3.1
Variants of the Pure Water System
The system is very flexible. Customer specific systems are oriented to the amount of pure
water needed. All systems have a water softener and a pure water system. This two stage
water treatment yields very soft water (0-1°dH, 17 ppm) which is also demineralised (95-
99%).
The system variants described below just illustrate the most frequent applications. It goes
without saying that each system can adapt to customer needs. Each customer receives a
diagram which is only applicable to the given customer system. The customer specific con-
figuration is shown in the diagram.
3.1.1
Water Softener and Clear Water System
The minimum configuration (see p. 8, view of basic system) consists of a water softener, an
installation rail, a pure water system and a storage tank. These system parts form the basis
of all system variants. Water circulation is completely closed; this is of great importance
from the point of view of hygiene. The water produced by this basic system is primarily
used for DRAABE Air Humidification or as process water for printing presses.
The water fed into the system (drinking water) is softened by the water softener (0-1°dH, 17
ppm), filtered through the two stage filter combination and, in the last treatment stage, de-
mineralised by the pure water system. The pure water system also retains organic sub-
stances.
The pure water system provides a remote fault indicator. The closer, in its closed state, sig-
nals that there is a fault. This contact can turn an optical or acoustic transmitter on or off or
can be used by the building services management system (BMS). The pure water system
also organises the optimum regeneration point of the water softener.
The pure water produced by the system is stored in the storage tank (mounted on wall or
standing).
