Killing coronaviruses with UVC light

COVID-19: Since around mid-March, there has been a noticeable rise, not only in the public’s interest in ultraviolet technology and sales of ultraviolet devices. Studies have shown viruses can be killed by conventional germicidal UVC light. Visit our online shop

How does UV-C Disinfection work?

UV-C radiation is often created using low-pressure mercury discharges (germicidal radiators).

Radiation with a wavelength below 200 nm creates harmful ozone in the air. Therefore, the manufacture of UV radiators require a special quartz glass for high transmission rate for bactericidal radiation, and yet absorbs undesirable UV radiation with a wavelength below 200 nm. This allows UV-C radiators to produce a negligible amount of ozone during the first 100 hours of lighting.

The most significant bactericidal effect occurs at radiation wavelengths from 250 to 270 nm. The bactericidal mechanism involves the absorption of UV-C radiation energy by nucleic acids and proteins, leaving them unable to perform vital cellular functions.

The direct measure luminaires:

• Agaline UV-C – beam for T8 light sources. Mounting on an adjustable holder on a wall or floor mounting on a mobile stand.
• Universal UV-C – luminaire dedicated for surface mounting. To be placed on a construction of a modular ceiling or to be mounted in plasterboard ceiling with adaptor frame.
  A compact fluorescent TC-L is a source of radiation.
• Oktan UV-C – TC-L compact fluorescent luminaire dedicated for on wall mounting. Possible is also mounting on mobile stand.
• UV-C STERILON – UV-C STERILON lamps emitting ultraviolet light are one of the most effective devices capable of removing viruses, bacteria, fungi from the surface or destroying the DNA or RNA of any exposed microorganisms. Possible is also mounting on mobile stand.

The flow-type luminaire:

• Airstream UV-C – a bactericidal luminaire with forced air circulation, equipped with T8 fluorescent lamps and adapted to be mounted on wall, ceiling or on stand.
• UV-C Sterilon Flow 72W luminaires emitting ultraviolet (UV-C) light are one of the most effective devices capable of removing viruses, bacteria, fungi from the surface or destroying the DNA or RNA of any exposed microorganisms. It is available as dual function products.

Choosing the correct Luminaire

UV-B - medium wave 315 nm - 280 nmIt has basic application in therapy. Creates provitamin D. There is a pigmentation and erythemal effect.

UV-C - short wave 280 nm - 100 nmIt has a strong bactericidal and germicidal effect. Causes skin burns (Eritema) and conjunctivitis (conjunctive effect).From a practical point of view, we can assume that we will achieve a sufficient degree of microbiological purity* using:-

• 15 W lamp on an area up to 6 m2
• 2x15 W lamp on an area up to 10 m2
• 30 W lamp on an area up to 12 m2
• 2x30 W lamp on an area up to 18 m2

HOW TO USE?

2 - 8 hrs: depending on the type of room (doctor's office, patient | treatment | operating room).

15 - 20 min: to obtain an immediate disinfection of air in the room (e.g. between 2 treatments).
