HANDRAIL UV STERILIZATION DEVICE

UV Sterilization Mechanism

• Depending on the wavelength, ultraviolet light can usually be divided into long, medium and short wave ranges.

• It’s the short-wave ultraviolet light that kills bacteria. The sterilization effect is the strongest with the wavelength of 250-275nm (UVC).

• When the handrail is running, the UV light on the sterilization device is used to kill the bacteria on the handrail. Sterilization rate ≥99%

• The sterilization device is concealed on the return side under the handrail to ensure passenger safety.

• Multiple sterilization devices can be installed on the same escalator, based on the rise of the unit.

3. 3-D Drawing

Ultraviolet can be divided into long, medium and short according to the wavelength. The short wave ultraviolet has the bactericidal effect, which is generally 200~275nm and we call it UVC. Among the range, the 250nm~275nm range is the best waveband for sterilization. The principle of the UVC sterilization method is to damage the molecular structure of microbial cell’s (bacteria, virus and other pathogens) DNA and RNA.

1. Note: The specific product parameters should be subject to the drawings. The specifications of this manual are for reference only.

2. The intensity of ultraviolet light decreases with the square of the distance of the LED light source, and because of its weak penetration, it must be close to the material that being processed.

3. The effect of ultraviolet sterilization is related to irradiation time and distance. The sterilization will be better if the irradiation time is longer and the distance is closer.

ANALYSIS & TEST RESULTS

HANDRAIL UV STERILIZATION DEVICE

***According to the length of the handrail at 28m and the running speed at 0.5m/s, one running cycle of the handrail is 56s and the residence time of the irradiation area is 0.2s. Since the cumulative effective sterilization time is 1min, escalator needs to operate in 16800s to achieve the abovementioned sterilization effect, about 4.6 hours (all the above calculations are derived from theoretical data).

UV STERILIZATION MECHANISM

• UV lamp is a kind of light that is invisible to the naked eye. The wavelength of the light wave below 380nm is called UV.

• A wavelength below 380nm is called UV.

• In the natural sunlight, UV-A accounts for about 98.1%, UV-B accounts for 1.1%, and UV-C is almost absent due to absorption by the ozone layer.

***UVC is a C-band ultraviolet light with sterilization effect.

UV Sterilize

Wavelength 240-280nm deep UV rays can destroy the DNA or RNA molecular structure of bacteria and cause bacterial death.

• The irradiation of UVC to microorganisms such as bacteria and viruses will destroy the cell structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) of microorganisms, cause DNA strand breaks, crosslinking of nucleic acids and proteins, and cause death of growth cells and regenerative cells, to achieve the effect of sterilization.

• C-band UV is easily absorbed by the DNA of living organisms, especially UV at 253.7nm.
