This equipment works on the principle of Ultra Violet radiation emitted from a Germicidal UVC lamp that kills up to 99.9% of most viruses, airborne bacteria and mold spores by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. Using this technology DLS, Visakhapatnam fabricated the sanitizers.
Timer Based Currency Sanitizer fabrication:
• Wooden casing of the sanitizer box.
• One 4W UVC light is fixed on the roof/top of the box facing downward.
• One sliding tray is provided in which the currency is put for sanitization, having sliding facility to move in both directions.
• Timer circuit to switch off UVC light after 10 seconds after pressing the push button switch and provided with a green LED which indicates equipment is ready for another operation.
Working of the equipment:
A passenger have to place the reservation form and currency notes in the tray, the railway staff pulls the tray into the UVC light provided in the box and presses the push button switch that makes UVC light to glow for 10 seconds along with the buzzer indication. Just after completion of 10 seconds both UVC light and buzzer stops working and the green light will glow indicating sanitization is completed and ready for another operation.
Thereafter railway staff pulls the tray towards him/her and collects the money and puts the reservation tickets & change, if any, into the tray and repeat the process before pushing it towards the passenger. This machine can also be used for sanitizing mobile phones, wallets and any other items which fits inside the tray.
