14.1.2 Functional description–AquaA2

Brief description–AquaA2

Intended use–AquaA2
Field of application The AquaA2 option is an extension to the AquaA to obtain a two-stage
reverse osmosis system. The field of application of the AquaA remains
the same. The extension improves the quality of the product water.

Side effects–AquaA2
The improvement of quality involves a slightly reduced output compared
to that of a single-stage device. This does however not lead to a higher
water consumption as the concentrate of the second stage is returned
to the first stage.

Contraindications–AquaA2
– none

Restrictions–AquaA2
– none
The AquaA2 option is an extension for the
AquaA and is used to obtain a two-stage
dialysis water production and distribution
system. This option does not affect the
operating phases, but works synchronous to
the
AquaA .
ECO operation is supported by a reduction of
the output. This contributes to an energy-
efficient two-stage reverse osmosis
operation.
The AquaA2 is thus fully integrated into the
AquaA system as a module and represents
the expansion of the AquaA product line by
an additional efficient member for the
production of high-purity dialysis water.
The use of an AquaHT module ensures
automatic and stable sanitization.
