Wilo-RainSystem AF 150
Series description


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
Construction
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:

Description/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
