Product Overview & Area of Application
The Aqmos water softener system R2D2-32 Black Edition is a compact softening system in a cabinet-style housing designed to reduce water hardness in the drinking water sector. It is designed for smaller households with 1 to 4 people and is particularly suitable for single-family homes, apartments, or smaller properties with limited space in the technical area.
The variant with connection set and mounting block is prepared for orderly integration into the house water installation. The goal is to reduce limescale deposits on fittings, pipes, water heaters, and water-bearing household appliances.
Technology & Equipment
The R2D2-32 Black Edition operates with a volume-controlled BNT 1650 control valve. The control valve records water consumption and controls regeneration based on demand, so that salt and water are used not purely time-dependent but according to usage.
Softening is carried out according to the ion exchange principle. In this process, calcium and magnesium ions, which are responsible for water hardness and limescale formation, are exchanged for sodium ions in the softening resin. The compact cabinet-style housing combines the softening unit and salt tank in a space-saving design.
Everyday Benefits
Softer water can reduce limescale residues on fittings, shower surfaces, and household appliances, thereby reducing daily maintenance effort. After professional setup, the automatic, volume-controlled regeneration works in the background and supports consistent operation of the system.
The integrated salt tank holds up to 25 kg of regeneration salt. This keeps the system clear in operation, and the salt supply can be checked directly in the housing and refilled as needed.
System Integration & Compatibility
The water softening system is integrated into the building's cold water line. Installation typically takes place after the water meter, water filter, and, if applicable, pressure reducer. Operation requires a frost-free and dry installation location, a power connection in the immediate vicinity, and a drain connection for regeneration water.
The mounting block supports bypass function, isolation of the system from the house water network, sampling, and adjustment of residual water hardness. The residual hardness should be checked after commissioning and adjusted to suit the installation.

Assembly
Assembly takes place in the household water line after the water meter, water filter and, if applicable, pressure reducer. A protective filter should be installed upstream of the system to reduce contamination and sludge buildup in the softening system. The mounting block must be installed according to the direction of flow.
For installation, a suitable drain connection for regeneration water, a power connection in the immediate vicinity and a frost-free, dry installation location are required. Work on the drinking water installation should be carried out by qualified installation personnel.
Notes
The system is intended for the drinking water sector to reduce water hardness. The local raw water hardness must be taken into account during commissioning and set accordingly on the control valve. Regeneration salt tablets according to DIN 19604 or DIN EN 973 Type A must be used for operation.
The residual water hardness should be checked after commissioning and adjusted via the blending. A blend of 6 to 8 °dH is recommended in the manufacturer's documents to avoid fully softened water in the household network.
