About UV Disinfection - Tube Light - JenAct Ltd


UV Air Disinfection Technology:

Destroys Airborne Viruses, Covid-19,

Improves Air Quality

UV Air Disinfection is a process using Germicidal UV Light, a proven technology for reducing bacteria and harmful microorganisms, to destroy Covid-19, 99.9% of airborne viruses, Coronavirus, Influenza, MRSA, Tuberculosis, E-Coli, other bacteria and moulds. UV Air Disinfection applications, suitable for HVAC, destroy microbes from air ducts and evaporator coils, sterilize and improve air quality . UV Air Disinfection solutions provide safe, disinfected workplaces and are suitable for surgeries, dentists, hospitals, hair salons, offices, waiting rooms, improving the indoor air quality of residential, commercial, institutional, healthcare and medical environments. We offer both Conventional UV and Microwave UV installations which can be used to:

  • Dramatically improve indoor air quality

  • Destroy Covid-19, Coronavirus, airborne viruses, bacteria, mould, chemicals, VOCs and odours

  • Reduce airborne infection rates.

  • Maintain clean evaporator coils, free from mould and other microbial growth

  • Improve energy efficiency and reduce maintenance costs in HVAC

  • Reduce absenteeism and building related illnesses

UVC at approx. 250260 nanometres resonates and disrupts DNA/RNA in cell nuclei and viruses, destroying it. Germicidal UV Air Disinfection Systems are very efficient in achieving high disinfection rates of biological contaminants (viruses, bacteria, yeasts and moulds) as well as reducing odours, promoting reactions to inactivate some chemicals and volatile organic compounds (VOCs). Each biological contaminant requires a specific UVC dose in order to achieve its destruction/inactivation.

UV Air Disinfection can protect occupants from Biological Warfare Agents.


In general, smaller contaminants such as viruses, require lower UVC dose than larger contaminants such as bacteria and moulds. For example, Influenza A virus requires a UVC dose of approximately 6mJ/cm2 in order to achieve 99.9% inactivation (3 log kill). On the other hand, it requires more than 1000mJ/cm2 to achieve similar inactivation level of Aspergillus Niger fungi.


Over the years we have acquired valuable expertise in both conventional UV and microwave UV systems design.   Our unique UV sizing software is used  to determine the disinfection levels achieved with various UV systems.
