Class-Leading Spa Ozone Sanitation by DEL
More DEL Ozone spa ozonators have been factory installed in portable spas and hot tubs in the past 10 years than any other manufacturer. There’s a good reason: DEL Ozone engineering continues to lead the market for spa sanitation effectiveness, reliability and cost.
If you own a spa or hot tub made in the U.S. or Canada in the last 10 years, there’s a good chance you already own a DEL spa ozone generator. If your spa or hot tub is more than 3 years old, it may be time to replace the ozonator. Visit DEL's spa website if you think you may need a replacement spa ozonator.
DEL Innovation in Spa Ozonators
DEL pioneered the corona discharge (CD) spa ozone generator with the chip-based CDS-16 which has been installed in spas by manufacturers since 1998. This little powerhouse and its sibling, the dual voltage Spa Eclipse, brought the reliability and simplicity of maintenance of CD ozone to the portable spa industry, helping spa manufacturers provide the pleasing product buyers wanted.
More recently DEL produced the MCD-50 for larger spas and hot tubs. This unit uses a glass chamber in the ozone generator that is more corrosion resistant and lasts longer than the CDS-16, up to 5 years in normal use. The MCD-50 can sanitize hot tubs up to 1,000 gallons.
Today, DEL continues to push the envelope of spa sanitation with continuous research, design innovation and testing. Products in the testing lab today promise to drive the performance up and the costs down. DEL continues to improve the cost effectiveness of spa ozone sanitation.
Replacement Spa Ozonators
One of DEL’s long standing corporate commitments is to customer service at all levels. Recognizing that spa ozonators wear out, DEL makes replacement ozone generators and ozone test kits available to spa maintenance technicians and spa owners through a carefully chosen network of dealers and distributors.
DEL Spa Ozonators Improve the Quality of Life
Like all DEL’s Advanced Sanitation Solutions, the spa ozone generators help spa owners to keep the clean, fresh water that makes the spa experience so desirable. Natural, powerful ozone with its eco-friendly sanitation helps to deliver a higher quality of life.
