The VortSentry HS is a compact, durable stormwater treatment system utilizing helical flow technology to promote and enhance separation of floatables and other contaminants from stormwater flows. The VortSentry HS system is capable of achieving an 80% annual solids load reduction.

The VortSentry HS comes available in 3 configurations. An inline, a grate inlet configuration which can be designed for retrofit installations (if applicable) and combination of grate and pipe inlet. It is also available in 36 inch (900-mm) to 96 inch (2400-mm) diameter manholes.

In cases of flows exceeding the treatment capacity, the internal flow partition allows for excess flow to be diverted and exit the system without the need for external bypass structures.
