RainSystem AF 400
System
Make use of rainwater comfortably in large buildings.
- Compact, factory pre-assembled design enables easy installation
- Simple and intuitive operation via EC switchgear combined with Green Button Technology
- Automatic replenishment with drinking water permits reliable, continuous duty even in drought conditions
- Energy-saving operation by means of the flow-optimised design and the use of IE2/IE3 motors (Medana CH1-L) or IE5 motors (Medana CH3-LE, Helix2.0 VE)
- 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
- Maintenance notifications in the fault display via error codes
- 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

Design
Automatic rainwater utilisation system with hybrid replenishment reservoir with a volume of 400 litres and 2 non-self-priming, horizontal, multistage centrifugal pumps from the Medana CH1-L, Helix2.0 VE or Medana CH3-LE series. System installed on a vibration-insulated baseplate in a compact design including an 8-litre diaphragm expansion tank and fully electronic EC control unit (Easy Control) with control electronics and level control from up to two feeding pumps (ordered separately) (storage tank pump, 3~ 400 V).Application
Commercial and industrial rainwater utilisation for conserving drinking water as a hybrid system in conjunction with rainwater storage tanks or vesselsEquipment/function
- Module in compact design that is ready for connection, electronics and hydraulics already hooked up
- Vibration-insulated baseplate with height-adjustable pedestal, made up of:
- Two non-self-priming, corrosion-free, low-noise centrifugal pumps from the Medana CH1-L, Helix2.0 VE or Medana CH3-LE series
- Large-volume hybrid tank (400 litres) with integrated filling level sensor (cable length: 1.5 m, measurement range: 0 to 1 m), all connections, non-turbulent supply lines, overflow with siphon and connection options for extension module (ordered separately)
- Throughflow diaphragm expansion tank conforming to DIN 4807 for energy savings if there are very small leaks in the building
- Fully electronic EC-Rain switchgear (Easy Control) in a metallic housing, IP54 rating. With control electronics including solenoid valve, pressure transmitter 4–20 mA:
- Two separate LED displays (1 EC(e)-Booster printed circuit board to control up to two feeding pumps (storage tank pumps, 3~ 400V), 1 EC-Rain printed circuit board to control the high-pressure multistage centrifugal pump) show 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
- Dry-running and overflow meter
- Fault memory for the last 10 faults
- Level monitoring of the rainwater storage tank with overflow detection and metering
- Hybrid tank: High water alarm and overflow detection
- Over-/underpressure detection
- Dry-running protection of pump
- Automatic periodic water exchange in the hybrid tank (intervals selectable)
- Collective run and fault signals via potential-free contacts
- Optional inputs/outputs (see interfaces)
