What is UV-C?

Ventilation systems and air filtration are common knowledge. Outside high risk biohazard environments, the use of Ultraviolet Light (UV) to sterilise and disinfect air and surfaces is less well known. UV electromagnetic radiation with wavelengths shorter than visible light. Ultraviolet Light can be broken down into various ranges. The short-range is UV-C and is commonly known as “Germicidal UV.” For over 100 years, short-wave UV-C has been used for specialist high-care, clean and sterile industries to protect human health against Pathogens and now, redeployed by us as part of the blend with better air and ventilation, to help restore everyday life.

A Brief History of UV Light Though the Decades.


UV radiation was discovered in 1801 when the German physicist Johann Wilhelm Ritter observed that invisible rays just beyond the violet end of the visible spectrum darkened silver chloride-soaked paper more quickly than violet light itself. He called them deoxidising rays to emphasise chemical reactivity and to distinguish them from heat rays, discovered the previous year at the other end of the visible spectrum. The simpler term chemical rays was adopted soon afterwards, and remained popular throughout the 19th century


Arthur Downes and Thomas Blunt published a paper describing the sterilisation of bacteria exposed to short-wavelength light. UV has been a known mutagen at the cellular level for over 100 years.


The Nobel Prize for Medicine was awarded to Niels Finsen for his use of UV against lupus vulgaris, tuberculosis on the skin.


UV-C was first used to disinfect the municipal water supply of Marseille, France.


Westinghouse developed the first commercial UV-C germicidal lamps. They were used primarily in hospitals. World War II, UV-C was used for sterilising air in hospitals, kitchens, meat storage and processing plants, bakeries, breweries, dairies, beverage production, pharmaceutical plants and animal labs - anywhere microbiological contamination was a concern. 

1939. sterilAir AG are born.


UV-C was incorporated into air handling equipment. It became a major component in the control and eradication of tuberculosis. The first self-produced devices with up to four UV-C light bulbs were installed in rooms with a high number of people.


During the 1960’s, concern about microbes lessons with the introduction and increasing availability of new drugs and sterilising cleaners. As mechanical ventilation becomes more popular, UV-C performance suffers due to the lack of effective UV-C performance in cold-air settings. 


Technological Improvements - Concerns over chemical use and improvements in UV-C lamp manufacturing caused more organisations and companies to revisit UV-C.


UV-C was pioneered into significant water treatment processing for municipal systems as well as for treatment of swimming pools. The introduction of UV-C into HVAC systems is pioneered in 1996 and was used to KILL Vaccine resistant “SUPER-BUGS” in Hospitals.


PP-L traces its roots back to when highly respected Chartered Engineer, Paul Waldeck, founded a Consultancy specialising in designing safety critical environments in pharmaceuticals, biosciences, food manufacture, laboratories, nuclear, and rail. Over 20+ years, he built it to be a global technology leader in those specialist sectors, and also conventional environments for offices, hotels, residential, ports, airports, logistics and manufacturing.
Post-sale of that business, Paul teamed up with Martin Badley of MBMS, Electrical & HVAC Engineering to continue that passion for technology, problem solving and human safety.


Recent technological advancements have made it possible for UV-C disinfection technology to be deployed in an ever, expanding field of applications including: Water, Air, Surface and mobile.

sterilAir AG, one of the worlds oldest and most experienced companies in the area of manufacturing and development of UV-C disinfection devices and components signed an exclusive partnership agreement with Pathogen Prevention Ltd (PP-L)sterilAir AG, the world’s oldest and most experienced company active today in the areas of manufacturing and development of UV-C disinfection devices, signed an exclusive partnership agreement with Pathogen Prevention Ltd (PP-L), a British Health Tech specialist whose roots can be traced 25 years in the fields of engineering design, installation, commissioning and maintenance for the hygienically clean and sterile industries.
