Ultraviolet (UV) light is invisible to human eyes. It can be subdivided into three categories:
UV-A (from 315 to 400nm)
For use with curing, sun tanning and insect traps.
UV-B (from 280 to 315nm)
For medical use (i.e. phototherapy to treat skin conditions, including psoriasis).
UV-C (from 200 to 280nm)
For disinfection purposes and germicidal application.
HOW DOES IT WORK?
UV-C radiation can break the DNA and RNA of bacteria, viruses and spores, meaning that they leave them harmless. There are no known micro-organisms resistant to UVC.
UV-C technology has been used safely and effectively in hospitals and governmental buildings for more than 40 years.
Most UV-C solutions utilize conventional lighting, with LED now improving in efficiency
The peak output of our germicidal lamps (253.7nm) is close to the maximum effectiveness of UV-C (265nm)
WHY USE UV-C AS A DISINFECTANT?
Reduce the risk of exposure for guests and staff
Make guests and staff feel better protected
Save cost by reducing disinfection cycle time
Prevent excessive spending on chemical sanitizers
Applications: Looking at just surface and air, there are numerous real-world segments where UV-C lighting is a viable disinfection solution.
VIRUS TRANSMISSION OCCURS THROUGH:
Direct air-borne transmission between people
Indirect air-borne transmission through air flows
Indirect surface-borne transmission via contaminated surfaces
UPPER AIR - HOW DOES IT WORK?
Upper air device - What is it?
The device contains one or several UV-C lamps and electronic ballast.
The UV-C beam is shaped by a reflector, with or without louvres.
Louvres allow for a beam shape as horizontal as possible, which avoids reflection on the ceiling. These configurations are used for low ceiling height, as for example offices, standard rooms, etc.
Versions without louvre are usually used when there is a wide space to cover between the ceiling and the device, as for example warehouses.
In both cases, care should be taken to limit the maximum irradiance at the level where people are present. This can be simulated and/or measured on-site to ensure maximum safety.
Upper air - How does it work?
The device radiates UV-C only in the upper part of the room thanks to optics and louvres, enabling a safe use for people present in the room.
As it is used even when the room is occupied, the complete upper layer of air is consistently exposed to the UV-C rays.
The natural movement of air enables all air particles to be irradiated by UV-C rays. This movement can be helped by mean of mechanical ventilation.
As a result, a wide volume of air is permanently treated, inactivating all pathogens.
UV-C Upper Air Using UV-C in a safe way
Like any disinfection system, UV-C lamps and devices must be used properly to be safe.
UV-C light can cause a severe sunburn-like reaction to your skin and similarly, could damage the cornea of your eye, if exposed... this is very painful. It is therefore key, that lamps are always shielded from direct radiation.
All products need to follow the standard product safety releases and approbations.
No medical claims can be made. Medical application needs clearance from Legal (local laws apply).
All products require at least -
An Instructional Safeguard AND
A Time Safeguard OR an Equipment Safeguard OR a Containment Safeguard.
