About Ozone and Hydroxyl
Ozone is the second most powerful oxidant in the world, saturates hard-to-reach spaces and leaves no chemical
residue, which is why it is useful for cleaning applications such as mold eradication and odor removal. It also
destroys pathogens such as bacteria and viruses on surfaces making it an excellent disinfectant. Ozone contains
three atoms of oxygen rather than the two in normal air. This extra oxygen atom will quickly combine with or "oxidize"
harmful compounds, causing them to break down. Ozone used in high enough concentrations to kill odors can also
damage the respiratory tissues in humans and animals, and also tissues in plants, requiring it to be used in unoccupied
areas only where pets and plants are removed. Ozone naturally decays back into normal oxygen within a few hours
depending on the temperature.
About Ultraviolet Light Ozone Generators
There are two ways to make ozone: Ultraviolet Light and Corona Discharge. Both methods occur in nature. Most
of the planet's ozone is generated in the upper stratosphere from high-energy solar radiation (Ultraviolet Light)
breaking apart oxygen molecules which temporarily re-form into groups of 3 (trioxide, a.k.a ozone). Also called
the ozone layer, this gas shields the earth's surface from the sun's most dangerous ultraviolet light and makes
the sky appear blue.
Ultraviolet (UV) Light
Ozone Generators use low pressure UV lamps that generate multi wavelength UV light with two peaks, one at the
254-nm light band and another at 185-nm. The 185-nm light produces ozone through photolysis of oxygen molecules,
while the 254-nm light photolyzes ozone back into oxygen, which works against the ozone production process. This
unfortunate second peak is why low pressure UV lamps produce much less net ozone than Corona Discharge (CD) Ozone
Generators when operating in cool, dry environments. However, UV light ozone generators produce ozone at a near
constant rate, even when the environment is warm and wet, making them much better in hot, humid conditions. Plus
they do not generate byproducts from nitrogen in the air.
Ultraviolet Light Ozone Generators, while less powerful and more expensive than Corona Discharge units, can remove
strong odors and sterilize viruses and microorganisms under harsh environmental conditions such as high heat and
humidity. Our premium ultraviolet light ozone generators are innovative, versatile and can generate from 1,500
to 10,000 mg/hr of ozone starting at $499. Our smallest compact model weighs only 7 pounds, yet is nearly as powerful
as some competitor corona discharge units. Our price point averages 30 to 40 percent lower than similar output
ultraviolet ozone generators from competitors. Simply put, we sell serious ultraviolet ozone generators to customers
who want high-performing products at the lowest prices. Plus, we stand behind every product we sell with a money-back
About Corona Discharge Ozone Generators
In the lower atmosphere, ozone is generated by static electricity (Corona Discharge) during lightening strikes
which also break apart oxygen molecules that temporarily reform as ozone before reverting back to normal oxygen.
Corona discharge is a static shock that can be generated using electricity. The first man-made ozone machine used
two glass tubes wrapped in tin, one inside of the other so that air could circulate in the space between them.
When the surrounding conductor was energized with high voltage it ionized the air near the conductor surface resulting
in an electrical discharge that produced ozone. Corona discharge is the most efficient way to produce a large volume
of ozone from cool, dry ambient air.
Corona Discharge (CD) Ozone
Generators use discharge plates with electrodes and an insulating, dielectric material that supports an electrostatic
field without heating up excessively. A transformer is used to convert standard low frequency household power into
high frequency, high voltage that can produce large quantities of ozone from the ambient air that passes near the
plates. Ozone plate technology and transformer design have improved significantly over the past few years. Compact,
double-sided corona discharge plates can produce 8 to 16 grams of ozone per hour from a single transformer, allowing
a small machine to quickly saturate an area with ozone. However, cool dry air is required for maximum output, and
high humidity can result in undesirable corrosion from nitrogen compounds that accumulate on the plates. When the
environment can be controlled corona discharge ozone generators are the most efficient choice.
High-output Corona Discharge Ozone Machines remove strong odors and sterilize bacteria, viruses and mold spores
in minutes! Our portable ozone generators are the industry's most powerful and durable units, generating significantly
more ozone than the over-priced "metal box" machines advertised everywhere. Whether it's for a home,
vehicle or a business, when you have serious odor problems you'll want a BoiE to do the job quickly and completely!
Simply put, we sell serious commercial-grade ozone generators to consumers who want high-performing products that
do the job fast at the best price point. Plus, we stand behind every product we sell with a money-back guarantee
and great customer service!
Hydroxyls are formed in nature by the reaction of UV light from the sun disassembling water vapor (H20) into
hydroxyl radicals (*OH) which has a single hydrogen and single oxygen atom. Atmospheric hydroxyl radicals neutralize
pollutants when they make contact similar to ozone, except hydroxyls take an atom away rather than giving one up.
Hydroxyl radicals react over a million times faster than ozone and with many more compounds. However, an average
life of less than a second makes it impossible to build up high concentrations like ozone. Hydroxyl generators
require powerful fans to move large volumes of air and quickly deliver hydroxyls to large areas where they can
start chain reactions with pollutants that will spread throughout a space.
Hydroxyl generators are widely used by water and fire damage restoration companies because the hydroxyl radicals
generated are non-toxic to humans and work exceptionally well in hot, humid environments (conditions adverse to
ozone) to remove the same contaminants as ozone along with additional compounds, although over a considerably longer
period of time. Where a two-hour ozone treatment would be sufficient, a hydroxyl generator might take three times
as long to achieve similar results, but the area can remain occupied and the hydroxyls do not react with certain
adhesives and rubber that ozone can affect. A disadvantage is that multiple hydroxyl generators are often needed
to complete the job.
About Ozone-Free Hydroxyl Generators
There are two ways
to generate hydroxyls: (1) ozone-producing (multiple wavelength) UV lights and (2) ozone-free UV lights along with
a nano catalyst. Multiple wavelength hydroxyl generation such as the Odorox Boss® is essentially an ultraviolet
ozone generator that has been coupled with a large fan. Also called direct hydroxyl production (DHP), the advantage
is that hydroxyls are created in the air around the lights so more reactions can occur. The disadvantage is that
ozone is created and adequate ventilation is needed if the area is occupied.
Ozone-free hydroxyl generators (what we sell) use Photocatalytic Oxidation (PCO) technology developed by NASA to
purify air onboard the International Space Station without harming the occupants. PCO uses safe, ozone-free ultraviolet
black light that shines on a catalyst where hydroxyls form when there is sufficient water vapor in the air. When
pollutants enter the machine and react with hydroxyls, they form peroxy-free radicals which quickly react with
VOCs and inorganic gases in cascading reactions that follow the air stream outside the generator as contaminants
are broken down into carbon dioxide and water. PCO technology requires about 60 percent humidity to work efficiently,
which is why we include an accelerator to supply ultrasonic water vapor to the unit when needed.
Hydroxyl generators are used in the restoration industry mainly in high-humidity environments where corona discharge
ozone is less effective, especially after floods or fires have been extinguished and materials are very wet. Hydroxyl
generators are often run at the site in the days before serious work starts on a restoration project to help purify
the air and prevent mold from taking hold. Hydroxyl radicals react with over 5,000 compounds and will break apart
odors from fire and smoke, category 2 & 3 water losses, chemical fumes, fuel oil, VOCs, trauma, etc. without
damaging sensitive contents that concentrated ozone might.
