Wilo-RainSystem AF 150

Your advantages

  • Low-noise due to multistage centrifugal pumps
  • All parts in contact with the fluid are corrosion-free
  • Maximum operational reliability due to fully electronic RainControl Professional controller
  • High economic efficiency due to needs-based fresh water replenishment
  • High reliability, due to flow- and noise-optimised replenishment reservoir
Series description

Design

Automatic rainwater utilisation system with run-down tank and 2 self-priming pumps

Application

Rainwater utilisation in multi-family houses and small trade businesses for saving drinking water in conjunction with cisterns or tanks

Equipment/function

Connection-ready module with compact construction, electrical and hydraulic connections already in place, mounted on vibration-insulated painted steel pipe frame, comprising:

  • 2 self-priming, corrosion-free, low-noise MultiCargo MC series centrifugal pumps
  • Pressure-side R 1 1/2 joint tubing including transmitter unit with 8 l diaphragm pressure vessel with flow-through design and shut-off device with drain
  • Pressure gauge 0-10 bar
  • Ball valve on suction and pressure side
  • Large-volume fresh water replenishment reservoir (150 litre) with mechanical float valve
  • RainControl Professional central switchgear with control electronics including solenoid valves, pressure transmitter 4–20 mA and level sensor with 20 m cable for monitoring levels
    • Menu-prompted operation and LCD display of run/fault signals
    • Steady system control by means of cyclical pump cycling and integrated test run on idle pumps
    • Automatic fault-actuated switchover and peak-load operation
    • Automatic water exchange in the replenishment reservoir
    • Automatic prevention of lime deposits on the solenoid valve
    • Permanent display of rainwater storage tank level, system pressure and operating status via LCD

Construction

  • Connection-ready double pump water-supply unit as compact module for multi-family houses and public buildings
  • For fully automatic supply of rainwater from an underground tank or rainwater storage tank.
  • High operational reliability through the use of two separately guided suction lines (to be provided on-site).
  • Large-volume replenishment reservoir for needs-based replenishment of drinking water into the consumer network when rainwater storage tank is not full
  • Standard-equipped with connection for back-up warning
  • Flow-through diaphragm pressure vessel in acc. with DIN 4807 for energy-saving with very small building leaks.
  • Consistent system control is achieved through cyclical pump cycling and an integrated test run when the pumps are at rest
  • Automatic fault-actuated switchover and peak-load cut-in guarantee maximum system availability.
  • Drinking water replenishment is fully automatic and demand-optimised
  • Pump-operation-dependent water replacement in the replenishment reservoir is also performed automatically.
  • With integrated electronic motor protection, integrated dry-running protection system for pump unit as well as automatic protection of the solenoid valve against lime deposits
  • Control device displays extensive signals; it is also equipped with potential-free contacts for collective run signals and collective fault signals
  • Operation and parameterisation of the fully electronic RainControl Professional controller is performed by means of menu-driven function keys
  • Permanent display of rainwater storage level, system pressure and operating status via LCD
  • System is ideal for connection to building automation system

Delivery state

  • Two self-priming, MC multistage centrifugal pumps
  • 150 l fresh water replenishment reservoir, transmitter unit with 8 l diaphragm pressure vessel,
  • RainControl Professional central switchgear with control electronics, level sensor
  • With 20 m cable, measurement range 0-5 m.
