1. Overview UV100 and UV200

2. Why UV-C works best Standard 1 Media, 5 Pleated, Electrostatic, and Electronic Filters may be capable of capturing microorganisms, but they can not kill themUV-C do not capture these microorganisms however it will neutralizesterilize-sanitize: Cold viruses - Influenza Staph -Mold Strep -Fungi CFor the ideal Indoor Air Qualtiy system you should have a combination of high quality filtration to capture and UV-C Lights to kill! 3. UV-C Lights Overview What UV is and why it works! Everyone take a deep breathThis is what you just breathed in: Mites, Spores, Viruses, and Bugs 4. Types of UV Energy UV is measured in nanometers (nm which is one billionth of a meter) There are three classes UV-A (315-400nm) Black Light/Tanning Beds UV-B (280-315nm) Sun Burn/Skin Cancer UV-C (200-280nm) Germicidal DNA Killer 5. History This is not new technology. The use of ultraviolet lights to dates to the early 1900s. If is currently used in: Hospitals Municipal water treatment Mandated in all new Federal building construction 6. Here is what these microorganisms look like under the microscopePneumoniaMold 7. Should the consumer want UV lights? Health Benefits Airborne microorganisms from sneezing and coughing are often responsible for the spread of disease in indoor environments HVAC equipment can actually breed germs, viruses, and allergy causing molds 8. How they operate UV light is generated by an electrical charge through low pressure mercury vapor in a glass tube. Similar to a fluorescent light. The lamps react in the same manner 9. How does UV kill or sterilize? Light penetrates the cell walls causing cell and genetic damage at the DNA level. The affected microbe is neutralized or sterilized making it incapable of reproducing. - Viruses are fragile and easy to kill - Fungi are hardy and difficult to kill 10. What a strand of DNA looks like What is DNA?Bases The UV-C light rearranges the bases the comprise the bands of DNA effectively sterilizing them where they can not reproduce The microbe either dies instantly or within a few short hours. 11. Vocabulary and Definitions Dose dwell time: The amount of time a microbe is exposed to UV light Dependent on how fast (cfm) the air is moving The slow the cfm the longer the dwell time 12. Vocabulary and Definitions Surface Kill: Any particulate or microorganism captured on a surface such as an air coil or filter Airborne Kill: Any particulate or microorganism suspended in the air stream 13. Efficiency to Neutralize and Sterilize The ideal frequency for microbial destruction is 253.7 The Comfort Plus delivers the majority of its output at this frequency The Comfort Plus UV-C light produces from 2 to 5 times more energy to kill the microbes than the competition Intensity and Exposure time determine how quickly a microbe is disabled Comfort Plus UV-C does not produce ozone. 14. Three variables on performance Any change in one of the following three variables impacts the efficacy of the lamp Air Flow Slow cfm is better Temperature 100 F is optimal UV Output The higher the output the greater the kill dosage 15. Air Flow The slower the air flow the longer the dwell time, hence contact with UV light The longer the dwell time the more bugs you can kill Take into account where air is the slowest and temperature has the least impact on lamp performance 16. Temperature The optimum output is at approximately 100 F Temperatures above or below 100 F degrade performance Where do you place the lamp? A variable temperature location? A constant temperature location? 17. UV OutputmicroW/cm2 output36 watt versus 60 watt microW/cm2 output The Comfort Plus UV Light uses a 60 watt double bulb lamp Competition is only 36 watt2000Comfort Plus Well deliver twice the killing power than any 60 watt competitor under identical1000 0 050100Air Temperature150Competition 36 wattoperating parameters 18. How to Apply I asked the question before, where do you put the lamp? There are valid arguments for either supply or return ATTACK THE SOURCE 19. Caution When Applying Near Plastics Important: UV-C will gas off certain plastic polymers if they are not impregnated with UV-C inhibitors. Use caution when applying the lamp around items such as plastic drain pans and pleated media filters. The farther away from the material the less affect the UVC will have on it. 20. Auto-Voltage Sensing Connects to 120 or 240 21. Proper Sizing of the Lamps UV100 is suitable for slab coils applications of 3 tons or less and 1200 cfm or less UV200 is suitable for slab coil, A-Coil, and Return Air Applications
