Wilo-RainSystem AF 150
Convenient rainwater utilisation in multi-residential buildings and small commercial businesses.
Convenient rainwater utilisation in multi-residential buildings and small commercial businesses.
Through the targeted use of rainwater, the Wilo-RainSystem AF150 is a particularly sustainable system for saving drinking water.
The factory pre-assembled system can be installed quickly. The EC switchgear and Green Button Technology allow it to be put into operation swiftly. The system is equipped with a replenishment reservoir with a volume of 150 litres for continuous operation. It switches automatically to drinking water replenishment if the rainwater level is low in the rainwater storage tank.
Low energy consumption is ensured by the Wilo-Medana CH1-LSP integrated, self-priming centrifugal pump with IE2 motor technology in combination with the flow-optimised design of the replenishment reservoir. The power supply in the low-voltage range, self-protection routines (such as dry-running protection) and corrosion-resistant components provide for a high degree of operational reliability and durability. The quiet operation allows applications directly in the living area.
The system can be integrated in an existing building management system via a Modbus RTU interface. Extended communication via a gateway is optionally available.
