Twenty Examples of How It Works
1. How does this ASIET equipment work?
-
Add it directly to any existing heating system.
-
Available as portable stand alone unit.
-
Install directly to most roof top systems
2. How much does it cost to purchase and
maintain?
-
Price is based on the size and condition of area needing treatment.
-
Maintenance consists of periodic cleaning of UVC bulbs and rotating
reactor shields. UVC Bulbs are designed for one year of constant use.
3. Is the equipment harmful to the air
conditioning/heating system?
-
No, adding ASIET Environmental equipment to your existing heating system
disinfects and cleans the airflow as well as the existing air handling system
will improve the systems overall performance.
4. Is this equipment Green Energy?
-
Yes, ASIET SYSTEM cleans up the indoor environment and reduces over all
energy consumption in the process.
-
Reduces amount of energy by eliminating air borne particulates and
contaminants.
-
Less energy to heat or cool air than microbial sized solids in the air.
5. Is

contaminants.
-
Less energy to heat or cool air than microbial sized solids in the air.
6. What harmful VOC’s contaminate are air inside
our homes and business?
-
VOC’s are the most difficult to detect and measure, yet are some of the
most harmful to human and animal health.
-
VOC’s consist of organic particulate as well as airborne chemical spills
-
VOC removal or conversion is equally important to biological and
particulate removal.
-
VOC’s can affect the nervous and immune systems.
-
VOC’s causing loss of productivity, nausea, long-term chronic illness,
cancer or death in some people.
7. What are the most common molds found in sick
buildings?
-
Recent studies have identified Cladosporium, Penicillium, Aspergillus,
and Alternaria to be the most common molds found in problem facilities. Based on
testing preformed by Air Quality Sciences, Inc. Atlanta GA
8.
Why should I concern myself with biological issues?
-
Regardless of weather you realize it or not we are all breathing cleaning
chemicals, pet and human dander as well as decomposing organic matter in our
indoor environments. Conventional filtration systems even HEPA filtration does
nothing to elimination viruses, bacteria, and other pathogens from the air we
breathe.
9.
Are there any health effects?
-
Allergic reactions are the most common health problems associated with
biological pollutants. Symptoms often include watery eyes, runny nose and
sneezing, nasal congestion, itching, coughing, wheezing and difficulty
breathing, headache, dizziness and fatigue. Dust mites have been identified as
the single most important trigger for asthma attacks.
10. Why
do I have mold in my building?
-
Molds and dust mites thrive in areas of high humidity. Mold grows on
organic materials such as paper, textiles, grease, and dirt and soap scum. Mold
spores float throughout the building structure, forming new colonies where they
land. Dust mites thrive on dead human skin cells and in textiles such as
bedding, carpeting, and upholstery. When these textiles are disturbed during
vacuuming, making beds, or walking on carpet, the dust particles become
airborne. Pollen, plant material that enters through windows or on pets and
animal dander also become airborne when disturbed. Infectious diseases caused by
bacteria and viruses are generally passed from person to person through physical
contact, but some circulate through indoor ventilation systems
11. Why
do I have formaldehyde in my building?
-
Formaldehyde is a chemical that is released into the air as a foul odor.
It has a number of useful properties; it's a good preservative and makes an
excellent adhesive. Therefore, it is used widely in the building and furnishings
industries. It is also found in small amounts in some textiles as an
anti-wrinkle agent.
12. I'm
concerned about the biological contaminants in my home or work place, what can I
do to reduce my exposure.
-
By installing ASIET’ equipment in you heating system you can start
eliminating biological contaminants and or pathogens. There are no practical
tests for biological contaminants for use by non-professionals. However there
are signs to watch for. You can sometimes see and smell mold colonies growing on
surfaces. Mold growth should be suspected wherever there are water stains,
standing water or moist surfaces. Although we don’t do air testing we have
names of several firms through out United States we are always happy to share
these firms contact information with any one concerned about their air quality.
13. Why
the best air filters alone are not enough?
-
Air filters, including High Efficiency Particulate Air (HEPA) filters
have been used for many years in heating, ventilating, and air conditioning
(HVAC) systems. Some are very effective in trapping particles like pollen and
dust. Unfortunately they cannot trap minute particles like viruses, most
bacteria, and mold spores that breed in the dark moist interiors of HVAC cooling
coils and drain pans, which are located downstream of filters. There is also a
problem with fungal spores growing and multiplying in damp HEPA filter material.
When this happens, the filter can actually increase the number of Mycotoxins
spores in the room or the building. Ultraviolet germicidal devices radiate
powerful UVC light onto the coils and drain pans inside the air-conditioning
system where mold and other odor and disease causing organisms breed. The UVC
light inactivates and gradually vaporizes this microbial growth, removing it
from the air, thus accomplishing what the air filter cannot do.
14.
What about ultraviolet light alone?
-
Installing UVC lights alone is not the best solution due to short
(exposure) dwell time and air speeds in air systems. UVC bulbs with out reactor
shields need to be in very close proximity to surface needing cleaning for an
extended length of time.
15.
What is UVC?
-
Ultraviolet light represents a portion of the sun's electromagnetic
spectrum. It is the wavelength band immediately beyond the violet end of visible
light. The UV range of the spectrum is characterized by wavelengths between 100
and 400 nanometers (nm). 15.
16. How
often do the UVC lights need to be changed?
-
Cross Rode’s Technology recommends cleaning your bulbs every time you
rotate reactor shields. Bulb life varies between 9,000 to 12,000 hours which is
about one year of constant use.
17. Is
ozone an air purifier or a contaminant and pollutant?
-
Ozone is being marketed by some as an air purifier, often in conjunction
with UVC. It is true that UVC will produce ozone at low frequencies. According
to the U.S. Food and Drug Administration: "Ozone, to be effective as a
bactericide or deodorizer, must be present in concentrations far greater than
that which can be safely tolerated by man or other animals." According to the
U.S. Environmental Protection Agency, ozone is a toxic gas with vastly different
chemical and toxicological properties than oxygen. When inhaled it can damage
the lungs and relatively low amounts can cause chest pain, coughing, shortness
of breathe, and throat irritation. Ozone has been used effectively for years to
clean wastewater. In water containing organic material, ozone is used up rapidly
-- before it reaches the air.
18. Why
don’t the UVC bulbs in our equipment produce ozone?
-
All of the manufactures of UVC bulbs used by Air Scrubbers International
Environmental Technologies are designed to block the Ozone from any and all
bulbs we allow in any equipment we manufacture.
19. How
does the combination of the proper UVC bulbs and custom coated Reactor shields.
-
ASIET’S photo catalytic oxidation technology is both superior in
efficiency and effectiveness to existing filtration or UVC alone. Some other
processes utilize ozone, UV, activated charcoal, HEPA, electrostatic, or
ionization filters. ASIET technology combines the best of these processes -
rotatable reactor shields and UV irradiation with catalytic filters to truly
cleanse, not just filter, the air.
-
HEPA filters remove smaller particles than do the rotatable shields,
however, HEPA filters require more energy to operate and have no germicidal
action.
-
Activated charcoal removes odor by adsorption and need frequent changes
but has no germicidal action.
-
Ionization chambers place a charge on particles causing them to cling
together on filters, air duct components, and walls but have no germicidal
action.
-
UV lights have a germicidal action and have cured sick building syndrome.
However, UV light alone is not as effective as is the combination of UV and
metal oxides such as TiO2.
20.
What scientific proof is there?
-
Texas Tech University's Department of Biological Sciences evaluated UVC
assisted reactor powered equipment for germicidal effectiveness in laboratory
studies. The equipment tested was a special research machine that contained UV-C
germicidal lamps and photo catalytic reactors. It has long been established that
irradiation from UV-C lamps kills bacteria by direct exposure. Equipment was
developed to test the hypothesis that E. coli exposed to an air stream treated
with UV-C light and photo catalytic reactors would be killed at a faster rate
than would E. coli exposed to an air stream not treated with photo catalytic
reactors. E. coli in both test and control conditions were maintained in the
dark. The special test machine developed for Texas Tech exposed an air stream to
photo catalytic reactors irradiated with UV-C light; then the air stream moved
through a light-blocking filter into a dark (no light present) chamber. This
stream of treated air was on the experimental side of the machine. The control
side had a stream of air similar in volume and flow to that on the experimental
side. The control side contained no photo catalytic reactors.
-
Cultures of E. coli were established on Petri dish plates with agar
media. E. coli colonies on the agar plates were too numerous to count (TNTC) at
the beginning of the test. Eighteen plates with E. coli TNTC were exposed, in
groups of three, to the treated airflow in the dark chamber for 10, 20, 30, 40,
50, and 60 minutes and then removed to count surviving colonies of E. coli.
