Applications

Hybrid system for commercial and industrial rainwater utilisation for reducing potable water consumption in connection with cisterns or tanks.

Toilet flushing

Sprinkling/irrigation

Supplying machinery

Secondary cleaning purposes and other applications in the non-potable water sector

Function/construction

Connection-ready water supply system with 2 to 4 water supply pumps as compact module for commercial and industrial rainwater utilisation. For fully automatic rainwater supply from an underground tank or a cistern by means of submersible pumps as feeding pumps. Depending on the pump design, greater distances between the system and the cistern can also be bridged with this hybrid system (see in this connection Wilo-Submersible pumps in the Wilo-Drain TS series). The large-volume hybrid vessel with all of its integrated functions offers requirements-oriented replenishment of potable water into the consumer network when cisterns are not full. The completely electronic regulatory unit for controlling the water supply pumps and cistern pumps is equipped with a main switch, control switches for each pump with Manual-0-Automatic function, and a display of the operation/malfunction operating states for each pump as well as low water levels. Depending on pressure, the pumps are switched on and off in cascading fashion in accordance with water requirements. A cross-flow diaphragm pressure vessel in accordance with DIN 4807 provides energy savings when there is minor leakage at the building site.
