This air conditioning and heating system testing with Violeds module resulted in 99% disinfection of the airborne viruses in a 60m³ room within 30 minutes. The virus used in testing is bacteriophage PhiX174 which is similar in UVC dosage to SARS-CoV-2 (Coronavirus 2).

Violeds module is an optimized solution to simultaneously enable disinfection of various viruses and bacteria in the air, as well as air purification by disinfecting the air drawn into the air conditioner and eliminating viruses in the air. The module device can be easily installed in the air conditioning and heating systems in use.

Seoul Viosys has been running a campaign to install Violeds module devices in air conditioners and heaters of applicants from August 2020 targeting public and multi-purpose facilities to help reduce both air and surface pathogens in indoor spaces.

“As the impact of the COVID-19 pandemic, according to Yole Développement, a market research company, the global market for UV LEDs is expected to grow into USD 2,786 million in 2025. So Seoul Viosys will continue to offer our patented UV LED technology with harmless effects on humans unlike mercury lamps,” said an official at Seoul Viosys.
