The HydroStyx® Discharge Brake is a vortex-based energy dissipation system designed to reduce high discharge velocities in stormwater and wastewater networks. Its unique geometry ensures turbulence control and gentle outflow into natural water bodies or downstream infrastructure, preventing erosion and structural damage.

Vortex-induced flow braking
Low-maintenance, passive design
Ideal for steep gradients & high velocity
Up to 600 l/s
Stainless steel construction
Inline or end-of-pipe
DN 100–DN 600
Vortex flow dissipation
Stormwater outfall protection
Energy dissipation at pipe exits
Erosion control in steep drainage systems
Overflow calming in detention systems
Suitable for stormwater, rainwater runoff, and combined wastewater discharges.
Reduces exit velocity by up to 90%
Eliminates need for concrete stilling basins
Prevents scouring of natural surfaces and banks
Integrated flow measurement
Tailor-made outlet transitions
Anti-vortex plate for ultra-sensitive zones
From forging and casting to machining, assembly, and testing — every step is managed under one roof to ensure consistent quality, faster lead times, and zero compromise.
