You can install the lights right above the coil, so UV lights shine on it continuously to prevent the growth of mold. Ductwork UV Lights or Air Germicidal HVAC lights are meant to kill airborne allergens and pollutants making their way through your return vents.
In every case, does a UV light go in the supply or return?
Ultraviolet lamps can be easily added to an existing forced air system. Lamps can be installed either in the main supply or return duct of a central heating or air system. The best installation location for a UV lamp is downstream of the air conditioning coils on the supply side of the heating/cooling system.
Apart from this, are UV furnace lights worth it? With the right conditions and proper installation, UV lights can be very effective at killing viruses, mold, and bacteria. The two working together can make your home or office building a much healthier place.
Anyhoo, how do you install a UV light in an air handler?
Does UV light in HVAC system work?
Germicidal or UV lights for HVAC systems are used to kill the DNA of germs, viruses, mold spores, bacteria and fungi as they pass through the air handler system. A strategically placed UV light is very effective at killing close to one hundred percent of these harmful pollutants.
In short, the use of these lights is not hazardous inside the system and any metallic odors you smell may be the result of the production of ozone gas by the UV-C lights.
If the lamp wattage is divided by the square footage of the coil surface (80/10.76) = 7.43, it's seen that about 7.5 lamp watts per square foot of coil surface area will meet the recommendations. This then provides a simplified way to properly size future UV installs for most any coil, large or small.
Not only does it use UV technology, it has two-stages of air filtration that helps remove contaminants from the air. It can destroy mold and pollen, as well as many of the biological pollutants in your home air.
Ultraviolet germicidal irradiation (UVGI) Ultraviolet germicidal irradiation, or UVGI, uses ultraviolet light to kill or inactivate microorganisms. As UV light from a UV lamp comes into contact with cells, the UV light breaks down the organism's DNA, disallowing it from replicating.
Currently, most of these lamps operate at 300 to 600 watts per inch with some newer systems using lamps that generate up to 1000 watts per inch. So a 30 inch UV bulb may be capable of an output of 30,000 watts.
The REME Halo-LED has superior energy saving by cycling on and off with your HVAC system, destroys VOC's (Volatile organic compounds) 2x's faster than typical UV air purifiers, and has a much longer life than a typical UV light.
We recommend changing your UV germicidal light at least every 12 months to maintain a clean, healthy environment. Lamp life is generally 6 to 12 months for most brands. You can expect to spend $10 to $60 per year for new lamps depending on whether you have a 1 lamp or 2 lamp system in place.
If you or someone in your home has respiratory issues, then investing in a top-notch UV filtration system for your HVAC system is absolutely worth it. UV filtration systems can inactivate a variety of viruses, bacteria and other harmful microbes like mold.
Your eyes can be damaged from ultraviolet rays. In particular, UV-A and UV-B rays from the sun can cause short- and long-term damage to your eyes and affect your vision. Although the sun also emits UV-C radiation, those rays are absorbed by the ozone layer and don't damage your eyes.
However, with the use of these devices it has been often noticed that there is a residual odor after disinfection, otherwise known as volatile organic compounds (VOCs). This odor has been described as a sulfuric smell similar to rotten eggs, garlic, or burning hair.
High-temperature filaments emit some energy in the UV region. Small amounts of other elements can be mixed into the quartz, so that the doped quartz blocks harmful UV radiation. Because the halogen lamp operates at very high temperatures, it can pose fire and burn hazards.
Features. 18-32 VAC , Non-Ozone quartz 254 NM UV-C lamp for airborne germicidal disinfection. The technology of the APCO is the carbon cells attracting and holding odors and microbes then catalyzing them by exposure to the UV light. APCO is effective in the reductionof toxic VOC's and other odors.
The ultraviolet lamp usually consists of an electric discharge lamp with material that yields radiations at the desired wavelength. Ultraviolet lamps are usually housed in quartz or special glass that transmits ultraviolet radiation more readily than ordinary glass.
Choose Between a Clarifier or Sterilizer As a rule of thumb, use 10W of UV light per 1000 gallons for 'clarification', and 30 watts of UV light per 1000 gallons for 'sterilization'. As a sterilizer, the unit will eliminate green water entirely, no matter what type of pond you operate.
Typically, a UV lamp being used primarily to disinfect the air circulating through a home or small office should be replaced every 9000 hours or approximately every 12 months.
How safe are UV purifiers? It's questionable. The biggest issue with UV purifiers is that they emit varying levels of ozone. Even very small amounts of ozone in the air may result in chest pain, coughing, shortness of breath, and throat irritation.
UV lamps reduce the presence of mold, bacteria, VOCs, odors, and most other allergens from your AC system. This brings down the instances of cold, flu, asthma attacks, and other allergic reactions.
UV-C Light Air purifiers that use ultraviolet light to kill microorganisms (also known as UVGI, ultraviolet germicidal irradiation) only work against certain species. ... Therefore, UV-C air purifiers are not ozone-free. Not only do they produce ozone, they are not very effective in a residential setting.
