VUV Ozone Generator | Corona Discharge Ozone Generator |
---|---|
Constant ozone output, predictable water quality | Erratic ozone output, unpredictable water quality |
Low voltage 50 volt arc | High voltage 10,000 volt arc, hazardous |
Operable with partial system failure, helps prevent down time | Inoperable with partial system failure, increases probability of down time |
Lower concentration per volume of air, more readily absorbed into water | Higher concentration per volume of air, requires contact chamber and off-gas destruction chamber to be effective and safe |
Multiple injection points possible | Single injection points only |
Can be operated without circulation system | Operates only with circulation system, requires filtration run to inject ozone |
Pure ozone production, free of byproducts | Produces nitric acid in generator and pool water, potential damage to equipment |
No electrical noise | Generates electromagnetic radiation, may disturb radio/TV reception |
Replaceable lamps / compressor | Replaceable corona element, dryer, etc. |
Much lower failure rate than any corona discharge ozone system | Higher failure rate due to more complicated equipment and higher voltage |
Prozone has only ozone system UL listed as a pool product | All other ozone systems are UL listed as appliances to be kept a certain distance from the pool water. |
