3.2.1 Functional description of the mounting rail
The mounting rail forms the interface between the water purification system, the
Conductivity Synthesizer, and the high-pressure pulsation system (HPS). A check
valve (1) prevents backflow of the conditioned water.
The synthesizer cartridge is connected to the mounting rail with quick couplings
(3). The shut-off valves (2) enable quick replacement of the cartridge or the filter
(e.g. during maintenance activities). From the support console, the circulation of
the Conductivity Synthesizer is connected from above (7).
A filter (4) protects the downstream Conductivity Synthesizer from possible
impurities in the water. After the filtration the DI water is connected to the
Conductivity Synthesizer (9) and the product is returned to the mounting rail (10).
The DI water (5) and the product (6) can be sampled at any time over the sampling
taps (5/6).

3.2.2 Functional description of the SynPur
In certain environments (e.g. „clean rooms“, ESD-protected areas, etc.), the water
to be atomized must be free of minerals (DI water = fully demineralized water). The
SynPur has the task of removing all of the minerals from the already purified water
in order to introduce minimum quantities of CO2. The product is a specially treated
(conditioned) water that is fed to the HPS to be atomized.
All internal processes of the SynPur are managed by a programmable logic
controller (PLC).
The function of the SynPur is explained below. The display shows the functional
status based on a stylized flow diagram and LED’s. A detailed description of the
display is found in Section 4.3.3.
