Wilo-RainSystem AF 150

Convenient rainwater utilisation in multi-residential buildings and small commercial businesses.

Your advantages
NEW

Convenient rainwater utilisation in multi-residential buildings and small commercial businesses.

Through the targeted use of rainwater, the Wilo-RainSystem AF 150 is a particularly sustainable system for saving drinking water. The factory pre-assembled system can be installed quickly and put into operation swiftly using the RainControl Professional switchgear. 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 IE3 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.


Your advantages

  • Compact, factory pre-assembled design enables easy installation
  • Simple and intuitive operation via the RainControl Professional switchgear
  • Automatic replenishment with drinking water permits reliable, continuous operation even in drought conditions
  • Flow-optimised design and deployment of IE3 motors enable energy-saving operation
  • Self-protection routines, control in the low voltage range and the use of corrosion-resistant components facilitate high operational reliability
  • Maintenance notifications in the fault display via LCD messages
  • Quiet operation for high level of user comfort

Construction

Ready for connection rainwater utilisation system in compact construction, with full electric and hydraulic connections already in place and installed on vibration-insulated painted tubular steel frame.

Pipework: R 1 1/2 discharge manifold, including transmitter unit with 8 l diaphragm expansion tank following the volume-flow principle and shut-off device with draining, manometer 0 – 10 bar, and ball valve on the suction and discharge side. High operational reliability due to two separate suction lines (to be created on-site).

High-volume replenishment reservoir for needs-based replenishment with drinking water in the consumer network when rainwater storage tanks are not full.

Connection for backflow warning is available as standard.

Pumps: 2 self-priming, corrosion-free, low-noise centrifugal pumps from the Medana CH1-LSP series.

Operation and parameterisation of the all-electric controller RainControl Professional is done using menu-operated function keys. Display of extensive messages. Available potential-free contacts for collective operation and collective fault signals.
