A UVC light-based room sterilization system designed by Raja Ramanna Centre for Advanced Technology, Indore, a unit of Department of Atomic Energy, Govt. of India and Manufactured by M/s Research India
The “NEELBHASMI” is an Ultraviolet-C (UVC) light based mobile system intended for inactivate various micro-organisms including corona viruses the air as well as the surfaces of various objects inside a room at research centres, hospitals, doctors’ offices, or any other places of work. It is equipped with eight lamps which emit UVC radiation that kills bacteria and viruses by destroying the molecular bonds that hold their DNA (or RNA) together. The system has a height-adjustable central vertical tower whose top end is attached with four detachable arms, each fitted with two UVC lamps, one facing up and the other facing down. Each of the arms can be moved at any angle between 30 and 145 degree with respect to the vertical tower thereby allowing the user to maximally illuminate surfaces of any orientation for efficient sterilization. The height adjustability of the vertical tower further allows the user to place the lamp from the target surface as close a distance as possible so as to be able to sterilize it in a minimum time. The bottom end of the vertical tower is mounted on a solid metallic base having nylon wheels that provide the system the desired mobility to move across the room. The UVC lamps of the system can be remotely switched on and off from outside the room (where it is to be used) so as to cause no exposure of UVC radiation to the operator. The timer provided with the system allows one to set the time duration over which the lamps are required to remain switched on for the purpose of sterilization. The motion sensor of the system will immediately switch off the lamps in case any inadvertent movement by any person inside the room takes place when the system is in use. The system is capable of sterilizing surfaces kept within one-meter distance from the tower in less than 5 mins. For sterilizing a room with a floor area of 10 square meter it will take around 45 minutes.
