Our company has always been committed to reducing the risk of contamination and increasing safety by managing cross transmissions in many areas: surface treatment, air quality, and water disinfection. UV-C is an established and reliable technology, but solid know-how is required for effective and safe use. UV-C uses ultraviolet light to inactivate microorganisms, mainly by cross-linking thymidine nucleotides in DNA and uracil nucleotides in RNA, which block replication. UV-C systems are relatively fast and easy to use, leave no chemical residues, and do not expose workers to harmful substances.

There is peer reviewed scientific literature on UVC’s effects on SARS-Cov-2 and multiple examples of microorganisms being effected by UV-C in scientific literature that are very similar viruses, such as SARS or MERS.

There is also evidence of the effectiveness of ultraviolet rays in disinfecting air and surfaces from microorganisms that are much more complex and difficult to treat than this virus in healthcare environments, such as C. Difficile, MRSA, or even more deadly threats such as Ebola and Legionella. (Kowalski 2009)

It is estimated that the SARS-CoV-2 virus can survive on surfaces for up to nine days, based on its similarity to SARS and MERS.

Standard disinfectants are effective against SARS-CoV-2, but to provide additional protection and defend against errors in the manual disinfection process, UV-C can be used to disinfect surfaces and equipment following manual chemical disinfection. (UVC randomized Lancet ANDERSON)

“ASHRAE” (American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends consideration of ultraviolet germicidal irradiation as a way to address disease transmission on COVID-19.

The use of UV irradiation in air conditioning and air treatment systems has also been recommended for many years.
