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.
How do you size a UV light?
Choose Between a Clarifier or Sterilizer The main difference between the two is the strength of the UV light compared to the amount of water in your pond. 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’.
Does UV light damage HVAC?
Direct exposure to the UV-C used in HVAC systems is hazardous, particularly to the skin and eyes. Eye damage can be considerable and sometimes permanent, so careful handling and installation by a qualified technician is an absolute must.
How do you determine the square footage that one germicidal UV-C lamp will cover?
Q: How do you determine the square footage that one germicidal UVC lamp will cover? This is determined by the wattage of the lamp. Example: A 15-watt lamp will cover approximately 100 square feet; a 30-watt lamp will cover approximately 200 square feet.
Are HVAC UV lights worth it?
UV light in HVAC units can be most effective in killing mold and mildew. Contact with mold can be dangerous for your unit. In addition, it can also be bad for your indoor air quality and even cause allergies in some people.
What size UV light do I need for my house?
E. Coli, Giardia, and Cryptosporidium typically require a UV dose of 10 mJ/cm2 to become inactivated. The typical whole-house UV system has flow rates of 30 mJ/cm2, which is sufficient for most residential applications.
What size UV sterilizer do I need?
Bulb wattage is the most important factor to consider when purchasing a UV sterilizer, but it’s not the only one. The right flow rate is also essential. As a rule of thumb, you need 10 watts for every 75 gallons of salt water. For fresh water, 10 watts per 150 gallons of water volume works well.
Where do you put UV light on furnace?
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.
How long do AC UV lights Last?
It is imperative that UV-C lamps are replaced on a regular basis. The germicidal UV-C lamps have a useful average life of 5,000 to 9,000 hours. Useful life means that during this time the lamp is operating at an optimal output level for neutralizing mold, fungus, bacteria and viruses.
How do you calculate UV?
How is the UV Index Calculated? Unlike some countries’ indices, the US UV Index is not based upon surface observations. Rather, it is computed using forecasted ozone levels, a computer model that relates ozone levels to UV incidence on the ground, forecasted cloud amounts, and the elevation of the forecast cities.
How long should you run a UV sterilizer?
An aquarium UV steriliser should be switched on and running for 24 hours per day, every day. Exceptions would be setting the tank up before there are any fish in it, adding beneficial bacteria to the water, as UV light kills bacteria, or if you are using a medication that stipulates that UVs should be turned off.
Can you install UV light in return duct?
Depending on your needs and the system you choose, you may install the UV lights directly in the air handler. In addition to the air handler, you may choose to install them in the air return or in strategic areas throughout the ductwork. UV lights can significantly reduce health hazards in an indoor environment.
How often should you replace a UV bulb?
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.
Which is better ionizer or UV?
UV-C light is the clear winner when compared to Bipolar Ionization. UV-C disinfects surfaces and air, provides much quicker disinfection, and is backed by significant scientific research. Bipolar ionization is less effective, lacks validated research, and the technology is being questioned over false claims of safety.
What size UV sterilizer do I need for a 75 gallon tank?
UV Sterilizer Selection Guide UV Bulb (Watts) Maximum Flow Rate for Controlling: Aquarium Size 8 120 gph under 75 gallons 15 230 gph 75 gallons 18 300 gph 100 gallons 25 475 gph 150 gallons.
Is a UV water filter worth it?
Overall, UV water treatment is an outstanding way to meet your families needs for water purification. It has been proven to be one of the most reliable, cost-effective methods for disinfecting water and is applicable in both point-of-use and whole-house water treatment applications.
