Intended use Intended use
Intended use Intended use Intended use
For softening or partial softening of drinking water in multi-family houses,
housing areas, hospitals, and service water, process water, boiler
feed water, cooling water and air conditioning water (in accordance
with the relevant DIN 1988, Part 2 and 7) and for reducing malfunc-
tions and damage due to lime in water pipes and connected water-
carrying system components.
Function Function Function
Function Function
Rondomat Duo is a duplex softening unit which functions in accordance
with the ion exchange principle. The unit is run with columns continually
changed at short intervals. This method of operating ensures that soft-
ened water is even available during a regeneration procedure, while the
frequent column change minimises stagnation times. In terms of chemi-
cal and microbiological parameters, this leads to significantly better water
quality than with conventional alternating softening units.
Regeneration is triggered volumetrically (depends on the quantity of
water).
Very brief salt dilution times and short regeneration periods are achieved
as a result of a salt hopper for storing and dissolving salt and a new
quick-filling system for the brine container (patent pending).
The hardness of local untreated water is entered into the electronic
system when the unit is started. All other unit parameters are stored in
the electronic system. All unit data is preset and unit parameters can be
queried. The remaining capacity is displayed in liters or in bar-graph
form. The flow quantity is displayed in l/h during operation.

device that disinfects the ion exchanger during the regeneration process.
Spring-loaded non-return valves protect all connections on the upstream
side of the unit. This eliminates the need for a system or a pipe isolator.
