Description

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.
Advantages
- Compact, factory pre-assembled design enables easy installation
- Simple and intuitive operation via EC switchgear combined with Green Button Technology
- Reliable, continuous operation by means of automatic replenishment even in drought conditions by switching over to drinking water via two three-way valves
- Flow-optimised design and use of IE2 motors enable energy-saving operation
- Self-protection routines, control in the low voltage range, the use of corrosion-resistant components and the optional integration into a building management system facilitate high operational reliability
- Possibility of connecting a feeding pump in the rainwater storage tank via AUX contact (additional switchgear required)
- Remote monitoring possible through the integration into building automation via standard Modbus and optional extended communication via a gateway
- Quiet operation for high level of user comfort

Technical Features

Design

Automatic rainwater utilisation system with replenishment reservoir with 150-litre volume and 2 Medana CH1-LSP self-priming, horizontal, multistage centrifugal pumps. System installed on a vibration-insulated tubular steel frame in a compact design including an 8-litre diaphragm expansion tank and fully electronic EC control unit (Easy Control) with control electronics and level sensor (including 20 m cable, measurement range 0 – 5 m).

Application

Rainwater utilisation in multi-residential buildings and small commercial enterprises for conserving drinking water in conjunction with storage tanks or tanks

Equipment/function

Module in compact construction that is ready for connection, electronics and hydraulics already hooked up
Vibration-insulated tubular steel frame with height-adjustable pedestal and baseplate for attaching pumps, made up of:
Two self-priming, corrosion-free, low-noise centrifugal pumps from the Medana CH1-LSP series
Fresh water replenishment reservoir (150 litres) with mechanical float valve
Throughflow diaphragm expansion tank conforming to DIN 4807 for energy savings if there are very small leaks in the building
Fully electronic EC Rain control device (Easy Control) in metal housing, protection class IP54. With control unit electronics including two three-way valves, pressure transmitter 4–20 mA and filling level sensor with 20 m cable for fill level monitoring:
- LED display to output operating data, controller parameters, operating statuses of the pumps, error messages and history memory
- Menu navigation with seven-segment display and visualisation
- Factory-preset parameters for easy commissioning/start
- Setting of operating parameters and acknowledgement of fault messages using rotary knob
- Lockable main switch
- Elapsed time indicator for each pump and for the entire system
- System/level control in low-voltage range (24VDC)
- Level monitoring of the rainwater storage tank with overflow detection and metering
- Optional overflow detection for replenishment reservoir
- Over/underpressure detection
- Dry-running protection of pump
- Self-priming support
- Calcination protection of the three-way valve
- Fault memory for the last 10 faults
