The use of ozone for aquariums, zoos and hatcheries is accepted worldwide. Ozone destroys bacteria, inactivates viruses, and oxidizes organics, aiding filtration. Water is clean and clear without harm or irritation to animals.

"Our polar bears are having a wide-eyed great time in their pool since it has been purified with a DELZONE CD ozone system. Our viewing audience loves the crystal clear water for underwater viewing and are happy these animals are not exposed to harsh chemicals. We highly recommend DEL CD ozone systems."
Steve Worley, Owner-Worley Construction Management, San Diego Zoo, CA.

DEL's Corona Discharge ozone generators are designed to meet unique and custom requirements for individual applications. DEL engineers are experienced at designing specialized components to ensure optimum performance. This creates an approach to water purification that provides facility operators with an automated, low maintenance system.

DELZONE CD Standard Features:

• 2 - 500 grams per hour ozone output available
  
• UL and NSF listed for safety and performance certification
  
• Powder-coated NEMA 3R compliant enclosures
  
• Fully integrated computer control system (PLC) for complete system operation and monitoring of fault controls with visual diagnostic LED's
  
• On-board ORP controller(s) for automatic start-up and shut-down
  
• Water back-flow detection/prevention, interfaced to PLC for automatic shutdown and high voltage lock-out
  
• Self-contained oxygen concentrator units produce oxygen at greater than 85% purity and less than -60 degrees C dew point. Concentrated oxygen feed-gas enables ozone generation at 2-6% (by weight) concentration at 80% lower flow rates than air-fed systems. This eliminates nitric acid build-up, requires smaller overall injection systems, and provides greater dissolution of ozone in water
