Fitting seamlessly into existing plumbing with a minimum space requirement, the DEL Ozone CPS-8015 and 8025 skid-mounted fully assembled recirculating ozone systems produce ozone at 15 and 25 grams/hour, respectively, at 2.5-4% by weight. All systems have configurable feed-gas options (integrated oxygen concentrator system is standard), multiple safety features, self-diagnostic switching and robust construction. Variable ozone output control is standard on both models.
