Violeds UV LED technology achieves another breakthrough

In December 2020, Seoul Viosys just announced that the test results of the Korea Testing Laboratory (KTL) proved that the air conditioning and heating system equipped with Violeds UV LED modules can kill 99% of the airborne transmission in a 60 cubic meter room within 30 minutes virus. The virus used in the test is the bacteriophage PhiX174, and its ultraviolet C dose is close to SARS-CoV-2 (coronavirus 2). 

On January 7, Seoul Viosys announced that Violeds UV LED technology has passed new research tests.

According to official sources, Seoul Viosys and SETi conducted tests in December 2020 at KR Biotech, a South Korean research institution specializing in bactericidal detection of new coronaviruses, which proved that Violeds UV LED technology can quickly and effectively inactivate 99.437% of new coronaviruses in one second.  

During the test, the research team exposed the new coronavirus to the Violeds UV LED module for 1 second, 3 seconds, and 5 seconds, respectively, and found that the sterilization rate of the UV LED module within 1 second was 99.437%. 


Test results show that Violeds UV LED technology is an effective means of sterilization and disinfection. It is suitable for killing airborne viruses and viruses in water systems. It can also be used in hospital wards and other places where people with new coronary pneumonia are infected. Currently, SETi has two disinfection samples using UVC LED technology on sale.
