- 1. Output
ratings claims.
- Make your
own comparison sheet, don't trust the one's that you'll
find on a variety of web sites, some give improper information or
fail to include appropriate competitive equipment.
-
- 2. Output
and coverage ratings
- Make sure any ozone generator you
consider purchasing has a "mg/hr"
or a "g/hr" output rating. Any reputable ozone
generator company will have had there ozone generators tested on a
photometer. Here at Crystal Air we use a Dassibi 1008 PC ozone
tester that costs about $8,000 - $12,000, the same brand and model
used by most government agencies. Ratings in "ppm" are a
simple concentration rating and do not tell anything about the
overall production.
-
- Be very careful about purchasing any
ozone generator that claims:
- A. "ABSOLUTELY
NO CLEANING OR MAINTENANCE REQUIRED". We have tested
several different brands and models as well as speaking with several
of the sellers, they are either disposable or you MUST purchase
costly replacement plates, UV tubes, or other parts instead of
cleaning. These replicable, unclean able plates or tubes cause the
ozone production to slowly reduce over time until they finally stop
working. Crystal Air ozone generators are designed to last for years
to come and carry a 4 year warranty to prove it. When maintained
properly the plates will last up to 4 years maintaining a steady
amount of ozone production, the unit itself will last much longer.
- B. or "NEW
PATENTED DESIGN", we have yet to truly see a
"new" ozone generator plate design, they are simply a
different ground electrode shape, mounting design, etc. A
plate by any other name is still a plate.
- -Some companies even try to fool you
into thinking that the patent covers nitrogen oxide and states that
they are nitrogen oxide free. We have researched all such patents
that we have been able to find. WE HAVE NOT
FOUND ANY MENTION IN ANY OF THEM UNLESS THEY ARE USING OXYGEN.
-
- 4. Low
grade disposable plastic ozone generators
- Be very careful of the " small
all plastic ozone generators"
that are for sale on various web sites. Most are a very low grade,
very low output, disposable generator. We regularly receive orders
from customers who complain that they bought a small plastic ozone
generator only to find out that it is pretty much useless except for
in the car. Crystal Air ozone generator chassis are built using high
grade stainless steel, the outer cabinet on the PRO series is made
from high impact extruded PVC that will withstand a lot of abuse.
-
- 5. Built
in ozone controllers
- Don't waste your money purchasing
ozone generators that contain "ozone
controllers", they all use the HMOS sensor
technology that stops sensing ozone as soon as they are exposed to
contamination such as cigarette smoke. When this happens the ozone
generator will continue running and reach an over toxic
concentration of ozone.
-
- 6. Zero
nitrogen oxide claims
- Do not believe claims about corona
discharge ozone generators that claim "zero" or "no
nitrogen oxides". ALL CORONA DISCHARGE
OZONE GENERATORS CREATE A SMALL AMOUNT OF NITROGEN OXIDES"
unless they use pure oxygen for feed gas and have absolutely no
steel of any kind in the generation chamber. The amount produced is
negligible, approximately 1/100 of the amount of ozone being
produced. In an ozonated area that is safe to occupy (>0.04 ppm)
the nitrogen oxide level would be around 0.0004, well below the safe
level.
-
- Some companies have used a testing
method that does not work, Draeger gas
testing tubes and Matheson gas detector tubes for nitrogen are not
usable in an ozone environment. Both companies state in
their instructions that they will not give an accurate reading in an
ozone environment. Draeger say's that the nitrogen oxide tests are
"not compatible with an ozone environment" and
Matheson states that "the stained layer is decolourized by
ozone"
-
- We have tested our equipment with
the Matheson gas testers and came up with 0 nitrogen oxides, However
we know that, THE TESTS HAVE ABSOLUTELY NO
MEANING WHEN DONE IN THE PRESENCE OF OZONE so we do not
claim zero.
-
- The Draeger and Matheson gas test
tubes use a small glass tube that contains cotton type batting
inside that is soaked in a special chemical regent. The tubes are
inserted into a special pump that draws a calibrated amount of air
through it. The regent discolours up the length of the tube which is
marked with concentrations. The problem is that as soon as the
regent changes color it is bleached or
" discoloured" by the ozone and shows no
reading, thus zero nitrogen oxide readings are obtained.
-
- 7. New
type of air claims
- Some companies marketing ozone
generators are claiming to have invented a
new type of air, such as "a higher form of
oxygen" and have given it there own name. Ozone is ozone no
matter what name you stick to it.
- - one claims to make more 04,
05, 06, 07, etc than 03.
They fail to mention in there information that it is a well known
fact in the ozone industry that this is a characteristic of corona
discharge.
-
- Some companies have tried to copy
our PRO series ozone generators, they use a cabinet that
looks similar. The problem is that the cabinets are a much thinner
plastic or aluminium and the components are inferior, usually
imported from Taiwan or? Just checkout the warranty, this will show
if they actually stand behind the quality of the product they are
selling.
-
- 9. How
long have they been in business
- Check how long they have been in
business. Crystal Air has been in Business
since 1993 (10 years). If they haven't been in business
for at least 5 years then it is risky to purchase from them unless
the equipment comes from a reputable ozone supplier, there is a very
good chance that they will go out of business before they reach 5
years and then you will have trouble getting support or replacement
parts. Remember, it is a well known fact that most small businesses
do not last 5 years.
-
- 10.
Where are they manufactured?
- Be sure to ask where they were
built. All Crystal Air ozone generators are designed and built in
Canada, this means that if you have a warranty problem there will be
absolutely no problem getting I t repaired. BE
VERY CAREFUL ABOUT BUYING AN OZONE GENERATOR THAT IS BUILT IN AN
OVERSEAS COUNTRY. Warranty repairs are hard to get and
time consuming if you are able to get it repaired at all.
-
- 11.
Ozone generator construction
- All Crystal Air ozone generators are
built to the highest quality standards, using the highest quality
materials. We use stainless steel and PVC,
the only cabinetry materials that withstand ozone and do
not corrode. Also make sure that that unit is not made entirely of
PVC. PVC will not withstand the high voltage that is used in ozone
production, ALL COMPONENTS MUST BE MOUNTED
ON A STAINLESS STEEL BASE.
