Wilo-RainSystem AF 150

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).

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

• 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

• Mains connection: 1~230 V (±10%), 50 Hz
• Max. negative suction head: 8 m
• Max. operating pressure: 8 bar
• Protection class: IP54
• Connections:
  • Discharge manifold R 1 ½
  • Inlets R 1 ¼, suction side inlets R 1 ¼
  • Overflow connection DN 100

• Pump housing: Stainless steel 1.4301
• Impeller: Noryl
• Shaft: Stainless steel 1.4031
• Mechanical seal: Ceramic/carbon
• Stage chambers: Noryl
• Diaphragm expansion tank: Steel, painted

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 1½ discharge manifold, including transmitter unit with diaphragm expansion tank (8 litres) following the volume flow principle and shut-off device with draining, manometer 0 to 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 fully electronic EC-Rain control device (Easy Control) via menu-driven rotary knob. Display of extensive messages. Available potential-free contacts for collective operation and collective fault signals.

• Factory-mounted rainwater utilisation system ready for connection
• Installation and operating instructions
• Level sensor (20 m cable, measuring range 0-5 m)

• Individual run/fault signals
