A professional counter-current swimming machine from EVA Optic (EVAstream range) — the quietest counter-current system on the market, built around patented turbine technology.
Twin turbine. Adjustable flow from around 110 up to 550 m³/h, driven by two turbines for the widest, most powerful current — built for larger private pools, hotels, spas and training use where a serious endless-swimming or resistance current is wanted.
The unit is recessed into the pool wall in an EVAstream niche (concrete or liner) and finished with a stainless steel face plate, for a clean, flush fitting rather than a bulky bolt-on unit. Flow speed is set through the ECA control unit.
Sold as a system: this listing is the twin-turbine 550 unit. Add the matching niche (concrete or liner) and the stainless steel face plate; the control unit and jet configuration are specified to suit your pool.
Every counter-current install is different — tell us your pool size and how you like to swim, and we will size and specify the right EVAstream setup for you, free of charge.
