Features
The Smiths Detection Ultraviolet (UV) Light standalone module was developed to reduce transmission of bacteria and viruses by disinfecting checkpoint trays to restore passenger and staff confidence.
Ultraviolet germicidal irradiation has been used in disinfection applications for over 100 years, often in medical sanitation and sterile work facilities with high hygiene requirements. The same, proven technology was leveraged by Smiths Detection to develop the UV Light standalone module for tray disinfection. Low pressure mercury lamps emitting short-wavelength ultraviolet C light are used to kill or inactivate microorganisms by disrupting their DNA or RNA, leaving them unable to perform vital cellular functions.
To achieve deactivation of up to 99.9%, the system is designed to expose the trays to veryhigh levels of UV-C light and to place the lamps around the tray, allowing the tray to be disinfected from all sides.
As UV-C light can be harmful, the kits are safely shielded from any leakage using robust metal housing and following relevant safety standards such as BS EN ISO 15858:2016. Interlocks automatically shut off the UV-C lamps in the event of an emergency stop, tray blockages on the conveyor or opening the module.
Wavelengths shorter than 240nm, that are mainly responsible for the potentially harmful generation of ozone by UV light, are blocked by special materials within the construction of the lamps.
These standalone kits can be used flexibly at any checkpoint regardless of the scannertype and tray handling technology in use. With a belt speed of 0.2m/s they are capable of sanitizing up to 600 trays per hour.
