UV-C AIR DISINFECTOR

UVC DISINFECTION FOR YOUR COMMONLY-USED AREAS – EVEN EFFECTIVE AGAINST CORONAVIRUS

SARS-CoV-2 viruses are mainly transmitted via aerosols released into the air when you breathe. UVC air disinfection can be used to reduce the germ load in the immediate environment. The chemical-free UVC disinfection process is already used to a high degree of success in the production and healthcare sectors.

Thanks to their elegant design, Hönle UVC air disinfection systems are perfect for inconspicuous operation in enclosed, commonly-used areas.

UV-C disinfection from HÖNLE

Following the emergence of SARS-CoV-2 pathogens, disinfection and sterilization have become issues that affect all public and private areas.

LEDVANCE GmbH and Dr. Hönle AG cooperation partner in room air disinfection. With the SteriWhite Air Q series we offer you an effective way of disinfecting your room air - even for large rooms with a high number of occupants, such as in schools, universities, restaurants or large meeting rooms.

LEDVANCE UV-C AIR DISINFECTOR

The LEDVANCE UVC AIR DISINFECTOR not only contributes to better and healthier air quality in office, commercial and practice rooms in corona times.

The high-tech device enables particularly effective, completely chemical-free room air purification - and this continuously when people are present. This device is particularly suitable for individual offices, small meeting rooms or practices.

HÖNLE STERIWHITE AIR Q

THE SOLUTION FOR UVC DISINFECTION IN HOSPITALITY, HEALTHcare, EDUCATION AND OFFICEs

Thanks to their elegant design and very quiet operation, they fit discreetly and yet effectively into your rooms. For SARS-CoV-2 viruses, an inactivation rate of 99.99% could be detected on surfaces (by the S3 laboratory of the Goethe University Frankfurt). The devices for UV-C circulating air disinfection can be used in many areas: offices and meeting rooms, law firms, doctor's offices and waiting areas, old people's and nursing homes, daycare centers, schools and educational institutions as well as restaurants and hotels.

How UVC disinfection works in a closed system

Find out in the video from our partner, using the SteriWhite Air Q115, how the devices successfully make your room air safer by using UV-C disinfection. Without the use of chemicals and without the production of harmful ozone - while you and others are in the room.

Equipped with high-performance UVC technology, the design of the SteriWhite Air Q remains elegant and unobtrusive. Due to its quiet noise level during operation it is even perfectly used in training classrooms. SteriWhite Air Q is available as a stand-alone unit as well as for ceiling or wall mounting.

With an air flow rate of 115 m³ up to 900 m³/h, depending on the device version, (for normal room air: 20 °C, 50% humidity), SteriWhite Air Q with its UVC air disinfection is a great supplement to existing hygiene measures in the hospitality sector, schools or even medical practices. Several disinfection devices could be used depending on the size of the space.

To calculate the number of devices you need, please use our air disinfection calculator.

The UVC air purifier calculator provides instructions on which device to use and which amount is recommended for a room. The calculation is based on the scenario that exactly one person is infected in the room and stays with other people in the room for a period defined by the tool user. It is assumed that the room air is 100% virus-free at time 0.

Recommendation for the number of devices: The recommendation is based on the one hand on the desired air exchange rate and on the other hand on the number of people in the room and depends on the use of the room. The air exchange rate is defined as the total air throughput of the devices divided by the room volume.
- We recommend an air exchange rate of at least 2.5 (standard)
- The risk of infection is increased in rooms that are visited by a large number of different people within a day (meeting rooms, waiting rooms, etc.) and we recommend an air exchange rate of 4 (increased safety).
- In addition, we recommend a minimum air flow rate of 25m³ / h and person, regardless of the size of the room. The recommendation is based on Table C.4 in EN 16798-2 Overall Energy Performance of Buildings - Ventilation of Buildings. Our recommendation is based on the ventilation rate for an expectation of category II air quality.
- The Federal Environment Agency recommends an air change rate of 6 (school) for schools regardless of the number of people in the classroom.

The calculation of the virus concentration and the likelihood of infection follows the work "Predicted infection risk for aerosol transmission of SARS-COV-2" by Prof. Dr.-Ing. M. Kriegel et al, Hermann Ritschel Institute, Technical University Berlin.

The virus quantum model was taken from "Estimation of airborne viral emission": Quanta emission rate of SARS-CoV-2 for infection risk assessment "by G. Buonanno et al, University of Cassino and Südlazio. The following modeling input parameters were used:
- cv 5.0E + 08 (viral load in sputum, viral RNA copies / ml)
- ci 0.05 (ratio between the infectious quantum and the infectious dose, expressed in viral RNA copies)
- Qb depending on the activity (tidal volume) - standard value 0.54 m³ / h
Please note that cv varies greatly depending on the individual and the time of infection. The probability of infection varies greatly depending on the input parameters cv, ci and Qb. However, the relative reduction in the risk of infection by an air purifier does not change as much.

The natural virus decay was calculated for 20 ° C, RH 30% and UV index 0 with the computer of the Department of Homeland Security and determined with D50 = 2.72h.
https://www.dhs.gov/science-and-technology/sars-airborne-calculator
The calculator is based on the following publication:
P. Dabish et al, "The influence of temperature, humidity and simulated sunlight on the infectivity of SARS-CoV-2 in aerosols", Aerosol Science and Technology, Volume 55, 2021 - issue 2

The air sanitizers are believed to have a virus inactivation rate of 99.9%.
A natural air change ACH of 0.35 is assumed for the reference case.
 

 

Air flow rate / Clear air delivery rate (CADR): The clean air flow rate is the volume of air that flows through the device (s) per hour. A higher CADR leads to a lower virus concentration.

Air change rate: The air change rate (abbreviated ACH = Air Change Rate) is equal to the total CADR of the devices in the room divided by the room volume. A higher air exchange rate leads to a lower virus concentration.

Disinfection in closed rooms

Thanks to their elegant design, Hönle UVC air disinfection systems are perfect for inconspicuous operation in enclosed, commonly-used areas. Use the disinfection devices to supplement other hygiene measures in many different places: hospitality, education facilities, medical practices and offices.
