Q: What will be my electrical cost to run the Calutech "BLUE" 24 hours a day, 7 days a week?
A: Electrical Cost will be approximately $20.00 per year.
(((Your kwh Charge X 0.05 kwh used) X 24 Hours) X 30 Days) X 12 Months Q: Another company selling UV systems uses Cold cathode lamps and said they are much better than Hot cathode lamps which the "BLUE" uses. Your comments?
A: Hot and Cold cathode are the two type of UV lamps available. Cold cathode are normally OZONE producing UV lamps, and start better in cooler temperatures than hot cathode lamps, however in winter months hot cathode lamps start better than cold cathode lamps. So what's the difference? There isn't much difference. In cold temperatures our Hot lamps may take an additional second or two to ignite and light up, but once ON they're doing their job. In hotter temperatures
the same thing happens, but the other way around. What really matters is UV microwatt output and warranty protection which competitors can not compare to. Even more, our replacement lamps are very competitively priced. Q: Does your system produce OZONE?
A: NO! CaluTech uses UV-C @ 253.7 nm Hot Cathode lamps which DO NOT PRODUCE OZONE! (ONLY UV below 240 nm produces Ozone) per the Navy Environmental Health Center! (Click and Read Document) Q: Another company says their UV lamps last for 3 years, yours are only 1 year. Why is yours only 1
year?
A: Others use 3 years as a marketing and sales feature to make you think they have better lamps. We could do this too... but we don't! Our lamps will last for 3 years also, but ALL UV LAMPS lose their ability to produce strong effective UV-C light after about 9,000 hours (12 months of use), which is why we recommend annual changes of the UV lamps. Using the lamps for 3 years means they are not operating at their full capacity anymore. Search the web and you will see that UV-C germicidal bulbs effective strength life is 9,000 hours (12 Months), NOT 3 years! Q: Do I install the "BLUE" unit on the cold air return side, or on the hot side after the blower fan?
A: Either side. The purpose of the product is to sterilize the air, but they also make a great coil cleaner if you have A/C. Installing it at the coils (hot side) means you're cleaning the air and the coils at the same time. Q: Why do some companies say they're unit should only be installed in the cold air return?
A: Because they're not certified for heat, so furnace heat may melt or damage their unit. Our Blue UV model was heat oven tested at CSA labs in Cleveland, Ohio and passed the heat stress, with no change in operational ability. Another reason some companies say cold side only is because they use cold cathode lamps, which can literally
turn off in high heat areas such as furnace heat. They need cold or room temp air to stay on, where hot cathode lamps can operate on either side effortlessly. Q: Will my humidifier and moist humidified air damage the "BLUE" Unit?
A: The Blue was tested for moisture, and is certified for damp locations. The power supply is an outdoor insulated supply. When installing at or near a humidifier the "BLUE" unit should be installed above it, not below it. Water mist will not harm the unit at all, we just don't want water drops from the humidifier itself falling on the unit! Q: What is OxyCat Photocatalytic
Oxidation Snap-Ons and do I have to use it?
A: First, you don't have to use it but.... why not! OxyCat (patent pending) is EXCLUSIVE to Calutech products which allows your UV BLUE system to not only attack living organisms like Viruses and Bacteria, BUT also attack airborne odors and VOCs! Other UV-C systems do not attack VOCs! Using OxyCat makes your "BLUE" Unit a Complete in-duct air purifier! Q: I'm not really sure where to install the "BLUE" Unit, any recommendations?
A: First, see below COMMON INSTALLATION. If you are still wondering about installation print out our
installations recommendations and have a Certified Heating and AC contractor install the unit. They will know! |
