A GERMAN supermarket is trialling UV-C disinfection lighting to kill coronavirus in the air.
The Edeka store Hamburg has installed 31 Philips UV-C disinfection upper air luminaires to cover the 1,300 square metre store, one-fourth the size of a football field.
The store is also using one Philips BioShift UV-C chamber to disinfect objects and shared devices such as hand scanners.
UV-C breaks down the DNA or RNA of microorganisms, including viruses and bacteria, thereby rendering them harmless.
The mercury UV-C lamps used in the Edeka supermarket emit a peak of radiation at 254 nm, which is near the peak wavelength for germ deactivation, and therefore suited for disinfecting air, surfaces, and objects.
The luminaires are installed at a height of 3.2 to 3.5 metres on columns and walls.
The fittings are all equipped with shielding and optics to prevent exposure to UV-C radiation, so employees can safely fill the shelves, while customers find their groceries.
They continuously disinfect the air that flows through the upper areas of the store thanks to natural convection, or air circulation.
This also ensures that the disinfected air flows back to the lower part of the store space and mixes with the air.
‘We are proud that we are the first supermarket in Germany to provide both our shoppers and our employees an additional layer of protection,’ Dr. Dirk-Uwe Clausen, managing director of Edeka Clausen told Lux.
‘We’ve been working with Signify for many years in the field of lighting and have a common goal to provide our customers with the best possible shopping experience.
‘The health of our customers and employees is our top priority and we’re committed to creating a safe and high-quality shopping environment for our customers.
‘Our self-employed merchants pay strict attention to compliance with the applicable hygiene and clearance regulations in their stores,’ said Stefan Giese, managing director of EdekaNord.
‘Over the last decades we have developed a strong application competence in the field of UV-C disinfection,’ said Christian Goebel, sales director public at Signify DACH.
‘Were very pleased that we can give people in many everyday areas a piece of new normality with our products, and we hope that many retailers will follow Edeka’s example.’
The company warns that UV-C light should always be used by professionals in accordance with the safety requirements and instructions to avoid humans and animals from being exposed to protect their skin and eyes from potential damages.
