Descriptive

• Regulation tanks made of 100% recyclable polyethylene, reinforced, with anchoring and lifting rings equipped with a Vortex regulator
• Rainwater storage capacities ranging from 2000 to 10,000L
• Anti-slip cover passage diameter 676 mm, closure by 1/4 turn and safety screws
• Vortex mounted on PVC elbow in low output Dn110.
• Note: the overflow rating is reserved for tanks with Vortex effect, ref. ET-----RX

Control device

• Hydrovortex, made of stainless steel 304
• The Vortex device makes it possible to maintain a relatively large passage section for very low flow rates (e.g. 40 mm per 1 l/s) whereas to guarantee a flow rate of 1 l/s with a simple nod, a 20 mm orifice would be required.

The principle of low regulation

• The control tank makes it possible to limit the flow in the event of a storm
• In the case of heavy rain, the water enters the tank with maximum flow and comes out of the tank in the lower part with a controlled flow rate
• If the volume of the tank is not sufficient, the flow is then evacuated by the overflow of emergency to avoid flooding upstream.
