Company News – SELF SANITIZING DOOR HANDLE BY UV PHOTOCATALYTIC TECHCNOLOGY

In 2003, SARS spread out in Hong Kong. It infected thousands and killed hundreds here. People noticed that the importance of public health. We knew that many infection can spread out by contact, for example, SARS, MERS, Foot and Mouth Disease and Candida auris. Then, we decided to design door handle to public to prevent those infection to spread out and enhance public hygiene.






The working principle of the product is that a thin advanced photocatalytic coating could effectively decompose bacteria on the surface of a substrate. Since a consistent UV light source is required to activate TiO2 film for disinfection, a custom-designed generator is used to provide stable electricity to light up a UV LED lamp by motion of opening and closing door. Reflections of light could occur inside a transparent glass door handle to activate coating on the outer surface. Then, the door handle can sterilize and clean by itself.




The design is simple and effective. Nowaday, people use chemical cleaning material to clean up public area but it is easy to wipe off and harmful for human body. Our design has high durability and effective. It can clean up itself after using. In the door lock and door handle market, it is unique design because there is no similar products.
