A very basic lesson we learned as students in geometry class is that the shortest distance between two points is a straight line. This principle has been put to work for the first time ever in a spa with Artesian’s DirectFlow water management system. DirectFlow gives spa users total control of their water massage, or hydrotherapy, without sending the water on a roundabout route through diverter valves that cause loss of water pressure and diminished massage. While the implications of this technology are immense, the lesson is this: Your spa seat and your jets are controlled by you with your own personal topside control, and your massage is delivered straight to you without diversion – or distraction from noisy diverter valves!
