QuadroLimit

Description

QuadroLimit combines the benefits of the QuadroControl system shaft with the advantages of proven stainless steel vortex valves (manufacturer: UFT Umwelt- und Fluid-Technik Dr. H. Brombach GmbH). QuadroLimit is dimensioned and manufactured to the specific project needs. The shaft, which is ready to be installed, can be easily incorporated anywhere in the system along the side of the detention/infiltration system. No separate construction is required downstream of the detention/infiltration system. If necessary, an integrated emergency overflow may be installed to limit the maximum water head (Quadro-overflow).

Vortex shaft for Rigofill-type stormwater detention systems:
Plastic shaft, block-shaped, consisting of one or several shaft bodies plus cone, material: polyethylene (PE), colour: black, dimensions: 80 x 80 cm, height depends on the number of layers of the connected detention/infiltration unit (DIU), dimension compatible to Rigofill inspect, with DO 600 extension pipe, clear access diameter: 500 mm. With integrated stainless steel vortex valve, manufacturer: UFT Umwelt- und Fluid-Technik Dr. H. Brombach GmbH, outlet diameter between DN/OD 250 KG and DN/OD 400 KG (depending on drainage efficiency and head), vortex outlet range between 4 and 80 l/s (other values available upon request).
