What is UVD robots? Can UV disinfection robots help to combat COVID-19?

UVD robots are portable enhanced environmental disinfection systems (robots) that feature ultraviolet-C (UV-C) light or hydrogen peroxide vapor (HPV) to complement infection control protocols already in place to battle hospital-acquired Clostridium difficile (C. diff), methicillin-resistant Staphylococcus aureus (MRSA), and other multi-drug-resistant organisms. Disinfection robotics evolved out of the need to reduce HAIs without incurring additional labor costs.

UVC robots specifically employ the highly germicidal 253.7 nm bandwidth to cause photochemical damage to cellular DNA and virus RNA. This biological damage inactivates the cell by preventing replication and therefore infection capability. Germicidal efficacy is determined by the overall dose of UVC, which is a product of lamp output (i.e., intensity) and exposure duration. The surface disinfection rate can be 99.99%.

In this article, we will introduce the Dry Fog UVD Robots and the autonomous mobile UVD Robots.

Dry fog spraying UV disinfection robots Introduction

The intelligent dry fog UVD robots can atomize a variety of disinfectants, such as  H2O2 (hydrogen peroxide ), HOCI/HICO (Hypochlorous acid), and other disinfectants, into super dry mist and disperse to the disinfection area in high-speed airflow. It could reach the disinfection area by autonomous navigation,  obstacle avoidance, and movement, and disinfect the target 360°. It could also support iPad control for quick and central disinfection.

The customers can choose the sterilization function flexibility. Either use the dry fogging sterilization or using the UV-C lamps sterilization. The density of the dry fogging is determined by the concentration of the disinfectants. Although people can exposure to some low level or low-density disinfectants, some chemical disinfectants are harmful. To ensure the safety and health of employees engaged in handling disinfectants, a carefully planned chemical safety program is essential. Please refer to your local regulations and laws to ensure the safety and health of employees. It’s highly suggested to arrange the sterilization when space is in unoccupied mode. There are 2 groups of UV-C lamps are used for sterilization. Only one type of sterilization can work each time, either dry-fogging or UV-C sterilization. They cannot work at the same time.

The UVD Robot is used as part of the regular cleaning cycle, and aims at preventing and reducing the spread of infectious diseases, vira, bacteria.

How will the UVD robots work?

AHUS-R UVD robots are a combination of dry-fog spraying disinfection and UV short-wavelength disinfection.

  • Dry-fog spraying disinfection

The disinfection performance is achieved by diffusing nanoscale liquid beads to the disinfection area. The mist can be called “dry”  when the average diameter of the droplets is less than 10  microns. The dry mist will not settle or move randomly, nor aggregate to large droplets; they will rebound when contacting the surface and will not rupture to wet the surface. This characteristic determines that they could cover some hard-to-reach areas. Dry-fogging volume can reach 3000g/h. No residue.

  • Short-Wavelength UV-C Sterilization

Studies have shown that UVC at 254 nm 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.

UV sterilization also is known as UV disinfection or ultraviolet germicidal irradiation (UVGI) 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.

Additional function: Infrared Thermal Scanning, Imaging, and Temperature Measurement

Dual-light AI faces recognition, multi-person temperature measurement at the same time for highly effective infection detection and control. With an intelligent temperature detection recording system.

Combining AI core algorithms to realize the recognition and tracking of portraits, and save the face and temperature in the cloud, support high-temperature alarm and multi-machine screen monitoring, and the temperature measurement error is ±0.3℃ for 0.8-2 meters detection, ensuring that it will not be in the case of large passenger flow There are false positives and under-reports.

High-risk personal locking, and manual remote monitoring. Suitable for public places such as airports, exhibitions, hospitals, stations, museums, and other Crowed areas.

Autonomous mobile UVD robots

AHUV-Rs Autonomous mobile Ultraviolet Disinfection (UVD) robots can be used for unoccupied space disinfection. The software and sensor-based emergency power-off function will work when it detects personal during the disinfection. Once people leave, it will automatically switch to the work model and finish the disinfection process again. It’s safe and no person will exposure to UV-C lights.

With 8 groups of short-wavelength UVC lamps, the UVD robots provide 360-degree high-intensity room disinfection and no-contact option to eliminate human error caused by labor cleaning. AHUV-Rs UVD robots are designed for regular cleaning routine for infection controls and reduce HAIs in hospitals and other areas and generate revenues. It’s easy to install and use, and can be moved to treat/sterilize one after another area.

With the detection sensor and emergency stop button, the UVD (UV Disinfection) robot (120-240V/2A Charging Pile Input) is a safe and effective autonomous mobile solution for air and surface disinfection.

With 8 groups, 40W each, short-wavelength UV-C lamps, the UVD robot can produce high-intensity UV irradiation to prevent and reduce the spread of infectious microorganisms in the environment by breaking down their DNA structure.

The UVD robot is pre-fitted in our factory, and it’s easy to install and operate.

What makes the UVD robots outstanding over the existing manual cleaning system?

  1. Fully autonomous allowing the robot to move position without human interaction drastically reducing shadow areas.
  2. Increased mobility ensuring closer proximity to all high touch surfaces increasing the intensity of the UV-C light.
