RioGrande W-Flow

The new Rio Grande W-Flow swim spa is the result of a long development process. It 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.

NEW W-Flow System

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 2019 swim spa is equipped with brand new swim software. Combining this and the new W-flow system the new Rio Grande 2019 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 centerline 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 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.
