Home » Interpreting Far UVC 222nm Device Parameters: A Practical Guide

In the previous post, we mentioned several factors that we, as consumers, should consider when purchasing the Far UVC 222, such as the mounting method, the coverage area, the effectiveness of the #faruvc product, the degree of use, and so on. This time, we will share with you how to understand Far UVC222 in more detail from the perspective of parameters.

The common parameters of Far UVC 222 equipment on the market are

Light source, Input voltage, mode, power consumption, Weight, Dimensions, Operating temperature, lifespan, Output, and so on. Below is a detailed explanation of these parameters:

Light source: Light source refers to the type of lamp used in the device, Far UVC 222nm devices usually use low-pressure mercury lamps and LEDs as the light source because of their excellent 222nm wavelength light emission properties. Our product utilizes a third light source type available on the market, the excimer lamp. The advantages and disadvantages of these three light sources are as follows:

  • Low-pressure mercury lamps.

Pros: high UV output, good sterilization effect; low cost.

Cons: short service life, generally 2-3 years need to be replaced; mercury-containing substances, replacement need to be properly disposed of lamps; relatively large size.

  • UVC LED.

Pros: Long service life, generally 3-5 years; small size, can be designed for more lightweight products; mercury-free, more environmentally friendly.

Cons: 222nm UV output intensity is relatively lower than that of low-pressure mercury lamps; higher cost.

  • Excimer UVC Lamp.

Pros: 222nm UV output intensity is high, similar to low-pressure mercury lamps; long service life, at least 3-5 years, the longest can reach more than 10 years;

Cons: technical difficulties, the highest price; low market penetration, and capacity constraints.

Input voltage: Input voltage refers to the type of power supply applicable to the device, usually 110-240V AC. This ensures that the equipment can be used in different countries/regions. In the United States, the maximum voltage is 277V, which you also need to pay attention to when choosing products.

Output: Output refers to the UV intensity of the device, generally measured in μW/cm2. The higher the value, the better the killing effect. It should be noted that the maximum exposure dose of the day, the latest ACGIH requirements, increased the Threshold Limit Values for the amount of 222nm Far UV exposure from 23 mJ/cm² to 161 mJ/cm² for the eyes and 479 mJ/cm² for the eyes. The formula for converting μW/cm2 to mj/cm2 is mj/cm2= μW/cm2* seconds /1000.

Mode: Mode refers to the working mode of the device, at present, it is mainly set by the major manufacturers, and there are two main modes: manual mode and automatic mode. In automatic mode, the device will be switched on and off according to the preset time.

Power consumption: power consumption refers to the power consumption of the device when working, generally between 20-100W. Low power consumption means low running costs. Please pay special attention to this parameter if your local electricity cost is expensive.

Weight: The mass refers to the mass of the device itself, generally the product of separate UVC 222nm killing function is not more than 5kg, which is easy to install and move. Some lighting and UVC222nm combination of products may be a little heavier.

Dimensions: Dimensions refer to the size of the device so that it can be easily adapted to different places.

Operating temperature: Operating temperature refers to the temperature range of the device, usually 0-40°C.

Lifespan: Lifespan refers to the number of years the light source can be used.

Understanding these main parameters can help you choose the best performance of the equipment to achieve the desired results. Please let us know if you have any further questions.
