  • BluFusion™ represents a refined approach to spa water care—designed for owners who value comfort, consistency, and ease of ownership. Powered by BluFusion™ technology, the system automatically generates bromine sanitizer directly from salt in the water, eliminating the need for traditional tablet feeders and complex setup procedures. Unlike many salt systems that require extended startup periods and multiple adjustment cycles, it is designed for a straightforward, efficient setup process, allowing owners to enjoy their spa sooner with fewer steps and less waiting. Sanitizer production begins automatically during normal spa operation, helping establish usable water conditions with out prolonged downtime. Once operating, it continuously produces bromine as needed, supporting more stable water conditions over time. The result is clean, clear water with a noticeably softer feel and reduced chemical odors.

    • STREAMLINED STARTUP DESIGNED TO REDUCE SETUP TIME AND COMPLEXITY

    • MORE CONSISTENT SANITIZER PRODUCTION DURING NORMAL USE • INTEGRATED SACRIFICIAL ANODE TO HELP MANAGE METALS AND PROTECT COMPONENTS

    • REDUCED RELIANCE ON TRADITIONAL CHEMICAL HANDLING
