AQA Perla is intended for the softening or partial
softening of drinking and non-drinking water for
domestic purposes (in keeping with the relevant
regulations – DIN 1988, Parts 2 and 7, and DVGW)
and for the protection of water pipes and the fittings
attached to them, equipment, boilers, etc. against
malfunctions and damage caused by calcification.
If AQA Perla is to be used for industrial purposes
expert advice must be sought.

Function

Function Function Function
AQA Perla is a duplex soft water unit based on the
ionic exchange principle. The unit is operated with
columns permanently alternating at short intervals.
This modus operandi ensures on the one hand that
soft water is also available during a regeneration
process, and that stagnation times are minimised by
the frequent column exchange on the other. This
leads to a significantly higher quality of water in
relation to chemical and microbiological parameters
than in the case of conventional shuttle soft water
units.
A regeneration is triggered volumetrically (dependent
on the water volume).
The unit is equipped with a device that disinfects
the exchanger resin during the regeneration.
Thanks to the special salt-dissolving storage tank
the shortest salt-dissolving times and hence
extremely short regeneration intervals are
achieved..
The microbiological quality of the softened water is
determined by the quality of the regenerative salt
used. We recommend that Sanisal/Sanitabs be
used exclusively.
During commissioning the local drinking water
hardness and the desired blended water hardness
are entered in the electronics. All other unit
parameters are stored. in the electronics. All unit
data are preset; unit parameters may be called up.
The residual capacity is displayed in litres and as a
bar chart. During operation the through-flow volume
is displayed in l/h.
Operation and display are done by means of a fully
graphic-capable TFT screen with integrated touch
panel. The combination of intelligent brine extraction
and a regeneration period adapted to the input
pressure ensures optimum use of resources.
A hygienic rinse after a longish down time is just as
programmable as a reminder to rinse the backwash
filter.
The AQUA-Watch function monitors the domestic
water supply for persistent minor (<60l/h)
percolations (persistent minor percolations are a
sign of a problem in the distribution network).
In the event of an error the control unit will issue a
warning. In the event of an error or power failure the
contact will be opened. (max. pin assignment 24
VDC; 0.5 A).
The connection of a mineral compound dosage
device and an error message system is possible
at any time.
The installer can leave his telephone number as
contact for the customer.
The unit stands out for its compliance with all
relevant national and international standards.

In the event of a power failure lasting more than 8
hours an automatic regeneration of both columns
will be triggered when power is resumed.
The programmed parameters have been safely
stored and are not affected by power failures.
