Replenishing / system control

These represent the latest state of the art regarding rainwater harvesting. With the GRAF Aqua-Center -Silentio the system controls, the in-house replenishment tank and the pressure booster system are supplied pre-assembled as a complete replenishment module, so that the assembly time can be greatly shortened. Furthermore, all technical regulations are complied with. The Aqua Center-Silentio takes over the fully automatic control of the entire rainwater harvesting system. If dry, the control switches automatically to mains water mode. This mains water is transferred directly into the distribution network from the in-house replenishment tank via the pressure booster system. Even after a brief rain shower, the system switches back to rainwater operation, so that mains water consumption is limited to a minimum.
