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
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:
The flow-type 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:-
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).
