of the most prominent UV-C devices on the market to help you and your cleaning staff achieve effective and efficient disinfection in your facility.

Two specific devices that will make disinfecting the surfaces in your facility easier and less time consuming are:

  1. UBTECH® ADIBOT System
  2. Diversey Moonbeam ™  3

Both of these machines are portable using wheels on the bottom of the device. 

The ADIBOT System is more costly than the Moonbeam™ 3, but the ADIBOT is better for large facilities with multiple large areas that need to be disinfected. 


There are two UBTECH® ADIBOT systems that are available to disinfect your facility’s surfaces.


The ADIBOT A can be used fully autonomously for robotic disinfection of specific areas in your facility. 

There’s also a stationary model, the ADIBOT S, that can be moved manually from space to space on omnidirectional wheels.

Disinfection Capabilities: 

Each UBTECH® ADIBOT has a sleek, vertical design that allows it to disinfect throughout your facility.

The ADIBOT A is equipped with 16 UV-C bulbs over the 66.5-inch height of the machine. This machine can achieve disinfection of upper and lower surfaces in the building.

The ADIBOT S has 8 UV-C bulbs that run the entire 74.8-inch height of the machine. This machine can cover a full 360 degrees top to bottom coverage during disinfection.


The ADIBOT A UV-C device can work autonomously so that your cleaning staff does not have to spend time operating and moving the machine through your facility. 

While the ADIBOT S does not move from space to space on its own, once set up, the unit is capable of disinfecting about 900 square feet in 3 minutes while your cleaning staff performs other duties.


The ADIBOT S is stationary and can be operated using a remote to keep your staff safe from radiation exposure.

The ADIBOT A is autonomous, so your staff does not need to operate the machine at all to disinfect your facility. 

For both pieces of equipment, your staff can also use a remote control or the app to perform disinfection.

Power Source:

The ADIBOT A is battery-powered, which gives your cleaning staff increased flexibility when using the system to disinfect the surfaces in your building.

The ADIBOT S is a corded device that can be used as soon as it’s plugged into a power source. 

Diversey Moonbeam™ 3

This UV-C disinfection device is portable and disinfects high-touch surfaces quickly. The Moonbeam™ 3 is easy to use and efficient for high volume disinfection.

Disinfection Capabilities: 

The Diversey Moonbeam™ 3 has three adjustable UV-C heads with 2 bulbs each that disinfect both horizontally and vertically. They can be positioned in various combinations in order to maximize the efficiency of the cleaning machine.

The UV-C heads of this machine are able to disinfect between 6 to 84 inches.
