As a unique development, the filter compartment was placed at the end of the pool area, which increased the swimming area by more than 50 cm.

Technical Specification

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 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.

        • It can deliver twice as much water against traditional types of 180 m3/h.
        • The width of the water flow is only 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 heat pump connection in the swim spa is fixed 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.touch 2 application.
        • Self-drain function – the swim half can be drained by the circulation pump: 10 m3 in 33 mins.
