The Defence Research and Development Organisation (DRDO) has introduced two products which can enhance the operations at public places during the COVID-19 disinfection process.



The two units are called the automatic mist based sanitiser dispensing unit and UV sanitisation box and hand-held UV device.



Automatic mist based sanitiser dispensing unit is a contactless sanitiser dispenser which sprays alcohol based hand rub sanitiser solution for sanitisation of hands while entering the buildings/office complexes, etc. It is based on water mist aerator technology, which was developed for water conservation.



Ultraviolet C ;ight based sanitisation box and hand held UV-C consists of a shorter, more energetic wavelength of light. It is particularly good at destroying genetic material in COVID-19. The radiation warps the structure RNA which prevents the viral particles from making more copies of themselves. The UV-C kills microbes quickly. Sanitisation of the items by employing UV-C light avoids the harmful effects of the chemicals used for the disinfection. This is environment friendly and is a contact free effective sanitisation method.



The UV-C box is designed for disinfecting personal belongings like mobile phone, tablets, purse, currency, cover of office files, etc. COVID-19 virus will be deactivated by using UVC lamps in one minute placed equi-distantly in a box with UV dose of 100 mJ/cm2. The UV lamps used in the sanitisation box also emits 185 nm which produces ozone and is able to take care of the unexposed area on the surfaces of the objects placed in the box.
