Make use of rainwater comfortably in large buildings.
Recommended services
Your advantages
- Low-noise due to optimised overall flow and noise concept (multistage centrifugal pumps)
- Maximum operating reliability through the use of fully electronic RainControl Hybrid controller
- High economic efficiency due to needs-based fresh water replenishment
- Automatic control of the feeding pump
- System/level control in low-voltage range
Design
Automatic rainwater utilisation system with hybrid tank (400 litres) and two non-self-priming pumps from the Medana CH1-L series
Application
- Rainwater utilisation or fresh water replenishment in case of drought in large commercial or industrial buildings
Equipment/function
- Module in compact construction 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 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, protection class IP54. With control unit electronics including solenoid valve, pressure transmitter 4–20 mA:
- o Two separate LED displays (1 EC(e) booster circuit board to control the feeding pump, 1 EC-Rain circuit board to control the high-pressure multistage centrifugal pumps of the Wilo-Medana CH1-L series) 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
- Calcination protection of the two-way valves
- Automatic periodic water exchange in the hybrid tank (intervals selectable)
- Collective run and fault signals via potential-free contacts
- Optional inputs/outputs (see interfaces)

Construction
Rainwater utilisation system ready for connection in compact construction, with all electronics and hydraulics already hooked up and installed on vibration-insulated baseplate with height-adjustable pedestal.
Pipework: R 1 1/2 discharge manifold, including transmitter unit with 8 l diaphragm expansion tank 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-volume replenishment reservoir in a hybrid design (holds both drinking water and rainwater) 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: Two non-self-priming, corrosion-free, low-noise centrifugal pumps from the Medana CH1-L series.
Operation and parameterisation of the fully electronic EC-Rain switchgear (Easy Control) via menu-driven rotary knob. Display of extensive messages. Available potential-free contacts for collective operation and collective fault signals.
