Rio Grande

The Rio Grande W-Flow swim spa is the perfect combination of a well-equipped spa and a swimming pool used as gym equipment suitable for a complete workout. The inner width of the swim area is almost 2 meters, its length is 314 cm. In a traditional swim spa, the user has to switch on/off the pumps manually for finding the proper water flow which fits their fitness level. Wellis W-FLOW systems combine swim software to become a professional training appliance. The user can choose six-speed levels from the slowest, most comfortable to the hardest exercise-all without stopping to adjust speeds!…from a marathon swim to a sprint swim-you set your timings!

Due to the split layout of the Rio Grande, the water temperature, illumination and complete control of the swim area or the hot tub area can be regulated separately.

The Turbine – instead of the 3 hydromassage pumps- is capable to spin 50-160 m3 water per hour. In contrast to standard swim spa pumps it produces by 75% less power consumption while delivering twice the amount of water. In contrast to the Power model, the flow speed can be set to 6 different steps.
