DEL has been the leader in environmentally-sound ozone systems since 1980. Ozone systems sanitize and clarify swimming pools and spas naturally while removing environmental by-products. Sanitation is achieved by passing air through a high voltage electrical discharge, or corona. DEL has expertise in ozone applications in a wide variety of markets. DEL ozone systems deliver consistent doses of oxygen reliably and efficiently and offer on-site expert consultation and support. The EPA, FDA and USDA have all approved the DEL ozone as an antimicrobial substance for water purification and surface sanitation. With more than 30 years experience in ozone engineering and application knowledge, DEL’s residential ozone generators significantly reduce overall chemical use, clarify water, improve filtration, and leave no toxic by-products.
