What Is A Germicidal Lamp?
|
UV-C light is considered germicidal because it will deactivate the DNA of viruses, bacteria, and other pathogens which means they are stopped from multiplying and causing disease. A covalent bond between bases is formed within the DNA so the UV-C is able to destroy the nucleic acid of microorganisms. These bonds stop the DNA from being able to replicate so the virus or bacteria can't be reproduced. The minute it tries to reproduce it dies. There are many benefits to using germicidal ultraviolet technology. The fact that it's non chemical is a big bonus. No reactions to chemical, no inhalation of unpleasant smells, no messy applications, and it's very affordable. The ultraviolet purifiers use germicidal lamps that calculate the dosage of ultraviolet that needs to be produced. It's usually around 16,000 to 20,000 microwatt seconds per square centimeter. The principle behind the ultraviolet purifiers is based on intensity and time so you need to be certain the model you choose uses both in its application. I bet you're wondering what germicidal lamps would be used for. There are many applications. Schools, hotels, hatcheries, nurseries, aquariums all use them. They are common to drinking water systems, swimming pools, well water, cisterns, and hot tubs. The lamps are also used in food processing applications such as breweries, wineries, soft drink and bottling facilities, and dairy processing. Pharmaceutical laboratories, hospitals, clinics, pathology labs, kidney dialysis, and even maternity and delivery wards use germicidal lamps. There are several other industrial applications as well. There are several different types of germicidal lamps on the market. It's important that you choose one that's appropriate for the task at hand. The Slimline lamps start instantly and use a coil filament on each end. The life of the lamp is affected by the number of starts and the life of the electrodes. These lamps are a good choice for water sterilization, air purification or other tasks that require an intense ultraviolet treatment. Preheat lamps have a preheat start circuit that requires 4 electrical connections with a slight delay to start the lamp. It uses a compact ballast that's relatively economical. This lamp is very complex and is not quite as reliable as the Slimline but serves its purpose very well. Cold cathode lamps start instantly and use a large cylinder cathode rather than the traditional tungsten filament. This lamp isn't affected by frequent starts and it's got a very long life expectancy. It is also well known for its ability to maintain a consistently high ultraviolet transmission throughout its life. It is a very good choice for disinfection of all types including air and occupied surfaces. The ozone lamps are an extremely reactive form of oxygen and a great choice for water purification. They are also used as deodorizers and cleaning agents. Because human exposure to ozone must be limited the applications of the ozone lamps are limited but it certainly does have some excellent uses within its restrictions. If you want to stop bacteria, viruses, and bugs in their tracks a germicidal lamp is what you need to provide cost effective and efficient protection. Joanne is an author of Decorz.com.
