D1’s cutting-edge M•Drive, available exclusively on the firm’s high-end Bay Collection® series since April 2006, is the highly intuitive, menu-driven spa controller, which provides effortless control over virtually every aspect of a spa’s operations and functions. D1 now offers this same technology as a new standard feature on hot tubs in the company’s Reflections® line! M•Drive features large buttons; a wide, brightly lit, screen; and an intuitive menu structure that makes the M•Drive the most ergonomically friendly spa controller in the world. 

The most sophisticated water management system that has ever been created maintains crystal-clear, sparkling water for you to enjoy, pure and simple.

• The world’s first UL-approved system that ozonates water while users occupy the spa
• 100% continuous filtration, processing over 10,000 gallons a day
• Minimizes chemical sanitizers (when Vision is used) 

Now, for the first time in the hot tub industry, there’s a water management system that integrates the benefits of ultraviolet germicidal light technology with the benefits of an ozone-based water sanitation system. D1’s new patent-pending UltraPure PLUS™ water management system is UltraPure, but now even better!

UltraPure PLUS offers a double-dose of microorganism destruction, once with ozone (a patented D1 process) and once with the new UV light germicidal, a more natural, non-chemical approach to disinfection. Minimize chemical use and cost. Limit the amount of time you spend on water maintenance. Get ultra clean, crystal-clear water and peace of mind. UltraPure PLUS is a new standard feature on hot tubs in the company’s Bay Collection line.
