Self-powered UV blaster kills handrail germs on escalators

LG has announced the world’s first 'Handrail UV LED Sterilizer' designed to kill nasty bacteria and other microorganisms on escalator handrails.

The handrails of escalators and moving walkways (travelators) in places such as shopping centres and railway stations can easily transmit infection because they may have contact with the hands of thousands of people per day.

Up to now the usual way to disinfect them has been to wipe them down two to three times a day with hand towels.

LG Innotek’s new device is designed to sterilise the handrails by continuously disinfecting the rails during the operation of an escalator. The company also boasts that the device is easy to install and manage.

The Handrail UV LED Sterilizer is designed to wipe out 99.99 per cent of the germs on the surface of a handrail just before a passenger lays his or her hand on it. The steriliser is installed on the front part of handrail and shoots UV rays onto the handle which passes through this point.

The product blocks any sources of infection from spreading by completely destroying the DNA of germs via UV LED light with a wavelength of 278nm. LG says this light-based system is harmless to the human body since it does not use any chemicals or heavy metals.

The steriliser is just half the size of a piece of A4 paper and can be attached to a standard escalataor without making changes to the existing facility. When the escalator starts operation, the steriliser starts working immediately.

Another special feature of the steriliser is that it is a wireless device with no need for power supply. No direct electricity cost is incurred, since the product's operation relies on self-generation using the energy from the movement of the handle.

LG says that the performance and safety of the device has been approved by official institutions around the globe.

“This product is an innovative product that improves hygiene and safety at the same time,” company officials said.
