Corona Discharge ozone generators produce far more ozone than comparably sized UV ozone generators. The DELZONE ECLIPSE line of CD ozone generators produce up to 5 times the concentration of ozone produced by a UV generator. These Eclipse units produce ozone concentrations reaching 1,350 ppm, while UV generators typically top at about 550 ppm. DEL Ozone EclipseT Corona Discharge Ozone Generators are designed for simple and reliable operation. The EclipseT line consists of three models: the Eclipse-1, Eclipse-2, and Eclipse-4 are designed for use on pools up to 7,000 / 25,000 gallons, 15,000 / 50,000 gallons, and 25,000 / 100,000 gallons, respectively.
