The Rio Grande W-Flow Fitness Machine

Our pride and joy the Rio Grande W-Flow is the perfect combination of a well-equipped family hot tub and a swimming pool used as a “fitness machine” for a complete workout. The Rio Grande Swim Spa is really the best of both worlds. 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. It is a dual temperature swim spa, meaning the hot tub part is can be set warmer than the swimming area.

In the relaxation hot tub area each and every jet is illuminated, while the swimming section provides a greater than ever flow width. The massage experience is guaranteed by the hot tub’s 5 seats and 1 recliner. It is the perfect combination of a well-equipped spa and a swimming pool used as gym equipment suitable for a complete workout.

The new Rio Grande W-Flow swim spa is the result of a long development process. 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. The Rio Grande swim spa is equipped with brand new swim software. Combining this and the new W-flow system the new Rio Grande became a professional training appliance. 

The user can choose six-speed levels from the slowest, most comfortable „floating” to the hardest exercise. Similarly, to a modern treadmill, you can predefine the swimming speeds one after another, so you can insert slower stages between the swimming sprints. The flow rate can be adjusted 0.4-2.5 km / h.

Advantages of W-flow system:

  • it can deliver twice as much water against traditional types 180 m3/h

  • the width of the water flow is now 50-60 cm

  • the difference between water flow directions and the centre line of the spa is 0° therefore swimming is perfectly balanced

  • mechanical elements are separated from the hydro-space, so any mechanical repairs can be done without sluicing the water

  • the Rio Grande 2019 swim spa will be available with semi-cabinet - what makes possible to sink the spa halfway only in the ground without any concrete preparation

  • the heat pump connection in the swim spa is fix and equipped with In. Grid system - consequently, the heating cost can be reduced to one-third of the electrical heating

  • both the massage and the swim half can be separately controlled with the in.touch2 application

  • self-drain function - the swim half can be drained by the circulation pump: 10 m3 in 33 mins.

Thanks to the several training sessions it is suitable for professional swimmers and beginners too. You can experience the endless swimming with this new fitness machine. It’s like having your own coach to watch over you. The training session can be customized by setting flow intensities, durations and colour indicators. Before choosing a training drill, we recommend adjusting the parameters. Touch the settings icon on the right icon wheel. From there, you can access 6 different parameters.

Endurance A swimming workout executed at a constant intensity for the entire set duration.

Lap A swimming workout executed at high and low-intensity intervals of equal step time.

Transition A series of equal steps at random intensities.

Cardio A swimming workout executed at two successive steps at high intensity for one step at low intensity.

Power A pyramid program where the intensity will progressively increase until a maximum intensity level is reached. It will then decrease progressively to end at low intensity.
