Danube W-Flow

Exceptional solutions, available with the semi cabinet design. We have now designed two sitting places. Immersive visuals: two sides illuminated fountain jets. A side-mounted filter housing is now placed at the end of the swimming area, so that the floating area is wider, more than 20 in. W-Flow: specific training solutions with customizable swim features.


Advantages of W-flow system:

  • It can deliver twice as much water against traditional types 47 550 Gallons per hour.
  • The width of the water flow is only 20-23 in.
  • 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 Danube swim spa is available with semi-cabinet – what makes it possible to sink the spa halfway only in the ground without any concrete preparation.

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: 2600 Gallons in 33 mins.
